1 Introduction

1.1Research background _

Personnel management system, which simply refers to the collection of advanced human resource management concepts, human resource management practices, and experience in building human resources information systems from successful companies, uses information technology to achieve highly integrated management of corporate human resource information, and is used by Chinese companies human resources management solutions. The core value lies in liberating human resources workers from the tedious daily chores, allowing them to devote more energy to the enterprise's human resources function management and management decision-making, so as to maintain the company's continuous and efficient operations. Centrally record, monitor and analyze all workforce skills and qualifications to provide decision analysis. Improve the overall scientific and technological content and management efficiency of the enterprise, and accelerate the informatization construction of the enterprise.

The history of the personnel management system can be traced back to the 1960s. Since computer applications were not yet popular at that time, the personnel management system could only complete simple salary accounting work and did not involve personnel information management other than salary calculation. However, with the rapid development of computer technology and the popularization of computers in enterprise management, it is imperative to use computers to realize enterprise personnel management. For large and medium-sized enterprises, the use of computers to support the enterprise in completing daily labor and personnel management tasks efficiently is a necessary condition to adapt to the requirements of modern enterprise systems and promote enterprise labor and personnel management to become scientific and standardized; it has advantages that computer management cannot match. Fast, easy to find, high reliability, large storage capacity, good confidentiality, long life, low cost, etc. These advantages can greatly improve the efficiency of personnel management, and are also important conditions for the scientific and formal management of enterprises and their integration with the world. Different enterprises have different personnel management systems, which determines the design of different personnel management systems according to the needs of different enterprises, so as to better serve the enterprise and bring higher economic benefits to the enterprise.

1.2 Research status

At present, the development technology of domestic personnel management information systems has become relatively mature. This is because personnel management has a wide application field and is involved in all walks of life. The business is clear and the needs are clear. There is no need for too many complex processes in the design and implementation of the project, but if it is a personnel management system with complete functions and practical usability, careful analysis and design are required.

Our country's management information system was initially introduced from developed countries such as the United States. Mature enterprise management systems such as EPR also originated in the United States. Enterprise personnel management systems belong to the category of management information systems. Our country's start in this area lags behind that of Western developed countries. . Although Chinese companies have successively developed many excellent management information systems, overall, their quality still has a lot of room for improvement compared with developed countries.

1.3 Characteristics of system development technology

(1) The backend of the web background management in the personnel management system no longer uses the ancient jsp+javabean+servlet technology, but uses the current mainstream ssm framework, which reduces java configuration code and simplifies programming code. The current ssm framework also One of the frameworks chosen by many companies.

(2) The front-end of the web background management in the personnel management system uses a JavaScript framework, which can beautify the page design in conjunction with ajax[8] and jquery[9].

(3) The popular vue framework combines jQuery technology, extends some plug-ins on the basis of jQuery, and better realizes front-end design by defining plug-ins by yourself.

(4) The database in the personnel management system uses mysql5.7, which has high execution efficiency.

2 Analysis of Personnel Management System

System analysis is a prerequisite for developing a project. Through system analysis, the basic needs of the main users of the system can be well understood, and this is also the reason for the development of the project. Then, a feasibility analysis is performed on the system development, which usually includes technical feasibility, economic feasibility, etc. The feasibility analysis is also an analysis from the overall perspective of the project. Then the specific requirements of the project are analyzed. The analysis method is generally implemented through the user's use case diagram. The following is a detailed introduction.

2.1 Feasibility analysis

(1) Technical feasibility analysis

The personnel management system uses the MySQL database for storage and development tools such as IDEA and Tomcat for development, which can bring a lot of convenience to our writing work. The system is developed using the SSM framework, which makes the system more scalable and maintainable, reduces Java configuration code, and simplifies programming code. Currently, the SSM framework is also one of the frameworks chosen by many enterprises.

(2) Economic feasibility analysis

The development software used in developing the personnel management system, such as IDEA development tools, Tomcat8.0 server, MySQL5.7 database, Photoshop image processing software, etc., are all open source and free. These environments have been systematically studied in school. You can operate it independently without any additional cost, and the system development tools can be downloaded directly from the Internet, so it is economically feasible.

(3) Operation feasibility analysis

When designing this project, I referred to many successful cases of similar systems, systematically analyzed their operation interfaces and functions, and combined many cases together to highlight people-oriented and simplified operations, so people with basic computer knowledge can Operate this project. Therefore, there is no problem with operational feasibility.

2.2 System business process analysis

The workflow under administrator authority is mainly as follows: the administrator provides a login button through the system interface and clicks it to transfer to the administrator login interface, and fills in the corresponding administrator account and administrator password on the interface to enter the system under administrator authority. The background system has set up corresponding operation functions on the left navigation bar of the system.

The workflow under user permissions is mainly as follows: the user authenticates and registers through the registration function provided by the system, then performs personal identity verification on the login interface, enters the user's personal backend interface, and performs corresponding operations.

The business process of the personnel management system is shown in the figure below.

Figure 3-3 System business flow chart

2.5 Summary of this chapter

This chapter mainly determines the functions to be realized by the entire personnel management system through feasibility analysis, process analysis, functional requirements analysis, and system use case analysis of the personnel management system. It also provides standards for code implementation and testing of personnel management systems.

3 Overall design of personnel management system

The main contents discussed in this chapter include the functional module design and database system design of the personnel management system.

3.1 System architecture design

This personnel management system is divided into three layers in terms of architecture: presentation layer (UI), business logic layer (BLL) and data layer (DL).

Figure 3-1 Personnel management system architecture design diagram

Presentation layer (UI): Also known as the UI layer, it mainly completes the UI interaction function of the personnel management system. A good UI can improve the user experience and enhance the user's comfort when using the personnel management system. The interface design of the UI must also adapt to different versions of personnel management systems and different size resolutions to achieve good compatibility. The UI interaction function requirements are reasonable, and users must obtain consistent interaction results when performing interactive operations. This requires the presentation layer to be well connected with the business logic layer.

Business logic layer (BLL): mainly completes the data processing function of this personnel management system. The data transmitted by the user from the presentation layer is processed by the business logic layer and delivered to the data layer. The data read by the system from the data layer is processed by the business logic layer and delivered to the presentation layer.

Data layer (DL): Since the data of this personnel management system is placed in the mysql database on the server side, the part that belongs to the service layer can be directly integrated into the business logic layer. Therefore, there is only the database in the data layer, which mainly completes my personnel management. Management system's data storage and management functions.

3.4本章小结

整个人事管理系统的需求分析主要对系统总体架构以及功能模块的设计，通过建立E-R模型和数据库逻辑系统设计完成了数据库系统设计。

4 关键模块的设计与实现

4.1登录模块

将首页的左边的功能设计为用户登录的位置，所以在进行登录的地方就会显示首页。在登录后就是大众较为熟悉的位置，也就是让用户进行账号以及密码输入的样式。

当用户输入完信息并点击登录按钮时，Struts就会将用户输入的信息传递进表单并装入相应的对象之中，然后再转到相应位置进行校验。若用户名和密码框都是空的，那么系统就会不可将账号密码均设置为空值。

系统的底层设置要求账号密码不可以都是空值，将这些信息传递给相关的类中的对象方法并调用相关的信息，对于用户输入的数据进行检验。若检验结果正确会自动转到系统首页欢迎页面，如果不正确系统就会返回用户登录界面。

用户登录流程图如下所示。

图4.1用户登录流程

系统登录界面如下图所示。

图4.1　登录界面图

登录关键代码如下所示。

/**

* 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{

4.2注册模块

人事管理系统的注册登录操作，用户都是从同一个注册登录页面进行注册登录，若是还未有系统账号，则进行注册操作；若是已注册账号，则用户在操作时，输入账号、密码，再选择相应的角色，如“管理员”、“用户”等。

用户注册流程图如下所示。

图4.2用户注册流程

用户注册界面如下图所示。

图4.2 注册界面图

注册关键代码如下所示。

/**

* 注册

* @return

@PostMapping("register")

public Map<String, Object> signUp(HttpServletRequest request) throws IOException {

// 查询用户

Map<String, String> query = new HashMap<>();

Map<String,Object> map = service.readBody(request.getReader());

query.put("username",String.valueOf(map.get("username")));

List list = service.selectBaseList(service.select(query, new HashMap<>()));

if (list.size()>0){

return error(30000, "用户已存在");

}

map.put("password",service.encryption(String.valueOf(map.get("password"))));

service.insert(map);

return success(1);

}

public Map<String,Object> readBody(BufferedReader reader){

BufferedReader br = null;

StringBuilder sb = new StringBuilder("");

try{

br = reader;

String str;

while ((str = br.readLine()) != null){

sb.append(str);

}

br.close();

String json = sb.toString();

return JSONObject.parseObject(json, Map.class);

}catch (IOException e){

e.printStackTrace();

}finally{

if (null != br){

try{

br.close();

}catch (IOException e){

e.printStackTrace();

}

return null;

}

5系统测试

5.1系统测试的目的

系统开发到了最后一个阶段那就是系统测试，系统测试对软件的开发其实是非常有必要的。因为没什么系统一经开发出来就可能会尽善尽美，再厉害的系统开发工程师也会在系统开发的时候出现纰漏，系统测试能够较好的改正一些bug，为后期系统的维护性提供很好的支持。通过系统测试，开发人员也可以建立自己对系统的信心，为后期的系统版本的跟新提供支持。

5.2 系统测试用例

实际结果	实际结果与预期结果一致

5.3 系统测试结果

通过编写人事管理系统的测试用例，已经检测完毕用户登录模块、员工信息查看模块、员工信息添加模块、员工信息搜索模块、密码修改功能测试，通过这5大模块为人事管理系统的后期推广运营提供了强力的技术支撑。

结论

至此，人事管理系统已经结束，在开发前做了许多的准备，在本系统的设计和开发过程中阅览和学习了许多文献资料，从中我也收获了很多宝贵的方法和设计思路，对系统的开发也起到了很重要的作用，系统的开发技术选用的都是自己比较熟悉的，比如Web、ssm技术、MYSQL，这些技术都是在以前的学习中学到了，其中许多的设计思路和方法都是在以前不断地学习中摸索出来的经验，其实对于我们来说工作量还是比较大的，但是正是由于之前的积累与准备，才能顺利的完成这个项目，由此看来，积累经验跟做好准备是十分重要的事情。

当然在该系统的设计与实现的过程中也离不开老师以及同学们的帮助，正是因为他们的指导与帮助，我才能够成功的在预期内完成了这个系统。同时在这个过程当中我也收获了很多东西，此系统也有需要改进的地方，但是由于专业知识的浅薄，并不能做到十分完美，希望以后有机会可以让其真正的投入到使用之中。

致谢

逝者如斯夫，不舍昼夜。转眼间，大用户用户活便已经接近尾声，人面对着离别与结束，总是充满着不舍与茫然，我亦如此，仍记得那年秋天，我迫不及待的提前一天到了学校，面对学校巍峨的大门，我心里充满了期待：这里，就是我新生活的起点吗？那天，阳光明媚，学校的欢迎仪式很热烈，我面对着一个个对着我微笑的同学，仿佛一缕缕阳光透过胸口照进了我心里，同时，在那天我认识可爱的室友，我们携手共同度过了这难忘的两年。如今，我望着这篇论文的致谢，不禁又要问自己：现在，我们就要说再见了吗？

感慨莫名，不知所言。遥想当初刚来学校的时候，心里总是想着工科学校会过于板正，会缺乏一些柔情，当时心里甚至有一点点排斥，但是随着我对学校的慢慢认识与了解，我才认识到了她的美丽，她的柔情，并且慢慢的喜欢上了这个校园，但是时间太快了，快到我还没有好好体会她的美丽便要离开了，但是她带给我的回忆，永远不会离开我，也许真正离开那天我的眼里会满含泪水，我不是因为难过，我只是想将她的样子映在我的泪水里，刻在我的心里。最后，感谢我的老师们，是你们教授了我们知识与做人的道理；感谢我的室友们，是你们陪伴了我如此之久；感谢每位关心与支持我的人。

少年，追风赶月莫停留，平荒尽处是春山。
