spring boot全局捕获异常

异常处理

public interface baseErrorInfoInterface {

    
    String getResultCode();

    
    String getResultMsg();
}

枚举类

public enum ExceptionEnum implements baseErrorInfoInterface{

    // 数据操作错误定义
    BODY_NOT_MATCH("4000","请求的数据格式不符!");
    
    private final String resultCode;

    
    private final String resultMsg;

    ExceptionEnum(String resultCode, String resultMsg) {
        this.resultCode = resultCode;
        this.resultMsg = resultMsg;
    }

    @Override
    public String getResultCode() {
        return resultCode;
    }

    @Override
    public String getResultMsg() {
        return resultMsg;
    }
}

捕获全局异常

@ControllerAdvice
public class GlobalExceptionHandler {

    private static final Logger logger = LoggerFactory.getLogger(GlobalExceptionHandler.class);

    
    @ExceptionHandler(value = BizException.class)
    @ResponseBody
    public Result bizExceptionHandler(HttpServletRequest req, BizException e){
        logger.error("发生业务异常！原因是：{}",e.getErrorMsg());
        return Result.fail(e.getErrorMsg());
    }

    
    @ExceptionHandler(value =NullPointerException.class)
    @ResponseBody
    public Result exceptionHandler(HttpServletRequest req, NullPointerException e){
        logger.error("发生空指针异常！原因是:",e);
        return Result.fail(ExceptionEnum.BODY_NOT_MATCH);
    }

    
//    @ExceptionHandler(value =Exception.class)
//    @ResponseBody
//    public ResultResponse exceptionHandler(HttpServletRequest req, Exception e){
//        logger.error("未知异常！原因是:",e);
//        return ResultResponse.error(ExceptionEnum.INTERNAL_SERVER_ERROR);
//    }
}
