自定义RunTimeException工具类

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;
    }
}
