启动类
@MapperScan("jkw.mapper") @SpringBootApplication public class Main { @Bean public MybatisPlusInterceptor mybatisPlusInterceptor() { MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor(); //分页插件 interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL)); return interceptor; } public static void main(String[] args) { SpringApplication.run(Main.class, args); } }
返回结果封装
CodeEnum
@Getter @AllArgsConstructor public enum CodeEnum { SUCCESS(200, "OK"), SYSTEM_ERROR(500, "系统异常"), FILE_FASTDFS_UPLOAD_ERROR(601,"fastdfs文件上传异常"), FILE_FASTDFS_DELETE_ERROR(602,"fastdfs文件删除异常"), ; private final Integer code; private final String message; }
BaseResult
@Data @AllArgsConstructor public class BaseResult<T> implements Serializable { //状态码(成功：200，失败：其他) private Integer code; //提示信息 private String message; //返回数据 private T data; //构建成功结果 public static <T> BaseResult<T> ok(){ return new BaseResult(CodeEnum.SUCCESS.getCode(),CodeEnum.SUCCESS.getMessage(),null); } //构建带有数据的成功结果 public static <T> BaseResult<T> ok(T data){ return new BaseResult(CodeEnum.SUCCESS.getCode(),CodeEnum.SUCCESS.getMessage(),data); } }
全局异常处理
自定义异常类
@Data public class MyException extends RuntimeException implements Serializable { private Integer code; private String message; public MyException() { } public MyException(Integer code, String message) { this.code = code; this.message = message; } }
全局异常处理器
@RestControllerAdvice public class GlobalExceptionHandler { //处理自定义异常 @ExceptionHandler(MyException.class) public BaseResult defaultExceptionHandler(HttpServletRequest req, HttpServletResponse resp, MyException e) { BaseResult baseResult = new BaseResult(e.getCode(), e.getMessage(), null); return baseResult; } // 处理权限不足异常，捕获到异常后再次抛出，交给AccessDeniedHandler处理 @ExceptionHandler(AccessDeniedException.class) public void defaultExceptionHandler(AccessDeniedException e) throws AccessDeniedException { throw e; } //上面处理不了的交给系统异常处理 @ExceptionHandler(java.lang.Exception.class) public BaseResult defaultExceptionHandler(HttpServletRequest req, HttpServletResponse resp, Exception e) { e.printStackTrace(); BaseResult baseResult = new BaseResult(CodeEnum.SYSTEM_ERROR.getCode(), CodeEnum.SYSTEM_ERROR.getMessage(), null); return baseResult; } }
