1. 项目背景与核心需求毕业季对于高校就业指导部门来说是个充满挑战的时期。每年这个时候就业数据统计、企业招聘信息管理、学生就业状态跟踪等事务性工作会集中爆发。传统的手工登记和Excel表格管理方式已经无法满足现代高校就业管理的需求这正是我们开发这套毕业就业信息管理系统的初衷。这个系统需要同时满足三类用户的核心需求对于就业指导老师而言系统需要提供企业招聘信息的集中发布与管理平台学生就业状态的实时跟踪与统计功能各类报表的自动生成与导出能力对于应届毕业生来说系统应当支持个人简历的在线填写与维护招聘信息的浏览与筛选面试通知与录用结果的接收而对企业HR用户系统需要实现招聘岗位的在线发布学生简历的筛选与下载面试安排的线上协调2. 技术选型与架构设计2.1 后端技术栈选择我们选择SpringBoot作为后端框架主要基于以下考虑自动配置特性大幅减少了XML配置内嵌Tomcat简化了部署流程丰富的Starter依赖可以快速集成常用组件完善的生态和社区支持数据库选用MySQL 8.0版本主要因为高校信息化系统普遍采用MySQL作为标准完善的ACID特性保证数据一致性JSON字段支持便于存储半结构化数据窗口函数等高级特性方便复杂统计查询持久层采用MyBatis而非JPA的决策点在于需要编写复杂SQL实现各类统计报表已有DBA团队熟悉SQL优化需要精细控制查询性能2.2 前端技术栈选择Vue.js作为前端框架的优势体现在组件化开发模式适合管理系统类项目响应式数据绑定简化状态管理Vue Router实现前端路由控制丰富的UI组件库选择我们最终选用Element UI前后端分离架构的设计要点后端仅提供RESTful API接口前端通过axios进行HTTP通信JWT实现无状态认证跨域问题通过Spring Security配置解决3. 核心功能模块实现3.1 用户认证与权限控制系统采用RBAC基于角色的访问控制模型主要实现步骤数据库设计CREATE TABLE sys_user ( id bigint NOT NULL AUTO_INCREMENT, username varchar(50) NOT NULL, password varchar(100) NOT NULL, salt varchar(20) DEFAULT NULL, real_name varchar(50) DEFAULT NULL, avatar varchar(255) DEFAULT NULL, email varchar(100) DEFAULT NULL, mobile varchar(20) DEFAULT NULL, status tinyint DEFAULT 1, dept_id bigint DEFAULT NULL, create_time datetime DEFAULT NULL, PRIMARY KEY (id), UNIQUE KEY username (username) ); CREATE TABLE sys_role ( id bigint NOT NULL AUTO_INCREMENT, name varchar(50) DEFAULT NULL, remark varchar(100) DEFAULT NULL, create_time datetime DEFAULT NULL, PRIMARY KEY (id) ); CREATE TABLE sys_user_role ( id bigint NOT NULL AUTO_INCREMENT, user_id bigint DEFAULT NULL, role_id bigint DEFAULT NULL, PRIMARY KEY (id) );Spring Security配置核心代码Configuration EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { Autowired private UserDetailsServiceImpl userDetailsService; Override protected void configure(HttpSecurity http) throws Exception { http.csrf().disable() .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS) .and() .authorizeRequests() .antMatchers(/api/auth/**).permitAll() .anyRequest().authenticated(); http.addFilterBefore(jwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class); } Bean public JwtAuthenticationFilter jwtAuthenticationFilter() { return new JwtAuthenticationFilter(); } }3.2 招聘信息管理模块企业HR用户可以通过该模块发布和管理招聘信息核心功能点包括富文本编辑器的集成template div quill-editor v-modelcontent :optionseditorOption bluronEditorBlur focusonEditorFocus / /div /template script import { quillEditor } from vue-quill-editor import quill/dist/quill.core.css import quill/dist/quill.snow.css export default { components: { quillEditor }, data() { return { content: , editorOption: { modules: { toolbar: [ [bold, italic, underline], [{ list: ordered}, { list: bullet }], [link, image] ] } } } } } /script招聘信息检索接口实现RestController RequestMapping(/api/recruitment) public class RecruitmentController { Autowired private RecruitmentService recruitmentService; GetMapping public Result list(RequestParam MapString, Object params) { PageUtils page recruitmentService.queryPage(params); return Result.ok().put(page, page); } } Service public class RecruitmentServiceImpl implements RecruitmentService { Autowired private RecruitmentDao recruitmentDao; Override public PageUtils queryPage(MapString, Object params) { QueryWrapperRecruitmentEntity wrapper new QueryWrapper(); // 职位名称模糊查询 if (params.get(positionName) !
