统一异常处理类

package com.wdcloud.categoryserver.common.exception;

import com.wdcloud.categoryserver.common.constant.CodeConstants;
import com.wdcloud.categoryserver.common.entity.BaseView;
import org.springframework.http.converter.HttpMessageNotReadableException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.support.MissingServletRequestPartException; import javax.servlet.http.HttpServletRequest; /**
* @describe: 全局异常处理
* @author: zhuchunwang
* @date: 2018/5/29 17:40
* @version: 1.0
*/
@ControllerAdvice(annotations = {RestController.class})
public class GlobalExceptionHandler {
/**
* 默认未知异常
* @param req
* @param e
* @return
* @throws Exception
*/
@ExceptionHandler(value = Exception.class)
@ResponseBody
public BaseView defaultErrorHandler(HttpServletRequest req, Exception e) throws Exception {
e.printStackTrace();
return new BaseView(CodeConstants.SYSTEM_EXCEPTION,CodeConstants.SYSTEM_EXCEPTION_MSG);
} /**
* 参数异常
* @param req
* @param e
* @return
* @throws Exception
*/
@ExceptionHandler(value = {HttpMessageNotReadableException.class, MissingServletRequestPartException.class})
@ResponseBody
public BaseView httpMessageNotReadableExceptionErrorHandler(HttpServletRequest req, Exception e) throws Exception {
e.printStackTrace();
return new BaseView(CodeConstants.PARAMETER_ERROR,CodeConstants.PARAMETER_ERROR_MSG);
}
}

一个参数时这样写

@ExceptionHandler(value = HttpMessageNotReadableException.class)

多个参数时这样写

@ExceptionHandler(value = {HttpMessageNotReadableException.class, MissingServletRequestPartException.class})
