public static String generateToken(String username) { return Jwts.builder() .setSubject(username) .setIssuedAt(new Date()) .setExpiration(new Date(System.currentTimeMillis() 3600000)) .signWith(SignatureAlgorithm.HS256, SECRET_KEY) .compact(); } }岗位申请流程使用状态机如Spring StateMachine管理申请状态提交、审核、录用。定时任务Scheduled自动关闭过期岗位。数据统计ECharts集成可视化图表后端通过聚合查询提供数据-- 示例月度岗位统计 SELECT DATE_FORMAT(create_time, %Y-%m) AS month, COUNT(*) AS job_count FROM work_study_job GROUP BY month;部署与优化容器化Docker打包应用镜像Kubernetes管理集群可选。性能优化Nginx反向代理和负载均衡。数据库分库分表ShardingSphere应对大规模数据。监控Prometheus Grafana监控系统指标。ELK日志分析。扩展性设计微服务化可选Spring Cloud Alibaba拆分模块用户服务、岗位服务等。RocketMQ处理异步通知如申请结果推送。移动端适配Uniapp跨端开发复用后端API。核心模块设计实体类设计以Student为例Entity Table(name student) public class Student { Id GeneratedValue(strategy GenerationType.IDENTITY) private Long id; Column(nullable false) private String studentId; Column(nullable false) private String name; OneToMany(mappedBy student) private ListWorkRecord workRecords; // getters and setters }岗位申请服务层Service public class JobApplicationServiceImpl implements JobApplicationService { Autowired private JobRepository jobRepository; Transactional public ApplicationResult applyJob(Long studentId, Long jobId) { Job job jobRepository.findById(jobId) .orElseThrow(() - new ResourceNotFoundException(Job not found)); if (job.getCurrentApplications() job.getMaxApplications()) { return new ApplicationResult(false, Position already filled); } job.setCurrentApplications(job.getCurrentApplications() 1); jobRepository.save(job); return new ApplicationResult(true, Application successful); } }RESTful API 实现岗位管理控制器RestController RequestMapping(/api/jobs) public class JobController { Autowired private JobService jobService; GetMapping public ResponseEntityListJobDTO getAllJobs( RequestParam(required false) String department, PageableDefault(size 10) Pageable pageable) { PageJobDTO jobs jobService.findJobs(department, pageable); return ResponseEntity.ok() .header(X-Total-Count, String.valueOf(jobs.getTotalElements())) .body(jobs.getContent()); } PostMapping PreAuthorize(hasRole(ADMIN)) public ResponseEntityJobDTO createJob(Valid RequestBody JobCreateRequest request) { JobDTO created jobService.createJob(request); return ResponseEntity.status(HttpStatus.CREATED).body(created); } }薪资计算逻辑薪资计算服务Service public class SalaryCalculationService { private static final BigDecimal BASE_RATE new BigDecimal(15.00); public BigDecimal calculateSalary(WorkRecord record) { BigDecimal hours new BigDecimal(record.getWorkHours()); BigDecimal rate BASE_RATE; if (record.getJob().getCategory() JobCategory.TECHNICAL) { rate rate.add(new BigDecimal(5.00)); } return hours.multiply(rate) .setScale(2, RoundingMode.HALF_UP); } }安全配置Spring Security配置Configuration EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { Override protected void configure(HttpSecurity http) throws Exception { http.csrf().disable() .authorizeRequests() .antMatchers(/api/auth/**).permitAll() .antMatchers(/api/admin/**).hasRole(ADMIN) .antMatchers(/api/student/**).hasRole(STUDENT) .anyRequest().authenticated() .and() .addFilter(new JWTAuthenticationFilter(authenticationManager())) .addFilter(new JWTAuthorizationFilter(authenticationManager())) .sessionManagement() .sessionCreationPolicy(SessionCreationPolicy.STATELESS); } }数据持久层自定义查询方法public interface WorkRecordRepository extends JpaRepositoryWorkRecord, Long { Query(SELECT wr FROM WorkRecord wr WHERE wr.student.id :studentId AND wr.status APPROVED) ListWorkRecord findApprovedRecordsByStudent(Param(studentId) Long studentId); Query(value SELECT * FROM work_record WHERE work_date BETWEEN :start AND :end, nativeQuery true) PageWorkRecord findByDateRange( Param(start) LocalDate start, Param(end) LocalDate end, Pageable pageable); }异常处理全局异常处理器ControllerAdvice public class GlobalExceptionHandler { ExceptionHandler(ResourceNotFoundException.class) public ResponseEntityErrorResponse handleNotFound(ResourceNotFoundException ex) { ErrorResponse response new ErrorResponse( HttpStatus.NOT_FOUND.value(), ex.getMessage(), System.currentTimeMillis()); return ResponseEntity.status(HttpStatus.NOT_FOUND).body(response); } ExceptionHandler(MethodArgumentNotValidException.class) public ResponseEntityErrorResponse handleValidation(MethodArgumentNotValidException ex) { ListString errors ex.getBindingResult() .getFieldErrors() .stream() .map(FieldError::getDefaultMessage) .collect(Collectors.toList()); ErrorResponse response new ErrorResponse( HttpStatus.BAD_REQUEST.value(), Validation failed, System.currentTimeMillis(), errors); return ResponseEntity.badRequest().body(response); } }
