With the rapid development of computer, network and communication technology, the rapid development of the Internet has become an irresistible trend in today's society. The level of information is an important indicator of the degree of modernization of a country and society. The processing and utilization of information is the standard for measuring a country's economic development level and scientific and technological level. Talent is the key to the development of any industry. College students are synonymous with talents. How to recruit students with real talents is a concern of all enterprises. But they can't find ideal jobs, and they can't use their talents, which makes college students worry. The first category they enter society is work, and when it comes to job hunting, job fairs are probably the first thing most people think of. Although the job fair is one of the main ways to exchange talents, it is far from meeting the needs of reality.
For a limited time, the job fair is a face-to-face communication with college students. Although some job fairs are released in advance or other publicity methods, there are still many companies and college students who pass by, and some people have to give up some important things to participate in the job fair. Due to the large number of people participating in the job fair and the fluidity of the entire process, management is very difficult. There will be plenty of job fairs and limited booths. It is very difficult for businesses to meet students one by one, so human resources cannot be better allocated. In the real society, there is an urgent need for third parties to bridge the gap between enterprises and talents, and to make up for various deficiencies in recruitment. Under this condition, closely combining network advantages with recruitment, job fairs are developed.
With the advent of the network information age, online recruitment as a new form of recruitment has risen rapidly, and has quickly been supported and applied by most job fair participants and employers. The advantages of online recruitment are first reflected in providing a platform for mutual communication between job fair attendees and employers. The rise of online recruitment is also a big change in the concept and method of job fairs and recruitment compared with the past. With the rapid development of the Internet, the number of Internet users in China has grown rapidly, and the number of online recruiting users has also increased.
51job, Zhonghua Yingcai and Zhaopin are known as the three giants of China's online recruitment. Data show that the market revenue share of the three major recruitment websites reached 61.6%. Although the number and revenue scale of other industry-based, search-type, and social-type websites have increased, it is difficult to shake the online recruitment status of these three giants in the short term.
The needs of recruiting companies for information release, brand promotion, resume screening, and personnel initial test arrangement determine that subdividing recruitment websites will be the future development trend.
Compared with foreign employment systems, there is a big gap in professional marketing and telemarketing, template processing of personalized resumes, industry segmentation, full use of address books, and localized services. It can provide value-added services that satisfy customers. Like Monster, the income of its individual members even accounts for one-third of the total income, and domestic online recruitment companies can fully tap the potential from the existing scale.
It is foreseeable in the future that online recruitment will be further subdivided, and a powerful weapon to surpass homogeneous competition is to find market segments for specialized services. Online recruitment companies that are subdivided into regions and industries will have greater opportunities. They can get closer to users and provide localized services.
The front-end framework of this system adopts 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, and Element UI component library to make the page quickly form. Back-end part: use springboot as the development framework, and integrate MyBatis, Redis and other related technologies at the same time.
The Java computer programming language itself is different from the traditional C++ computer programming language. It is very simple and can be learned quickly. As an object-oriented language, its main features are:
Its basic unit is the object, and the object contains properties and methods. Properties are used to describe objects, and methods are used to manipulate objects.
The software program written can be run and used on any computer without limitation due to different software and hardware conditions.
In an application program, two or more threads can exist at the same time, and these multiple threads can run concurrently, which saves time and improves software performance at the same time.
HTML is a commonly used language for making web pages, and it is generally used to make static pages. Its commands can reflect text information, link information, graphic information and table information, etc. It is now widely accepted and widely used on the Internet [5].

- MVVM mode
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.
Now the MySQL database can support many users on the network, and it can also adapt to the deployment or configuration of customer service machines and servers. Our server and client machines here are actually a software concept, and the computer hardware we use is also There is no one-to-one correspondence with them [3].
MySQL is a very popular relational database management system, and its appearance has always been a leader. It is not only very powerful, but also very convenient to use, and 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, and manages the database 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 [4].
Advantage 1: In MySQL, users with different identities are set with different permissions to complete different business logics, which makes MySQL far exceed other relational databases in terms of security and integrity.
Advantage 2: MySQL can also support the data types of animation, graphics and sound, which shows that MySQL can also support multiple data types.
Advantage 3: MySQL can also be developed on multiple platforms, and various programming languages for software development can realize the operation of MySQL database [5] [6].
In terms of technology, the current mainstream springboot framework is used to build the main framework of the system. The front desk uses jquery and ajax to realize the design and aesthetic adjustment of the front page. The above technologies are all learned systematically by myself and practiced in course design It can make development more convenient and systematic. From a technical point of view, this system is completely achievable.
In terms of practicability, the main tasks of this design are the homepage, homepage, site management (carousel map), user management (administrators, students, teachers, enterprise users) content management (news list, news classification list) in the college student employment management system. ) More management (message wall, notification announcement, recruitment information, resume information, student job province, contract agreement, enterprise information, interview information, industry management), etc., in line with the current trend of development. From the perspective of users, while also considering system operating costs and human resources, it adopts a convenient way on the Internet to realize online business, making the business process more systematic and more convenient for user experience, which is more practical.
In terms of economy, the main purpose of the college student employment management system designed in this project is to conduct information query management and retrieval services more conveniently and quickly, that is, information software that can be directly put into use. The main cost of the system is mainly concentrated on the operation of continuous maintenance and management update of the used data in the later period. However, once the system is put into actual operation and use, it can improve the efficiency of information query and retrieval. At the same time, it is also necessary to effectively ensure the security of the information of the inquirer. At the same time, the practical application brought by the employment management system for college students The value of this aspect far exceeds the cost of developing and maintaining the actual system. Therefore, it is economically feasible to develop this software.
The functions of the college student employment management system are mainly divided into front-end users registering and logging in according to their own needs, browsing job information and applying for selected jobs. Background system administrators are divided into ordinary administrators and super administrators due to different responsibilities. Ordinary administrators mainly process application forms, while super administrators mainly process registered users, employment information, information classification lists, and employment information.
The system use case diagram is shown below.
Figure 3-1 System use case diagram
The first thing to consider is the system function software. In terms of specific design, whether it can better meet the basic functional requirements of various users. If it cannot better meet the needs of users, then the existence of this system is worthless. The non-functional analysis of the software system is carried out from 7 aspects, one is performance analysis, which is aimed at the system; one is security analysis, which is aimed at the system; the other is integrity analysis, which is aimed at the system; It is scalability analysis, for the system, and the other is performance analysis to adapt to the business. In the face of the comprehensive comparison and analysis of the performance, security, expansion, and integrity of the seven aspects of the employment management system for college students, it is found that the corresponding non-functional requirements analysis is needed.
Security is very important to every system. A system with good security can protect enterprise information and user information from being stolen. Improving the security of the system is not only the responsibility of the user, but also the responsibility of the enterprise. Especially for the employment management system of college students, there must be good security to protect the entire system.
The system has authority control for users, and limits the authority of users according to the role barriers, so as to ensure the security of the system.
The data in the database is input from the outside world. When the data is input, due to various reasons, the input data will be invalid or dirty. Therefore, how to ensure that the input data conforms to the regulations has become the primary concern of database systems, especially multi-user relational database systems.
Therefore, when writing to the database, data integrity, correctness, and consistency must be guaranteed.
Analyze the data flow of the system, and the users of the system are divided into two categories, general users and administrators. The system mainly processes interface information transmission, login information verification, registration information reception, and user response to various operations.
The top-level data flow diagram of the system is shown in the figure below.
Figure 3-2 Top-level data flow diagram
The architecture design of the undergraduate employment management system is mainly divided into three layers, mainly including the Web layer, the business layer, and the Model layer. The web layer also includes the View layer and the Controller layer, and the Model layer includes the metadata extension layer and the data access layer.
The system architecture is shown in the figure below.
Figure 4-1 System architecture
The college student employment management system is generally divided into former student module, enterprise module, teacher module and administrator module.
The four modules appear to exist independently, but the accessed database is the same. The function of each module is made according to the previously completed demand analysis, and after consulting relevant materials.
To sum up, the functional structure diagram of the system is shown in the figure below.
Figure 4-2 System function structure diagram
According to the previous data flow chart, combined with the functional module design of the system, design each information entity that conforms to the system.
The ER diagram of the system is shown in the figure below.
Figure 4-3 System ER diagram
The data tables owned by the college student employment management system are as follows: user information table, job information table, student resume table, and enterprise information table.
Due to the large number of data tables, only the main data tables of the system are displayed, as shown in the following table.

该系统是通过jdbc和MySQL达成连接的，新建一个jdbc.properties文件来填写与数据库连接所需要的驱动和参数。
jdbc.driverClass=com.MySQL.jdbc.Driver
jdbc.url=jdbc:MySQL://localhost:3306/tsi
jdbc.username=root
jdbc.password=123
第一个参数代表MySQL数据库的驱动，第二个参数代表要连接的数据库，第三个和第四个参数代表数据库连接名和密码。
后台与数据库访问主要是通过HQL语句来进行查询的，查询语句中的表名是表格的实体类名，在这种查询语句中*是不允许使用的，除非适合聚合函数一起使用才可以。
用户在填写数据的时候必须与注册页面上的验证相匹配否则会注册失败，注册页面的表单验证是通过JavaScript进行验证的，用户名的长度必须在6到18之间，邮箱必须带有@符号，密码和密码确认必须相同，你输入的密码，系统会根据你输入密码的强度给出指定的值，电话号码和身份证号码必须要求输入格式与生活相符合，当你前台验证通过的时候你点击注册，表单会将你输入的值通过name值传递给后台并保存到数据库中。
用户注册流程图如下图所示。

测试存在于软件开发进程中的最后一个阶段，它可以保证一个软件的开发质量是否符合设计者的初衷，也为程序的正式上线做了最后一道质量检测的工序。软件测试主要是控制各种条件、包括软件输出方式，使用模式和运行环境等，来评估一个系统或应用是否符合设计标准。在软件测试过程中，我们一般刻意的去制造错误和极端条件，不能仅依照正常模式允许，而是多去尝试那些意外的情况。
只有在运行和维护阶段之前经历大量的测试的软件，才能说明它的质量是经得起检验的。最近计算机业界也都一致认为，测试应该存在于软件设计的每个阶段，因为越早发现错误，修复起来就越容易。
实际上，对于一个软件应用，错误是必然存在的，无论使用何种技术或手段，都不可能绝对的排除软件漏洞。测试是随着软件开发一同诞生的，两者是共同发展进步的。实际上，测试可以大幅度的降低维护的成本，如果一个漏洞在开发的早期就被发现，那么修复它的成本远比上线后再修复的成本要低得多。
测试有白盒测试和黑盒测试两种方式。
其中，白盒测试是将软件看成一个透明的白盒子，按照程序的内部控制结构和处理技术逻辑来选定测试用例、软件系统测试的逻辑路径及过程需要进行管理测试，又称玻璃盒测试。因此白盒测试需要选择足够多的测试用例，覆盖尽可能多的代码来发现程序中的错误。
黑盒测试，也称为功能测试。它将需软件看作一个黑盒，像一个普通用户一样来模拟软件的使用流程。黑盒测试通过大量的输入边界值或错误数据，来检查是否可产生正确的输出。
本系统测试 主要选择黑盒测试，少量采用白盒测试。通过测试达到以下测试目的：
1.检查各大功能模块的运行，确保其能够正确运行，并检查各页面的完整性，保证页面完整。
2.检查各个接口是否可以正确地输入和输出，保证数据流通稳定可行。
3.检查数据结构，保证其和外部接口没有访问错误，访问顺利。
4.检查原计划的性能需求有没有完成，运行流畅。

随着计算机互联网技术的迅猛发展，各行各业都已经实现采用计算机相关技术对日益放大的数据进行管理。该课题是大学生就业管理系统为核心展开的，主要是为了实现应届毕业生就业信息化管理和用户在线投递简历的需求。
大学生就业管理系统的开发是以Java编程语言作为基础，在Myeclipse平台上完成编码工作，系统整体为B/S架构，数据库系统使用MySQL。文中详细分析了大学生就业管理系统的研究背景、研究目的和意义、开发工具和相关技术以及系统需求、系统详细设计和系统测试等等一系列内容。系统实现了大学生就业管理系统所需的一些基本功能，并通过测试对这些实现的功能进行了完善，进而提高了系统整体的实用性。整个系统的开发过程中大量使用了Java相关的知识以及前端开发使用的html和javascript等，同时涉及到了很多开源框架和组件，例如后台系统中运用的MVC架构、Freemarker模板引擎等，前端运用的UI框架等。
系统投入运行时，各功能均运行正常。系统的每个界面的操作符合常规逻辑，对使用者来说操作简单，界面友好。整个系统的各个功能设计合理，体现了人性化。
但是由于自己在系统开发过程中对一些用到的相关知识和技术掌握不够牢固，再加上自身开发经验欠缺，因此系统在有些方面的功能还不够完善，考虑的不够全面，因此整个系统还有待日后逐步完善。

This design took 3 months. In this graduation project, it is inseparable from the guidance of the instructor to make things go smoothly. The instructor has given me a lot of help both in the graduation design experience and in the completion of the thesis. On the other hand, I have benefited a lot from the teacher's serious and responsible work attitude, prudent teaching spirit and strong theoretical level. His diligent and cautious attitude towards teaching and educating people also left me with a particularly deep feeling. I have learned a lot from my teachers. In theory and practice, my skills have been greatly improved. Here, I would like to express my heartfelt gratitude to the teachers.
After all the research and development of this graduation project, my system research and development has experienced a special progress from requirement analysis to realization of detailed functions, to final testing and maintenance. Let me have a deeper understanding of system development. Now my hands-on ability and ability to deal with doubts alone have also gained a particularly large increase in practice and learning. This is the best harvest of this graduation project.
Finally, during the whole system development process, the classmates and friends around me gave me a lot of opinions, so I quickly confirmed the business idea of the system. Here, I sincerely express my gratitude to them.
