The front-end part of the system is developed based on the MVVM model, using the B/S model, and the back-end part is developed based on the Java ssm framework.
Front-end part: The front-end framework adopts the popular progressive JavaScript framework Vue.js. Use Vue-Router and Vuex to achieve dynamic routing and global state management, Ajax to achieve front-end and back-end communication, Element UI component library to make the page quickly prototype, and the front-end of the project realizes responsiveness through grid layout, which can be adapted to PC, tablet, mobile, etc. Perfect layout display for different screen sizes.
Back-end part: use ssm as the development framework, and integrate MyBatis, Redis and other related technologies at the same time
MVVM is shorthand for Model-View-ViewModel. It's essentially an improved version of MVC. MVVM is to abstract the state and behavior of the View in it, and let us separate the view UI from the business logic. Of course, ViewModel has already done these things for us. It can take out the data of Model and help deal with the business logic involved in View because of the need to display content. Microsoft's WPF brings new technical experience, such as Silverlight, audio , video , 3D , animation ..., which leads to more detailed and customizable software UI layer. At the same time, at the technical level, WPF also brings new features such as Binding, Dependency Property, Routed Events, Command, DataTemplate, and ControlTemplate. The origin of the MVVM (Model-View-ViewModel) framework is a new type of architectural framework developed and evolved from the application of the MVP (Model-View-Presenter) pattern combined with WPF . It is based on the original MVP framework and incorporates the new features of WPF to cope with the increasingly complex needs of customers.
Mysql has been updated many times, and the functional level has been very rich and perfect. From Mysql4 version to 5 version, a relatively large update has been made, and it has achieved good practical application results in actual commercial use. The latest version of Mysql supports the compression of information, and at the same time, it can also perform encryption to better meet the needs of information security. At the same time, after multiple updates of the system, the mirroring function of the database itself has also been greatly enhanced, the smoothness of operation and ease of use have been greatly improved, and the use and creation of drivers are also more efficient and faster. The biggest change is the optimization of the display of spatial information, which makes it easier to label and calculate coordinates on the application map. The powerful backup function also ensures that users will feel more at ease during the use process, and the supported Office features also support users' self-installation and use. The display form of information has also been greatly updated, and two very useful display areas have been added, one is the information area, which has classified tables and text, and the display of the interface is more refreshing and specific. The second is the information control of the instrument, which can display information in the instrument information area and compare multiple information at the same time, which brings great convenience to the actual use of users.
In the actual implementation process of the online examination system designed in this article, the main reason for choosing the Mysql database is that there will be a large number of databases that are frequently operated during the application and development of the enterprise application system, and the data security requirements It is also very high. Based on these factors, Mysql with a relatively high safety factor was finally selected to store the background data of the online examination system.
The overall structure diagram of the database management system is shown in the figure below.
Figure 2-1 Database structure
-
B/S structure
B/S (Browser/Server) is a more convenient architecture than its predecessor architecture. It uses the Web server to complete the data transfer and exchange. You only need to download the browser as the client, then the work will achieve a "slimming" effect, and there is no need to consider the problem of non-stop installation of software.
SSM is SpringMVVM+Spring+MySQL. These three frameworks have their own unique advantages, so combining them together can create a strong spark. The designer can create a web application program without consuming a lot of effort, and this program also has the characteristics of clear hierarchy, upgrade and update operations will not affect normal use, and allows multiple uses. This composite framework forms a system with a complete structure, powerful functions and a good structure: SpringMVVM separates each plate, Spring makes development more flexible and convenient, allows developers to directly manipulate objects, and divides labor details at each level, and realizes each level. Decoupling makes the code more flexible and streamlined. This framework enables programmers to avoid individual mistakes during the development period that lead to the destruction of the whole, and also to respond to new requirements from customers for the product in the later stage.

- The relationship between the layers of the ssm framework:
Both the DAO layer and the Service layer can be developed independently, and the mutual coupling is very low, so they can be carried out independently. Such a model is especially advantageous in the process of developing large projects.
The Controller and View layers are developed together because of their high coupling, but they can also be developed independently of the first two layers as a whole. In this way, you only need to know the definition of the interface before the layer and the layer, and call the interface to complete the required logic unit application. Everything is very clear and simple.
To develop any system, it is necessary to analyze its feasibility and consider its time and resource constraints, which can reduce the risk of system development. At the same time, after the analysis, not only can manpower be used reasonably, but also the consumption of various resources can be saved. The following three aspects of technology, economy and society will be introduced.
Technical feasibility mainly considers whether the technology used in the current project can meet the requirements, whether it can meet the requirements on equipment, and whether various auxiliary tools can provide assistance. This system uses the Java development language, the debugging is relatively simple, and the current computer hardware configuration can fully meet the development needs, so it is absolutely feasible technically. Software: Because the software development platforms are mature and feasible, they are fast, large in capacity, high in reliability, and low in price, which can fully meet the needs of the system. Using the Java programming language, there are no technical problems.
Both the Myeclipse development platform and the Mysql back-end database used in the system are free development tools. Therefore, the development cost is mainly concentrated in the later promotion and system maintenance. Compared with the higher-cost C/S model, the lower-cost B/S model is also selected, so there is almost no economic problem.
This system is a self-developed system, starting from the crowdsourcing system for convenient and efficient management of curriculum ideological and political resources. So it's also possible socially.
For performance analysis, compared with the traditional management method, the traditional management method uses manual statistics and management of data information with paper and pen, and this method is more troublesome for storing and finding certain data information. With the advent of computer networks, this traditional method is difficult to adapt to the development of the current society. It not only reduces people's work efficiency, but also requires a lot of manpower and material resources, which is relatively high in terms of time and cost. To reduce costs, improve users' work efficiency, and develop a crowdsourcing system for course ideological and political resources based on computer and network technology.
The development and design of the curriculum ideological and political resource crowdsourcing system is an independent system. The previous database is used for data storage and development, mainly to realize the user roles and corresponding functional modules of the curriculum ideological and political resource crowdsourcing system, so that the curriculum ideological and political The management of the resource crowdsourcing system will not have management differences and low efficiency, but is just the opposite of traditional management information. The realization of the curriculum ideological and political resource crowdsourcing system can save resources, and the processing speed of business is also improved. Efficient and powerful.
3.3 System flow analysis
3.3.1 Add information process _
Add information, the numbering system uses the automatic numbering mode, no user fills in, the user adds information and enters the information, the system will automatically confirm the information and data, if the verification is successful, the information is valid and added to the database, if the information is invalid, re-enter the information. Figure 3-3 shows the process of adding information.
Figure 3-3 Flowchart of adding information
3.3.2 Operation process
If the user wants to enter the system, he first enters the system login interface, selects the login type to log in through the correct user name and password, the system will check the login information, the information is correct, and then enter the corresponding function interface, prompting that the information is wrong and the login fails. The system operation process is shown in Figure 3-4.
Figure 3-4 Operation flow chart
3.3.3 Delete information process
The user selects the information to delete and clicks the Delete button. The system prompts whether to delete the information. If the user wants to delete the information, the system will delete the information. System database deletion information. Figure 3-5 shows the flow chart of deleting information.
Figure 3-5 Flow chart of deleting information
An overview design analysis of the system project of the curriculum ideological and political resource crowdsourcing system. The main content includes the specific analysis of the curriculum ideological and political resource crowdsourcing system. The database is designed. The data uses mysql database, and the system design adopts a more humanized The operation design can deal with and give feedback to the error information in the system in time.
The design of the curriculum-based ideological and political resources crowdsourcing system is based on existing computers, which can realize detailed understanding and statistical analysis of user management, received tasks, ideological and political tags, notification management, release of courses, ideological and political tasks, etc. The module relationship diagram established according to the system functional requirements is as follows:
Figure 4-1 Administrator function module diagram
-
- Development process design
The development of the course ideological and political resources crowdsourcing system analyzes the management module and the database used by the system, writes generation development, planning and operation are the necessary three steps to build an information management application program, which determines whether the system can truly realize the preset functions And whether it can be implemented after successful design. In the development process, each stage must be developed in strict accordance with the linear sequence, and each work generated in the corresponding stage can be verified and checked by technology. Make sure that it is correct after the completion of one stage, and will not cause drag and drop phenomenon in the next stage, so that the system can be guaranteed after the design function is completed.
Judging from the successful development experience of the curriculum ideological and political resource crowdsourcing system, the above method has the most obvious effect and minimizes the complexity of system development. As shown in Figure 4-2.
Figure 4-2 Flow chart of the development system
Database is the foundation and core of information system. The quality of database design directly affects the success or failure of information system development. Creating a database table first determines the attributes of entities and the relationships between entities. Create a data table based on the relationship.
4.3.1 Entity ER Diagram
The database is the most important step in the entire software programming. For the database problem, it is mainly to determine the number of databases and the creation of structural formulas. The display system uses Mysql to manage the database to ensure data security and stability.
Conceptual models are designed to abstract real-world information and model the information world. It is a powerful tool for database design. Database conceptual model design can describe the conceptual model of the real world through ER diagrams. An ER diagram of a system shows the links between entities in the system. Moreover, the Mysql database is a database with relatively strong self-protection capabilities. The following figure is mainly an ER diagram of database entities:
(1) Publish the course management ER diagram, as shown in Figure 4-3:
Figure 4-3 Publish course entity property graph
(2) The ER diagram of ideological and political task management is shown in Figure 4-4:
Figure 4-4 Entity Diagram of Ideological and Political Task Management
These functions can fully meet the needs of the curriculum ideological and political resource crowdsourcing system. The function of this system is relatively comprehensive, as shown in Figure 4-5 below the system function structure.

- 发布课程模块的实现
如果发布课程数据的信息需要修改，管理员可以通过查询发布课程数据的基本信息来查询发布课程数据，查询发布课程数据是通过ajax技术来进行查询的，需要传递发布课程数据的标题、编号等参数然后在返回到该页面中,可以选中要修改或删除的那条信息，如果选中了超过一条数据，页面会挑一个窗口提醒只能选择一条数，如果没有选中数据会挑一个窗口题型必须选择一条数据。当选择确认修改的时候，后台会根据传过来的id到数据库查询，并将结果返回到修改页面中，可以在修改页面中修改刚刚选中的信息当点击确认的时候from表单会将修改的数据提交到后台并保存到数据库中，就是说如果提交的数据数据库中存在就修改，否则就保存。
发布课程数据展示界面如下图所示。

- 思政任务模块的实现
此页面的关键是编写思政任务信息，包括思政编号，名称，详情等。单击提交按钮以完成信息的添加。如果未写入完整的思政任务信息，例如，如果未写入思政编号，系统将给出相应的错误提示，并且无法成功输入。数据以概念的形式以onsubmit =“return checkForm（）”的形式写入以进行检查，checkForm（）函数是一种用于写入数据的不同类型的校对方法，是不是为空也是经过form表单中的οnsubmit=”return checkForm()来检查。
管理员点击左侧菜单“思政任务管理”，页面跳转到思政信息管理外观，调用后台测量查询所有课程信息。并将信息密封到数据集合List，绑定到请求对象，然后页面跳转到相应的Java，显示出思政任务信息，单击删除按钮完成思政信息的删除。
思政任务流程图如下图所示。

思政任务界面如下图所示。
图5-1思政任务界面
思政任务管理关键代码如下所示。
@RequestMapping(value = "/del")
@Transactional
public Map<String, Object> del(HttpServletRequest request) {
service.delete(service.readQuery(request), service.readConfig(request));
return success(1);
}
教师在yhzhgl查看教师信息，先使用sql语句查询出所有教师表的数据，然后调用PageManager.getPages(url,4,sql, request )，返回一个ArrayList的对象，在for循环里，使用jsp得到每个ArrayList对象的数据，在jsp页面中解析ArrayList对象，得到其各个键值对的值。
教师用户管理界面如下图所示。
图5-1教师用户界面图
教师用户管理关键代码如下所示。
@RequestMapping("/get_list")
public Map<String, Object> getList(HttpServletRequest request) {
Map<String, Object> map = service.selectToPage(service.readQuery(request), service.readConfig(request));
return success(map);
}
-
- 已接任务管理模块的实现
用户已接任务后后台会自动生成已接列表。从session中取出该用户信息，前台发起请求，将对应的用户信息、baozhangpId参数信息从前台传递BaozhangController类里，匹配到create()方法，create()方法调用BaozhangServiceImpl类的createBaozhang()方法获取数据，调用本类的getCartBaozhangItem()方法得到已接任务列表。
已接任务推荐界面如下所示。
图5-1已接任务界面
已接任务管理关键代码如下：
@RequestMapping(value = "/del")
@Transactional
public Map<String, Object> del(HttpServletRequest request) {
service.delete(service.readQuery(request), service.readConfig(request));
return success(1);
}
-
- 思政标签管理模块的实现
此页面的关键是编写思政标签信息，包括思政标签编号，名称，详情等。单击提交按钮以完成信息的添加。如果未写入完整的思政标签信息，例如，如果未写入思政标签编号，系统将给出相应的错误提示，并且无法成功输入。数据以概念的形式以onsubmit =“return checkForm（）”的形式写入以进行检查，checkForm（）函数是一种用于写入数据的不同类型的校对方法，是不是为空也是经过form表单中的οnsubmit=”return checkForm()来检查。
管理员点击左侧菜单“思政标签管理”，页面跳转到思政标签信息管理外观，调用后台测量查询所有课程信息。并将信息密封到数据集合List，绑定到请求对象，然后页面跳转到相应的Java，显示出思政标签信息，单击删除按钮完成思政标签信息的删除。
思政标签流程图如下图所示。

思政标签添加关键代码如下所示。
public List selectBaseList(String select) {
List<Map<String,Object>> mapList = baseMapper.selectBaseList(select);
List<E> list = new ArrayList<>();
for (Map<String,Object> map:mapList) {
list.add(JSON.parseObject(JSON.toJSONString(map),eClass));
}
return list;
}
-
- 通知管理模块的实现
通知功能整体流程：用户浏览通知信息时，同时会显示通知的状态，系统会在其显示详细信息的页面时便会判断通知的状态，若图书状态为可通知，则会显示通知信息的链接按钮。在用户点击通知按钮时，会先通过拦截器判断用户是否登录，若未登录，会跳转至登录页面，提示用户先登录，若为登录用户就会跳转至填写通知信息的页面，填写好通知信息之后，点击提交按钮，通知成功之后返回提示信息，告知用户通知成功。
通知管理界面如下图所示。
图5-1通知管理界面图
通知管理关键代码如下所示。
public List selectBaseList(String select) {
List<Map<String,Object>> mapList = baseMapper.selectBaseList(select);
List<E> list = new ArrayList<>();
for (Map<String,Object> map:mapList) {
list.add(JSON.parseObject(JSON.toJSONString(map),eClass));
}
return list;

本研究针对课程思政资源众包系统地需求建模，数据建模及过程建模分析设计并实现课程思政资源众包系统的过程。给出系统应用架构并分析优劣势，通过功能分解图，系统组件图描述功能需求。设计建立了数据库，给出系统关键数据结构的定义。通过类关系图描述组件间的协作关系，给出各个类的定义方法。通过描述每一个类的字段，属性及方法实现课程思政资源众包系统 的前后端代码。最终给出系统集成整合方法，完成课程思政资源众包系统 地设计与实现。
在此项目的开发中，先要按照产品经理做出的产品模型铺出大体的页面，并在其中找好页面的逻辑关系，并且中途总结一些页面上的问题重新反馈给产品经理，当静态页面的搭建的大体已经完善时，就需要和负责后台开发的技术开发者联系，来接好前后台的数据接口，可以让后台的信息在前台显示出来，在这个项目实现中，不光明白了前端开发和产品经理的联系，也明白了后台在整个系统中起到了什么作用，因为前后台的连接，用户可以对系统进行操作，可以在输入自己的相关信息后，通过后台加工，完成对数据库的查找、修改、添加，而理解了这些关系与实现的方法后。再去完善整个系统的功能就更加清晰与简单了。此次的项目它涉及了前台与后台系统的搭建，在学校所学的知识基础上，此次的项目，让我对于一个系统的前端开发，以及后台的作用都有了一个更深切的认知。

thank you
On the completion of this thesis, I would like to thank my advisor. In the instructor's web design class, I learned a lot at that time, which laid a certain foundation for my internship process, and the instructor also made many suggestions for my design and gave them careful guidance. I have patiently guided me to improve all the problems, and I have given my friends who wrote papers to encourage me from time to time. In addition, I would like to thank the front-end students who taught me how to improve this project. For this project, I realized it while studying. There are many things to start with. I don't really understand it, but the front-end development students guided me very patiently to complete this project. In the back-end development of the system, the back-end development technology used will also explain to me from time to time, which helps me to better understand the paper. Finished, I would like to express my heartfelt thanks to the classmates who helped me and the instructors who have been teaching me, and I wish you success in your career.
