GlobalExceptionHandler:

import lombok.extern.slf4j.Slf4j;
import org.springframework.validation.BindingResult;

import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

/**
 * @author javachen
 * @description 全局异常处理类
 */
@Slf4j
@ControllerAdvice
public class GlobalExceptionHandler{

    @ResponseBody
    @ExceptionHandler(CustomException.class)
    public ServerResponse customException(CustomException e){
        log.error("全局异常信息 ex={}", e.getMessage(), e);
        if(null!=e.getCode()){
            return ServerResponse.createByErrorCodeMessage(e.getCode(),e.getMessage());
        }else{
            return ServerResponse.createByErrorMessage(e.getMessage());
        }
    }

    @ResponseBody
    @ExceptionHandler(Exception.class)//指定出现什么异常执行这个方法
    public ServerResponse error(Exception e){
        log.error("自定义异常信息 ex={}", e.getMessage(), e);
        return ServerResponse.createByErrorMessage(e.getMessage());
    }

    @ResponseBody
    @ExceptionHandler(value = MethodArgumentNotValidException.class)
    public ServerResponse MyExceptionHandle(MethodArgumentNotValidException exception){
        exception.printStackTrace();
        BindingResult result = exception.getBindingResult();
        StringBuilder errorMsg = new StringBuilder() ;

        if (result.hasErrors()) {
            List fieldErrors = result.getFieldErrors();
            exception.printStackTrace();
            return ServerResponse.createByErrorMessage(fieldErrors.get(0).getDefaultMessage().toString());
        }
        return ServerResponse.createBySuccess();
    }

}


 

test:
 

   //进行参数校验
   ValidatorUtil.doValidate(sysUserAddBO,Insert.class);
