Service中定义的异常

package com.cy.pj.common.excpetion;

public class ServiceException extends RuntimeException{

	private static final long serialVersionUID = 1L;
	public ServiceException() {
		super();
		// TODO Auto-generated constructor stub
	}
	public ServiceException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
		super(message, cause, enableSuppression, writableStackTrace);
		// TODO Auto-generated constructor stub
	}
	public ServiceException(String message, Throwable cause) {
		super(message, cause);
		// TODO Auto-generated constructor stub
	}
	public ServiceException(String message) {
		super(message);
		// TODO Auto-generated constructor stub
	}
	public ServiceException(Throwable cause) {
		super(cause);
		// TODO Auto-generated constructor stub
	}
}

全局异常类

package com.cy.pj.common.web;

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
import com.cy.pj.common.vo.JsonResult;
/**全局异常处理类*/
@ControllerAdvice
public class GlobalExceptionHandler {
	//JDK中的自带的日志API
	@ExceptionHandler(RuntimeException.class)
    @ResponseBody
	public JsonResult doHandleRuntimeException(
			RuntimeException e){
    	e.printStackTrace();//也可以写日志
		return new JsonResult(e);//封装异常信息
	}
}
