GetMapping(/search) public ResponseEntityListTutor searchTutors(RequestParam String subject) { return ResponseEntity.ok(tutorService.findBySubject(subject)); } }Vue 组件调用 APIexport default { methods: { async fetchTutors() { const res await axios.get(/api/tutor/search, { params: { subject: Math } }); this.tutors res.data; } } }此技术栈平衡开发效率与系统性能可根据团队熟悉度调整具体工具如用Thymeleaf替代前后端分离。关键点在于模块化设计便于后续扩展功能模块如支付集成、数据分析。核心模块设计实体类设计以家教信息为例Entity Table(name tutor_info) public class TutorInfo { Id GeneratedValue(strategy GenerationType.IDENTITY) private Long id; private String subject; private String gradeLevel; private BigDecimal pricePerHour; ManyToOne JoinColumn(name teacher_id) private User teacher; // getters and setters }数据访问层实现JPA Repository接口public interface TutorInfoRepository extends JpaRepositoryTutorInfo, Long { ListTutorInfo findBySubjectContaining(String keyword); ListTutorInfo findByGradeLevel(String gradeLevel); ListTutorInfo findByPricePerHourBetween(BigDecimal min, BigDecimal max); }服务层实现家教信息服务实现Service Transactional public class TutorInfoServiceImpl implements TutorInfoService { Autowired private TutorInfoRepository tutorInfoRepository; public PageTutorInfo searchTutors(String keyword, String grade, BigDecimal minPrice, BigDecimal maxPrice, Pageable pageable) { SpecificationTutorInfo spec Specification.where(null); if (StringUtils.hasText(keyword)) { spec spec.and((root, query, cb) - cb.like(root.get(subject), % keyword %)); } if (StringUtils.hasText(grade)) { spec spec.and((root, query, cb) - cb.equal(root.get(gradeLevel), grade)); } if (minPrice ! null maxPrice ! null) { spec spec.and((root, query, cb) - cb.between(root.get(pricePerHour), minPrice, maxPrice)); } return tutorInfoRepository.findAll(spec, pageable); } }控制器层实现REST API控制器RestController RequestMapping(/api/tutors) public class TutorInfoController { Autowired private TutorInfoService tutorInfoService; GetMapping public ResponseEntityPageTutorInfo searchTutors( RequestParam(required false) String keyword, RequestParam(required false) String grade, RequestParam(required false) BigDecimal minPrice, RequestParam(required false) BigDecimal maxPrice, Pageable pageable) { PageTutorInfo result tutorInfoService.searchTutors( keyword, grade, minPrice, maxPrice, pageable); return ResponseEntity.ok(result); } }安全配置Spring Security配置Configuration EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers(/api/auth/**).permitAll() .antMatchers(/api/tutors/**).permitAll() .antMatchers(/api/orders/**).authenticated() .and() .csrf().disable() .sessionManagement() .sessionCreationPolicy(SessionCreationPolicy.STATELESS) .and() .addFilterBefore(jwtFilter, UsernamePasswordAuthenticationFilter.class); } }预约功能实现预约服务核心逻辑Service public class OrderServiceImpl implements OrderService { Transactional public Order createOrder(Long tutorInfoId, Long studentId, LocalDateTime startTime, Integer hours) { TutorInfo tutorInfo tutorInfoRepository.findById(tutorInfoId) .orElseThrow(() - new ResourceNotFoundException(Tutor not found)); User student userRepository.findById(studentId) .orElseThrow(() - new ResourceNotFoundException(Student not found)); Order order new Order(); order.setTutorInfo(tutorInfo); order.setStudent(student); order.setStartTime(startTime); order.setHours(hours); order.setTotalAmount(tutorInfo.getPricePerHour().multiply(BigDecimal.valueOf(hours))); order.setStatus(OrderStatus.PENDING); return orderRepository.save(order); } }前端交互示例Vue.js组件方法methods: { async searchTutors() { const params { keyword: this.searchKeyword, grade: this.selectedGrade, minPrice: this.priceRange[0], maxPrice: this.priceRange[1], page: this.pagination.currentPage - 1, size: this.pagination.pageSize }; const response await axios.get(/api/tutors, { params }); this.tutors response.data.content; this.pagination.total response.data.totalElements; } }数据库设计校园家教信息平台的数据库设计需要涵盖用户信息、家教需求、订单管理、评价系统等核心模块。以下为关键表结构设计用户表useruser_id主键自增username用户名唯一password加密存储role角色学生/教师/管理员phone联系方式avatar头像URL家教信息表tutor_infotutor_id主键关联用户IDsubject教授科目如数学、英语grade_range授课年级范围price课时费description个人简介certificate资质证明URL需求表demanddemand_id主键自增student_id关联学生用户IDsubject需求科目grade年级要求budget预算范围status状态未接单/已匹配订单表orderorder_id主键UUIDtutor_id关联教师IDdemand_id关联需求IDstart_time授课开始时间duration课时长分钟payment_status支付状态评价表reviewreview_id主键自增order_id关联订单rating评分1-5星comment文字评价anonymous是否匿名系统开发实现采用Spring Boot MyBatis Plus框架组合分层架构设计实体类示例JPA注解Entity Table(name tutor_info) public class TutorInfo { Id GeneratedValue(strategy GenerationType.IDENTITY) private Long tutorId;

if (!PENDING.equals(demand.getStatus())) { throw new BusinessException(需求已被接单); } demand.setStatus(MATCHED); demandRepository.save(demand); Order order new Order(); order.setOrderId(UUID.randomUUID().toString()); order.setTutorId(tutorId); order.setDemandId(demandId); return orderRepository.save(order); } }API接口设计RestController RequestMapping(/api/demands) public class DemandController { PostMapping public ResponseResult createDemand(Valid RequestBody DemandCreateDTO dto) { return ResponseResult.success(demandService.createDemand(dto)); } GetMapping(/{id}) public ResponseResult getDemandDetail(PathVariable Long id) { return ResponseResult.success(demandService.getDetail(id)); } }系统测试方案单元测试JUnit MockitoExtendWith(MockitoExtension.class) class OrderServiceTest { Mock private DemandRepository demandRepository; InjectMocks private OrderService orderService; Test void createOrder_shouldFailWhenDemandNotExist() { when(demandRepository.findById(any())).thenReturn(Optional.empty()); assertThrows(BusinessException.class, () - orderService.createOrder(1L, 2L)); } }集成测试TestContainersSpringBootTest Testcontainers class TutorInfoRepositoryIT { Container static PostgreSQLContainer? postgres new PostgreSQLContainer(postgres:13); DynamicPropertySource static void configureProperties(DynamicPropertyRegistry registry) { registry.add(spring.datasource.url, postgres::getJdbcUrl); } Test void shouldSaveTutorInfo() { TutorInfo info new TutorInfo(); info.setSubject(数学); tutorInfoRepository.save(info); assertNotNull(info.getTutorId()); } }API测试RestAssuredSpringBootTest(webEnvironment RANDOM_PORT) class DemandApiTest { LocalServerPort private int port; Test void shouldReturn400WhenInvalidInput() { given() .port(port) .contentType(JSON) .body({ \subject\: \\ }) .when() .post(/api/demands) .then() .statusCode(400); } }性能优化措施数据库层面添加索引CREATE INDEX idx_tutor_subject ON tutor_info(subject); CREATE INDEX idx_demand_status ON demand(status);采用Redis缓存热门数据Cacheable(value tutorCache, key #tutorId) public TutorInfo getTutorById(Long tutorId) { return tutorInfoRepository.findById(tutorId).orElse(null); }使用Spring Batch处理批量数据Bean public Job exportJob(JobRepository jobRepository) { return new JobBuilder(exportJob, jobRepository) .start(step1()) .build(); }
