注意几个注解：@ControllerAdvice     @ExceptionHandler    @ResponseBody

package com.sayhello.sayhello.Handle;


import com.sayhello.sayhello.Exception.GirlException;
import com.sayhello.sayhello.Utils.ResultUtils;
import com.sayhello.sayhello.domain.Result;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

@ControllerAdvice
public class GirlHandle {

    @ExceptionHandler(value = GirlException.class)
    @ResponseBody
    public Result handleException(GirlException e){
        //System.out.println(e.getMessage());
        return ResultUtils.error(e.getCode(),e.getMessage());
    }
}
