With the rapid development of modern computer science and the application and promotion of information and communication technology, the teaching management models of various schools are undergoing tremendous changes. The education and practice of informatization and digitalization of school teaching management work are also receiving more and more attention. Students' course selection work is closely related to students' academic studies and teachers' teaching work, and is also an important part of information management in colleges and universities. The purpose of school-wide elective courses is to expand students' knowledge, strengthen students' quality education, and cultivate compound senior talents, which is of irreplaceable importance.
Today's society has increasingly higher requirements for education level and teaching management software and hardware, which puts forward more requirements for a school to have a complete set of teaching management software. To realize this function, school administrators are required to be equipped with an efficient education management network system so that they can implement a good set of complete management within the school and respond to the needs of teachers and students as quickly as possible, providing them with timely services. Provide services and provide them with an efficient and convenient environment. The performance analysis system under the online and offline teaching mode is an important application system in the campus network. It has greatly improved the basic environment of school teaching, scientific research and management, and reflects the modernization level of school management to a certain extent.
In our country, the performance analysis system under the online and offline teaching models of various schools is not a new topic, but there are still many places that do not have advanced equipment to develop such systems. For example, in poor mountainous areas, their current education model still remains In this state of manual work, if we want to develop the education industry to be more precise, better, and prioritized, we must use advanced technology to reduce costs. Therefore, it is inevitable for machines to replace humans. Only by scientifically using modern technology, corresponding artificial and The cost will be reduced. While these foreign technologies are already quite mature, our country's network technology has just begun, which makes our country's technology lag behind. Now more and more people are beginning to develop some systems to enable our country's technology to make breakthroughs. Therefore, it can be seen that with the rapid development of education in our country, the application of information technology will become more extensive and in-depth. However, compared with developed countries, the application level of information technology in my country's education industry is still very low. It is only in big cities. Computers are used for large-scale operations only in colleges and universities that developed earlier and are larger in scale.
Based on the information data obtained from market research, combined with domestic and foreign cutting-edge research, and using relevant system development and design methods, we finally designed a performance analysis system under the online and offline teaching mode.
This article has seven chapters in total, as shown below.
The first chapter outlines the research purpose and significance of the performance analysis system under online and offline teaching modes; it concisely summarizes the research status and future research trends in the field of warehousing at home and abroad, and finally gives the structure of the paper.
Chapter 2 provides a brief overview of the development techniques and tools used in this article.
Chapter 3 briefly conducts demand analysis and feasibility analysis on each business process of the system.

Chapter 6 uses test cases to test some main functional modules of the performance analysis system under online and offline teaching modes, and finally obtains the test results.
Chapter 7 summarizes the full text and makes an outlook for future research.
The front-end part of this system is developed based on the MVVM model, using the B/S mode, and the back-end part is developed based on the Java springboot framework.
Front-end part: The front-end framework uses the popular progressive JavaScript framework Vue.js. Use Vue-Router and Vuex to realize dynamic routing and global state management, Ajax to realize front-end and back-end communication, Element UI component library to quickly prototype the page, and the project front-end to achieve responsiveness through grid layout, which can be adapted to PC, tablet, mobile phone, etc. Perfect layout display for different screen sizes.
Back-end part: Use springboot as the development framework, and integrate MyBatis, Redis and other related technologies.
Now the Mysql database can support many users on the network, and can also adapt to the deployment or configuration of customer servers and servers. Our servers and clients here are actually a software concept, and the computer hardware we use is also There is no one-to-one correspondence with them.
Mysql is a very popular relational database management system. It has always been the leader. It is not only very powerful, but also very convenient to use. Mysql's cross-platform capabilities are also very good. Software developers like it very much. of these powerful advantages. Different from other relational databases, it has its own set of solutions for database management. Database management is achieved by setting corresponding permissions and roles for users. It can be seen that Mysql is a database management software suitable for high throughput, high reliability and high efficiency.
Advantage 1: Mysql sets different permissions for users with different identities to complete different business logic, which makes Mysql far beyond other relational databases in terms of security and integrity.
Advantage 2: Mysql can also support data types such as animations, graphics and sounds, which shows that Mysql can also support multiple data types.
Advantage three: Mysql can also be developed on multiple platforms, and multiple programming languages for software development can operate the Mysql database.
Tomcat is a free server. The usage scenario is more suitable when the number of visits is relatively small. This means that when Tomcat is installed on the computer, the access request of the front-end HTML page can be parsed through it. In fact, Tomcat is an extension of Apache, but it operates relatively independently from Apache. Therefore, it can be regarded as running as a relatively independent process from Apache.
Tomcat was originally developed and applied by Davidson of Sun Company. Through his efforts, it has been continuously turned into an open source server. It was also handed over to the Apache Software Foundation by Sun. The ever-evolving tomcat server has undergone a lot of reconstruction and combing in the latest version, making it more convenient to use. The Tomcat load balancing algorithm is an open source software implementation. There is no need to add additional hardware investment, and it is very convenient to implement. It is especially suitable for the expansion of general small business website servers now and in the future. Judging from current practice, it can be used as a reference for similar applications.

- Java description
Java is a platform computer language technology, which mainly includes two parts: JAVA Virtual Machine (Java Virtual Machine, JVM) and JAVA API (Application Program Interface, application interface programming).
I personally have a deep understanding of the two languages: C language is more of a creation tool, while Java is more of a usage tool. We know that many of the underlying implementations of Java are actually implemented in C language, so we can see this even more. In the process of using Java, we need to be able to use API documentation, which can be regarded as Java usage instructions. The object-oriented characteristics of Java allow it to have many encapsulated objects. When using it, we only need to know the behavior of the object (which is also the method of object encapsulation). Here we must pay attention to whether the method is a static method or a regular method, because when calling, there is a gap Very big. In the future, there will definitely be a programming language that is more user-friendly and easier to develop than Java, but it will definitely not be completely different from the Java language. As the saying goes, "You can use a stone from another mountain to attack a jade." Learning Java well can also make it easier for us to learn better. other languages.
System feasibility analysis is essential in the process of software development. Feasibility research is to evaluate whether the problem can be solved and to solve it in the least time and at the least cost. In order to achieve the above goals, it is also necessary to consider the advantages and disadvantages of the methods to solve these problems, and also consider the economic benefits brought by the development of these system scales. Here we can conduct feasibility studies on our system based on technical feasibility, operational feasibility, and economic feasibility. The feasibility analysis of the performance analysis system under the online and offline teaching mode is as follows:
The performance analysis system under the online and offline teaching mode uses the Java programming language combined with Java and SERVLET. The database part uses the currently popular Mysql database. All data resources in the performance analysis system under the online and offline teaching mode are stored In the Mysql database, this system uses AJAX asynchronous operations in many places. AJAX technology can partially refresh the data specified by the user, which not only reduces the server's parsing of the page but also greatly increases the user experience. The environment configuration of this system is also relatively simple, because the Myeclipse editor is used, and Myeclipse has its own Tomcat server and JDK environment, so we do not need to reconfigure it.
This system uses Java and Mysql to support transaction and data logic and uses H5 to display the front-end page.
Different components in HTML web pages are identified in the form of tags. The following is the basic composition layout of HTML:
Figure 3-1 Basic structure diagram of HTML
The performance analysis system under the online and offline teaching mode runs in the environment of Java and Mysql, and the cost of the system is mainly distributed in the development and maintenance of the software. But if the system is put online and put into use, it will not only facilitate people, but also save users' time and energy. It will also greatly facilitate operators and reduce their work intensity. The performance analysis system under the online and offline teaching mode is actually not too complicated. The economic expenditure during development is not large, and the time used in developing the system is not much. The advantages in terms of time and economic benefits far exceed The cost of maintenance and management makes it feasible and appropriate to develop this system.
This system is a performance analysis system in online and offline teaching modes based on browsers and servers. After the system is developed, users only need to enter the correct URL address in the browser to access it. The front page of this system is simple and clear, and can be operated without operating guidance. Whether it is the system administrator or the school user, all operations on the page are completed in the browser, so as long as the computer is connected to the Internet In this case, it can be operated by opening the browser. Moreover, there is no need to perform relevant environment configuration before use, so the system is convenient, simple, and easy to use, so the system is easy and operable.
According to the user's needs for the system, the system is required to be simple to operate and able to manage information accurately and completely. After analyzing the needs of the performance analysis system under the online and offline teaching mode, the entire system is mainly divided into two parts: administrators and users, and teachers. The branch functions under each module are different. The function is explained as follows:
Administrator module: Home page, personnel management (administrators, student users, teacher users) module management (course information, daily grades, final grades, comprehensive grades, class grades, grade analysis).
Student user module: Home page, module management (course information, usual grades, final grades, comprehensive grades, grade analysis).
Teacher module: Home page, personnel management (student users) module management (course information, daily grades, final grades, comprehensive grades, class grades, grade analysis).

The business process of the performance analysis system under the online and offline teaching mode is shown in the figure below.
Figure 3-3 System business flow chart
The administrator has the highest authority. After adding, deleting, and modifying various information, the content of the backend database will be updated. Users can log in to carry out homepage, personnel management (administrators, student users, teacher users) module management (course information, daily Instruction actions such as grades, final grades, comprehensive grades, class grades, grade analysis) will also update background data.
Different from the program flow chart that emphasizes control logic, it is more concerned with the specific flow of data in the entire system and the entire objective process of data processing, and is a description of data specifications. Because of this, system data flow diagram is very popular as an extremely important description tool in system structured analysis methods.
The top-level data flow of the performance analysis system in online and offline teaching modes is shown in the figure below.
Figure 3-4 System top-level data flow diagram
The top-level data flow of the system: the external entity is the user, the first process is login verification, the user information table returns the password verification, whether it is correct, if it is correct, log in to the system, if it is wrong, feedback information will be given. After logging in to the system, according to the function selection of different users, Read and write the database.
The underlying data flow of the system is shown in the figure below.
Figure 3-5 System underlying data flow diagram
The underlying data flow of the system: external entities are administrators, student users , and teacher users . Data flows from administrators, student users , and teacher users respectively flow to the system data process. Data tables provide data support to complete logical operations.
Since this system operates the database frequently in terms of logical transaction processing, the system does not use native JDBC when connecting to the database at the bottom layer. Instead, it encapsulates JDBC. After encapsulation, it is equivalent to a tool DBUTIL for connecting to the database. When used like this It will be more convenient and encapsulation in this way can also reduce the redundancy of code in the system. When we need to connect and use the database, we only need to call a method in this tool. Moreover, through encapsulation, the operations on the database can be made independent. When different types of databases need to be connected, only modifications are needed to achieve the purpose.
The DAO layer does not originally have this class. It is just a model concept in the MVC structure in Java, mainly some methods in it, and these methods are used to access the database. When we develop software in the DAO layer, we usually put the interface and the implementation class of the interface. We call it an interface to standardize the implementation class. The implementation class is mainly used to manipulate the database.
MVC is a key model for system development. M is the Model model. It is the core of the operation of key programs within the system and mainly performs various operations on the database. View View is V, also called a view. Its main function is to display some data. Controller Controller is a C implementation that reads data from the view layer of the View and then controls the user's input.
The system architecture is shown in the figure below.

- 数据库连接设计
-
该系统的数据库连接方法采用的是C3P0数据连接池的方法，C3P0是开源的JDBC连接池，jdbcURL是所创建的数据库，driverClass连接数据库驱动，user为用户名，password为用户密码，acquireIncrement当连接池中的连接耗尽的时候C3P0一次同时获取的连接数，initialPoolSize初始化连接池中的连接数，minPoolSize和maxPoolSize分别是连接池中保留的最小和最大的连接数。C3P0的特点在于有自动回收空闲连接的功能。
数据库连接池配置代码如下所示。

- 系统实现
- 登录模块的实现
该登录模块利用js进行设计，JavaScript函数CheckSubmit()对输入框是否为空进行验证，使用js的技术结合Mysql 2012数据库的查询语句进行登录信息的验证。首先从文本框中分别获得账号user_name和密码user_pw，使用Sql语句“select * from t_user where user_name=‘”+user_name+“’ and user_pw=‘”+user_pw+“’”将查询结果赋给rs结果集，若rs.next()返回值为空，表示数据库找不到该用户数据，若rs.next()返回值不为空，则显示登录成功，进入主界面。
用户登录流程图如下所示。
图5-1用户登录流程
用户登录流程：用户只有输入正确的用户名和密码才会成功进入系统，用户输入用户名密码后点击登录按钮，系统会进行校验该用户名是否存在，如果用户名与密码不匹配或者用户名不存在，则返回主界面。
系统登录界面如下图所示。
图5-2系统登录界面
登录功能的逻辑代码如下所示。
* 登录
* @param data
* @param httpServletRequest
* @return
*/
@PostMapping("login")
public Map<String, Object> login(@RequestBody Map<String, String> data, HttpServletRequest httpServletRequest) {
log.info("[执行登录接口]");
String username = data.get("username");
String email = data.get("email");
String phone = data.get("phone");
String password = data.get("password");
List resultList = null;
Map<String, String> map = new HashMap<>();
if(username != null && "".equals(username) == false){
map.put("username", username);
resultList = service.select(map, new HashMap<>()).getResultList();
}
else if(email != null && "".equals(email) == false){
map.put("email", email);
resultList = service.select(map, new HashMap<>()).getResultList();
}
else if(phone != null && "".equals(phone) == false){
map.put("phone", phone);
resultList = service.select(map, new HashMap<>()).getResultList();
}else{
return error(30000, "账号或密码不能为空");
}
if (resultList == null || password == null) {
return error(30000, "账号或密码不能为空");
}
//判断是否有这个用户
if (resultList.size()<=0){
return error(30000,"用户不存在");
}
User byUsername = (User) resultList.get(0);
Map<String, String> groupMap = new HashMap<>();
groupMap.put("name",byUsername.getUserGroup());
List groupList = userGroupService.select(groupMap, new HashMap<>()).getResultList();
if (groupList.size()<1){
return error(30000,"用户组不存在");
}
UserGroup userGroup = (UserGroup) groupList.get(0);
//查询用户审核状态
if (!StringUtils.isEmpty(userGroup.getSourceTable())){
String sql = "select examine_state from "+ userGroup.getSourceTable() +" WHERE user_id = " + byUsername.getUserId();
String res = String.valueOf(service.runCountSql(sql).getSingleResult());
if (res==null){
return error(30000,"用户不存在");
}
if (!res.equals("已通过")){
return error(30000,"该用户审核未通过");
}

首页载入流程：系统先连接数据库，显示界面参数初始化，读取数据库的数据表，读取html显示模板，对数据按添加时间排序，按照模板设计位置显示数据，刷新显示界面，断开数据库连接。
首页如下图所示。
图5-4首页界面
其中载入首页的主要代码如下。
@RequestMapping(value = {"/sum_group", "/sum"})
public Map<String, Object> sum(HttpServletRequest request) {
Query count = service.sum(service.readQuery(request), service.readConfig(request));
return success(count.getResultList());
}
学校提交学生后后台会自动生成学生列表。从session中取出该用户信息，前台发起请求，将对应的学校信息、xueshengpId参数信息从前台传递XueshengController类里，匹配到create()方法，create()方法调用XueshengServiceImpl类的createXuesheng()方法获取数据，调用本类的getCartXueshengItem()方法得到学生列表。
学生录入界面如下所示。

@PostMapping("change_password")
public Map<String, Object> change_password(@RequestBody Map<String, String> data, HttpServletRequest request){
// 根据Token获取UserId
String token = request.getHeader("x-auth-token");
Integer userId = tokenGetUserId(token);
// 根据UserId和旧密码获取用户
Map<String, String> query = new HashMap<>();
String o_password = data.get("o_password");
query.put("user_id" ,String.valueOf(userId));
query.put("password" ,service.encryption(o_password));
Query ret = service.count(query, service.readConfig(request));
List list = ret.getResultList();
Object s = list.get(0);
int count = Integer.parseInt(list.get(0).toString());
if(count > 0){
// 修改密码
Map<String,Object> form = new HashMap<>();
form.put("password",service.encryption(data.get("password")));
service.update(query,service.readConfig(request),form);
return success(1);
}
return error(10000,"密码修改失败！");
}

- 成绩汇总管理模块
-
成绩汇总管理包括新增成绩汇总、删除成绩汇总、修改成绩汇总、查询成绩汇总等，以成绩汇总新增为例，在视图层请求成绩汇总信息新增，反馈后，调用业务逻辑层，通过业务逻辑层的接口调用底层的数据逻辑层完成数据库联动操作。
成绩汇总管理的流程如所示。

成绩汇总信息添加的逻辑代码如下。
public Map<String, Object> getList(HttpServletRequest request) {
Map<String, Object> map = service.selectToPage(service.readQuery(request), service.readConfig(request));
return success(map);
}
管理员发布成绩汇总后，成绩汇总在系统前台显示，浏览成绩汇总信息，包括活动类型、城市、年级、平均分，选择相应的成绩汇总分析，通过id传参，找到该成绩汇总，在chengjihuizongfenxi_add.Java提交分析表单，生成分析记录。
成绩汇总分析流程如下图所示。
图5-13成绩汇总分析流程
成绩汇总分析界面如下图所示。
图5-14成绩汇总分析界面
成绩汇总分析的主要逻辑代码:
@RequestMapping(value = {"/count_group", "/count"})
public Map<String, Object> count(HttpServletRequest request) {
Query count = service.count(service.readQuery(request), service.readConfig(request));
return success(count.getResultList());
}
在这个产品被投入使用前，首先需要进行试用，这是重要的环节。考虑到某个部分的开发没有缺陷情况下，把各种模块拼接，也有一定概率就存在矛盾。这就好比每个人都很独特，但聚在一起就显得杂乱无章，需要保证有默契的配合。对于测试，要看它的各项内容是否契合的原则。若与最初定下的标准有一定程度上的出入，那么就需要做出一些调整，让最终的大方向朝着目标前进。

本次毕业论文的主要是利用Javaweb+Mysql开发一个安全可靠，操作简易，同时具备业务可扩展的线上线下教学模式下成绩分析系统。本文详细的论述了线上线下教学模式下成绩分析系统的设计和开发，本系统的所有事务逻辑都是按照系统的需求分析进行设计的，系统有学校用户和系统管理员两种角色，本系统多处采用了AJAX的异步交互技术，同时它也叫异步交互技术，利用它我们可以让网页的局部进行数据刷新操作，AJAX和传统的数据更新技术大大增加了客户的体验程度，由于是对局部进行操作那么就减少了一些繁琐而又不必要的操作，减轻了服务器对页面解析的负担。
与其他系统相比，本系统有自身的优点，
例如：
（1）创新性强；
（2）业务逻辑性强，安全性高，在一些重要的功能模块需要通过审查之后才可使用；
（3）移植性高，在所有window平台都可使用。
当然也还有很多需要进一步改进的地方：
（1）系统大多数页面都是全局刷新，缺乏局部刷新，这将增加服务器的压力，如果有大量用户在同一时间段操作同一个功能模块，可能会导致查询缓慢；
（2）页面没有经过专业的UI设计，美观程度不及其他市场其他网站系统，有待改善。
