异常处理

全局异常处理

@RestControllerAdvice
@Slf4j
public class GlobalExecptionHandler {

    @ExceptionHandler(BusinessException.class)
    public BaseResponse<?> businessExceptionHandler(BusinessException e) {
        log.error("businessException: " + e.getMessage() + ",描述:" + e.getDescription(), e);
        return ResultUtils.error(e.getCode(), e.getMessage(), e.getDescription());
    }

    @ExceptionHandler(RuntimeException.class)
    public BaseResponse<?> runtimeExceptionHandler(RuntimeException e) {
        log.error("runtimeException", e);
        return ResultUtils.error(CodeEnum.SYSTEM_ERROR, e.getMessage(), "");
    }

}

局部异常处理

@ExceptionHandler(RuntimeException.class)
指定在某个controller类中

统一返回

业务异常

public class BusinessException extends RuntimeException {
    private final int code;
    private final String description;

    public BusinessException(String message, int code, String description) {
        super(message);
        this.code = code;
        this.description = description;
    }

    public BusinessException(CodeEnum errorCode) {
        super(errorCode.getMessage() + "^" + errorCode.getDescription());
        this.code = errorCode.getCode();
        this.description = errorCode.getDescription();
    }

    public BusinessException(CodeEnum errorCode, String description) {
        super(errorCode.getMessage());
        this.code = errorCode.getCode();
        this.description = description;
    }

    public int getCode() {
        return code;
    }

    public String getDescription() {
        return description;
    }
}

返回结果

@Data
public class BaseResponse<T> implements Serializable {

    private int code;
    private T data;
    private String message;
    private String description;

    public BaseResponse(int code, T data, String message, String description) {
        this.code = code;
        this.data = data;
        this.message = message;
        this.description = description;
    }

    public BaseResponse(int code, T data) {
        this(code,data,"","");
    }

    public BaseResponse(CodeEnum codeEnum) {
        this(codeEnum.getCode(),null, codeEnum.getMessage(), codeEnum.getDescription());
    }
}

统一返回工具类

public class ResultUtils {

    public static <T> BaseResponse success(T data) {
        return new BaseResponse(CodeEnum.SUCCESS_STATUS.getCode(), data, CodeEnum.SUCCESS_STATUS.getMessage(), CodeEnum.SUCCESS_STATUS.getDescription());
    }

    public static <T> BaseResponse error(T data) {
        return new BaseResponse(CodeEnum.ERROR_STATUS.getCode(), data, CodeEnum.ERROR_STATUS.getMessage(), CodeEnum.ERROR_STATUS.getDescription());
    }
    
    public static BaseResponse error(int code, String message, String description) {
        return new BaseResponse(code, null, message, description);
    }
    
    public static <T> BaseResponse error(T data,String description) {
        return new BaseResponse(CodeEnum.ERROR_STATUS.getCode(), data, CodeEnum.ERROR_STATUS.getMessage(), description);
    }

    //使用枚举
    public static <T> BaseResponse error(CodeEnum codeEnum) {
        return new BaseResponse(codeEnum);
    }

    public static <T> BaseResponse error(CodeEnum codeEnum, String message, String description) {
        return new BaseResponse(codeEnum.getCode(), null, message, description);
    }
}
