温馨提示本人主页置顶文章(点我)开头有 CSDN 平台官方提供的学长联系方式的名片技术栈后端框架: Spring Boot 提供快速开发能力整合Spring生态如Spring Security、Spring Data JPA。前端技术: Thymeleaf/Vue.js/React 用于构建动态页面Bootstrap 实现响应式布局。数据库: MySQL/PostgreSQL 存储用户数据、学习资料和测试记录。安全框架: Spring Security 处理用户认证和权限控制。辅助工具: Redis 缓存热点数据Swagger 生成API文档Lombok 简化代码。背景与意义社会需求: 提升公众消防意识减少火灾事故伤亡。技术价值: 通过在线学习降低培训成本实现个性化学习路径。创新点: 结合互动测试、模拟演练等模块增强学习效果。核心代码示例1. 用户认证模块Spring Security配置Configuration EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers(/admin/**).hasRole(ADMIN) .antMatchers(/user/**).authenticated() .anyRequest().permitAll() .and() .formLogin().loginPage(/login); } }2. 知识点管理APIRestController RequestMapping(/api/knowledge) public class KnowledgeController { Autowired private KnowledgeService knowledgeService; GetMapping(/{id}) public ResponseEntityKnowledge getById(PathVariable Long id) { return ResponseEntity.ok(knowledgeService.findById(id)); } }系统测试单元测试: 使用JUnitMockito测试Service层逻辑。Test public void testFindKnowledgeById() { Knowledge mockKnowledge new Knowledge(); when(knowledgeRepository.findById(1L)).thenReturn(Optional.of(mockKnowledge)); Knowledge result knowledgeService.findById(1L); assertNotNull(result); }集成测试: 通过TestRestTemplate测试API接口。UI测试: Selenium自动化测试关键用户流程如登录→学习→测试。数据库设计主要表结构用户表usersCREATE TABLE users ( id BIGINT PRIMARY KEY AUTO_INCREMENT, username VARCHAR(50) UNIQUE, password VARCHAR(100), role ENUM(ADMIN, USER) );知识点表knowledgeCREATE TABLE knowledge ( id BIGINT PRIMARY KEY AUTO_INCREMENT, title VARCHAR(200), content TEXT, category VARCHAR(50) );测试记录表quiz_recordsCREATE TABLE quiz_records ( id BIGINT PRIMARY KEY AUTO_INCREMENT, user_id BIGINT, score INT, FOREIGN KEY (user_id) REFERENCES users(id) );索引优化在频繁查询字段如knowledge.category、quiz_records.user_id上建立索引。
