2.2 全局异常处理机制
2.2.1 异常处理设计目标
统一异常响应格式JSON格式区分业务异常与系统异常记录异常日志集成SLF4J返回友好提示信息如{code: 500, msg: 系统错误, data: null} 2.2.2 核心代码实现
1. 自定义业务异常类
// 自定义业务异常用于抛出可预期的错误
public class BusinessException extends RuntimeException {private Integer code;public BusinessException(Integer code, String message) {super(message);this.code code;}public Integer getCode() {return code;}
}2. 全局异常拦截器
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;ControllerAdvice
public class GlobalExceptionHandler {private static final Logger logger LoggerFactory.getLogger(GlobalExceptionHandler.class);// 业务异常处理 ExceptionHandler(BusinessException.class)public ResponseEntity? handleBusinessException(BusinessException e) {logger.error(Business Error: {}, e.getMessage(), e);return ResponseEntity.status(HttpStatus.OK).body(ResultUtil.error(e.getCode(), e.getMessage()));}// 系统异常处理 ExceptionHandler(Exception.class)public ResponseEntity? handleSystemException(Exception e) {logger.error(System Error: {}, e.getMessage(), e);return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(ResultUtil.error(500, 系统繁忙请稍后再试));}
}3. 统一响应结果工具类
public class ResultUtil {// 成功响应 public static T MapString, Object success(T data) {return buildResult(200, success, data);}// 错误响应 public static MapString, Object error(Integer code, String msg) {return buildResult(code, msg, null);}private static T MapString, Object buildResult(Integer code, String msg, T data) {MapString, Object result new HashMap();result.put(code, code);result.put(msg, msg);result.put(data, data);return result;}
}2.2.3 异常处理示例 场景用户请求不存在的课程ID时触发异常
Controller代码片段
GetMapping(/courses/{id})
public ResponseEntity? getCourse(PathVariable Long id) {Course course courseService.getById(id);if (course null) {throw new BusinessException(404, 课程不存在);}return ResponseEntity.ok(ResultUtil.success(course));
}返回结果
{code: 404,msg: 课程不存在,data: null
}2.2.4 扩展性设计
多异常类型支持通过ExceptionHandler可添加更多异常类型如MethodArgumentNotValidException国际化支持结合MessageSource实现多语言错误提示熔断降级集成Hystrix/Sentinel实现异常熔断 2.3 MyBatis-Plus分页插件集成Interceptor实现代码 二、后端核心开发Spring Boot MyBatis-Plus
2.3 MyBatis-Plus分页插件集成
2.3.1 分页插件核心价值
简化分页逻辑无需手写LIMIT语句兼容数据库方言自动适配MySQL/Oracle/SQL Server等支持复杂查询嵌套查询、联合查询均可分页 2.3.2 插件配置实现
1. 分页插件注册MyBatis-Plus配置类
Configuration
public class MyBatisPlusConfig {Bean public MybatisPlusInterceptor mybatisPlusInterceptor() {MybatisPlusInterceptor interceptor new MybatisPlusInterceptor();// 添加分页拦截器 interceptor.addInnerInterceptor(new PaginationInnerInterceptor());return interceptor;}
}2. 自定义分页参数封装
public class PageParam {private Integer pageNum 1; // 当前页码 private Integer pageSize 10; // 每页记录数 private String orderByField; // 排序字段 private Boolean ascending true; // 排序方式 // Getter/Setter 省略
}2.3.3 分页查询实现示例
场景分页查询课程列表按创建时间降序排列
Service层代码
public PageCourse listCourses(PageParam pageParam) {// 封装分页参数 PageCourse page new Page(pageParam.getPageNum(), pageParam.getPageSize());// 设置排序 page.addOrder(new OrderItem(pageParam.getOrderByField(), pageParam.isAscending()));// 调用Mapper执行分页查询 return courseMapper.selectPage(page, null);
}Controller层代码
PostMapping(/courses/page)
public ResponseEntity? getCourses(RequestBody PageParam pageParam) {PageCourse page courseService.listCourses(pageParam);return ResponseEntity.ok(ResultUtil.success(page));
}2.3.4 分页结果示例
{code: 200,msg: success,data: {records: [/* 课程数据 */],total: 100, // 总记录数 size: 10, // 每页数量 current: 1, // 当前页码 pages: 10 // 总页数 }
}2.3.5 高级用法 复杂条件分页 LambdaQueryWrapperCourse wrapper new LambdaQueryWrapper();
wrapper.eq(Course::getTeacherId, teacherId);
return courseMapper.selectPage(page, wrapper);关联查询分页 // 通过TableName注解关联查询
PageCourse page new Page(1, 10);
page.setRecords(courseMapper.selectJoinPage(page, new String[]{teacher}, // 需要关联的表别名 new Object[]{teacherId} // 关联条件参数
));2.3.6 性能优化建议
避免分页过大限制pageSize最大值如不超过100延迟加载关联对象通过TableField(exist false)延迟加载学生列表索引优化在create_time等排序字段添加索引 2.4 JWT鉴权体系构建Token生成与校验完整流程 二、后端核心开发Spring Boot MyBatis-Plus
2.4 JWT鉴权体系构建
2.4.1 JWT核心原理
Token结构Header算法声明 Payload用户信息 Signature签名安全性保障 HS256算法加密密钥需严格保密Token有效期控制避免长期暴露风险签名校验防止篡改 2.4.2 核心代码实现
1. Token生成工具类
Component
public class TokenService {private static final String SECRET your-secret-key-123456; // 生产环境需加密存储 private static final Long EXPIRE_TIME 1800L; // 30分钟单位秒public String generateToken(Long userId) {return Jwts.builder().setSubject(edu-system) // 系统标识 .claim(userId, userId) // 用户ID .setIssuedAt(new Date()) // 签发时间 .setExpiration(new Date(System.currentTimeMillis() EXPIRE_TIME * 1000)).signWith(SignatureAlgorithm.HS256, SECRET).compact();}public Claims parseToken(String token) {return Jwts.parser().setSigningKey(SECRET).parseClaimsJws(token).getBody();}
}2. JWT拦截器实现
Component
public class JwtInterceptor implements HandlerInterceptor {Autowired private TokenService tokenService;Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {// 排除登录接口 if (request.getRequestURI().equals(/api/login)) {return true;}String token request.getHeader(Authorization);if (StringUtils.isEmpty(token)) {throw new BusinessException(401, 未登录);}try {Claims claims tokenService.parseToken(token);// 将用户ID存入ThreadLocal供Service层使用UserContext.setUserId(Long.parseLong(claims.get(userId).toString()));} catch (Exception e) {throw new BusinessException(401, Token无效或已过期);}return true;}
}3. 拦截器注册配置
Configuration
public class WebMvcConfig implements WebMvcConfigurer {Autowired private JwtInterceptor jwtInterceptor;Override public void addInterceptors(InterceptorRegistry registry) {registry.addInterceptor(jwtInterceptor).addPathPatterns(/**) // 全局拦截 .excludePathPatterns(/api/login); // 排除登录接口 }
}2.4.3 登录接口实现
RestController
public class AuthController {PostMapping(/api/login)public ResponseEntity? login(RequestBody User user) {// 简化版校验逻辑实际需查询数据库if (!admin.equals(user.getUsername()) || !123456.equals(user.getPassword())) {throw new BusinessException(401, 用户名或密码错误);}String token tokenService.generateToken(1L); // 假设用户ID为1 return ResponseEntity.ok(ResultUtil.success(token));}
}2.4.4 Postman测试案例 登录请求 URL: POST http://localhost:8080/api/loginBody:{username: admin,password: 123456
}响应{code: 200,msg: success,data: eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJlZHVfc3lzdGVtIiwic3ViIjoiMSIsImlhdCI6MTcxNjI3ODQwNSwiZXhwIjoxNzE2Mjc4NzA1fQ.SigNsignature
}受保护接口访问 URL: GET http://localhost:8080/api/coursesHeaders:Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJlZHVfc3lzdGVtIiwic3ViIjoiMSIsImlhdCI6MTcxNjI3ODQwNSwiZXhwIjoxNzE2Mjc4NzA1fQ.SigNsignature 响应课程列表数据需登录后可见 2.4.5 安全性增强建议 密钥管理 使用Vault或Spring Cloud Config动态管理密钥定期轮换密钥需处理旧Token失效问题 Token刷新机制 // 增加刷新接口返回新Token
PostMapping(/api/refresh-token)
public ResponseEntity? refreshToken(RequestHeader(Authorization) String oldToken) {// 校验旧Token有效性后生成新Token return ResponseEntity.ok(ResultUtil.success(tokenService.generateToken(1L)));
}黑名单机制 使用Redis存储已注销Token拦截器中增加黑名单校验 2.5 文件上传优化方案MultipartFile处理代码 二、后端核心开发Spring Boot MyBatis-Plus
2.5 文件上传优化方案
2.5.1 核心需求与痛点
大文件上传单文件超过100MB时易超时并发处理高并发场景下IO阻塞安全性防止恶意文件上传存储优化分布式存储与本地缓存结合 2.5.2 核心代码实现
1. 分片上传核心逻辑
RestController
public class FileUploadController {PostMapping(/upload/chunk)public ResponseEntity? uploadChunk(RequestParam(file) MultipartFile file,RequestParam(chunkIndex) Integer chunkIndex,RequestParam(totalChunks) Integer totalChunks) {// 校验分片完整性 if (chunkIndex 0 || chunkIndex totalChunks) {throw new BusinessException(400, 分片索引无效);}// 保存分片到临时目录 String tempDir upload_temp/ file.getOriginalFilename();File tempFile new File(tempDir, chunkIndex .part);try {Files.createDirectories(Paths.get(tempDir));file.transferTo(tempFile.toPath());} catch (IOException e) {throw new RuntimeException(分片保存失败, e);}return ResponseEntity.ok(ResultUtil.success(分片上传成功));}PostMapping(/upload/merge)public ResponseEntity? mergeChunks(RequestParam(fileName) String fileName,RequestParam(totalChunks) Integer totalChunks) {// 合并分片 String tempDir upload_temp/ fileName;File[] chunkFiles new File(tempDir).listFiles((dir, name) - name.endsWith(.part));if (chunkFiles.length ! totalChunks) {throw new BusinessException(400, 分片缺失);}// 按索引排序 Arrays.sort(chunkFiles, Comparator.comparingInt(f - Integer.parseInt(f.getName().replace(.part, ))));// 合并到目标文件 String targetPath upload/ fileName;try (RandomAccessFile raf new RandomAccessFile(targetPath, rw)) {for (File chunk : chunkFiles) {try (FileInputStream fis new FileInputStream(chunk)) {byte[] buffer new byte[1024];int len;while ((len fis.read(buffer)) ! -1) {raf.write(buffer, 0, len);}}}} catch (IOException e) {throw new RuntimeException(文件合并失败, e);}// 清理临时文件 FileUtils.deleteDirectory(new File(tempDir));return ResponseEntity.ok(ResultUtil.success(文件合并成功));}
}2. 文件类型与大小校验
Component
public class FileValidator {private static final SetString ALLOWED_TYPES new HashSet(Arrays.asList(image/jpeg, image/png, application/pdf));public void validate(MultipartFile file) {// 校验文件类型 String mimeType Files.probeContentType(Paths.get(file.getOriginalFilename()));if (!ALLOWED_TYPES.contains(mimeType)) {throw new BusinessException(400, 文件类型不支持);}// 校验文件大小示例限制50MBif (file.getSize() 50 * 1024 * 1024) {throw new BusinessException(400, 文件大小超过限制);}}
}3. 存储路径生成策略
public class FilePathGenerator {public static String generatePath(String originalFilename) {// 按日期分区存储 String dateDir DateTimeFormatter.ofPattern(yyyy/MM/dd).format(LocalDateTime.now());// 使用MD5哈希文件名防止冲突 String hash DigestUtils.md5Hex(originalFilename.getBytes());return String.format(%s/%s_%s, dateDir, hash, originalFilename);}
}2.5.3 配置优化
# application.yml
spring:servlet:multipart:max-file-size: 200MB # 单文件最大限制 max-request-size: 200MB # 总请求体限制 file-size-threshold: 2MB # 超过2MB使用临时文件存储 location: /tmp/upload # 临时目录 2.5.4 性能测试与优化 NIO优化 // 使用NIO提升大文件写入性能
StandardOpenOption[] options {StandardOpenOption.CREATE, StandardOpenOption.WRITE};
Files.write(Paths.get(targetPath), file.getBytes(), options);异步处理 Async
public CompletableFutureString asyncUpload(MultipartFile file) {// 异步保存文件到OSS return CompletableFuture.completedFuture(上传成功);
}2.5.5 测试案例 分片上传测试 使用Postman发送3个分片每个10MB最终合并生成30MB文件控制台输出2023-10-01 15:20:00.000 INFO 12345 --- [ main] c.b.a.FileUploadController : 分片0上传成功
