自定义异常MyInfoException,将异常提示传递给前端

1. 定义一个异常的工具类extends RuntimeException

package com.monkey;

public class MyRuntimeException extends RuntimeException
    private int code;

    MyRuntimeException(int code,String msg)
        super(msg);
        this.code = code;
    


    public int getCode() 
        return code;
    

    public void setCode(int code) 
        this.code = code;
    
    public BasicResponse test()
        BasicResponse<Object> objectBasicResponse = new BasicResponse<>();
        try 
            int i = 6 / 0;
        catch (Exception e)
            objectBasicResponse.setMessge(e.getMessage());


        

        return objectBasicResponse;
    

    public static void main(String[] args) 

        new MyRuntimeException(111,"这个参数有误");
    

2. 封装统一的响应工具类

package com.monkey;

public class BasicResponse<T>
    int code;
    String messge;
    T Data;

    public int getCode() 
        return code;
    

    public void setCode(int code) 
        this.code = code;
    

    public String getMessge() 
        return messge;
    

    public void setMessge(String messge) 
        this.messge = messge;
    

    public T getData() 
        return Data;
    

    public void setData(T data) 
        Data = data;
