java编写自定义异常类 统一异常处理

/*** 自定义异常类*/public class MyBaseException extends RuntimeException{private static final long serialVersionUID = 1L;public MyBaseException() {}public MyBaseException(String message) {super(message);}}

程序中调用 throw new MyBaseException("异常信息");

@RestControllerAdvicepublic class GlobalExceptionHandler {@ExceptionHandler(MyBaseException .class)public ResponseData exceptionHandler(DateException exception){return handleErrorInfo(exception.getMessage(), "199", exception);}}private ResponseData<String> handleErrorInfo(String message, String code, Exception exception) {exception.printStackTrace();return ResponseData.error(code, message);}

@Getter@AllArgsConstructor(access = AccessLevel.PROTECTED)@NoArgsConstructor(access = AccessLevel.PROTECTED)@JsonInclude(JsonInclude.Include.NON_EMPTY)public class ResponseData<T> implements Serializable {@ApiModelProperty(value="返回码-200成功",name="code",example="200", required=true)private String code;@ApiModelProperty(value="返回描述",name="msg",example="success", required=true)private String msg;@ApiModelProperty(value="返回数据",name="data")private T data;public static ResponseData success(){ResponseData responseData = new ResponseData();responseData.code = "200";responseData.msg = "success";return responseData;}public static ResponseData success(String message){ResponseData responseData = new ResponseData();responseData.code = "200";responseData.msg = message;return responseData;}public ResponseData setData(T t){this.data = t;return this;}public static ResponseData error(String errorMsg){ResponseData responseData = new ResponseData();responseData.code = "999";responseData.msg = errorMsg;return responseData;}public static ResponseData error(String code, String errorMsg){ResponseData responseData = new ResponseData();responseData.code = code;responseData.msg = errorMsg;return responseData;}}
