注：下面的是EnumObject的枚举类里面的

package com.demo.util;

public enum  EnumObject {
    LOGIN_SUCCESS(1,"登录成功"),
    LOGIN_FAIL(0,"登录超时"),
    LOGIN_NEED(2,"需要登录"),
    LOGIN_ILLEGAL(10,"非法的参数");


    private final int code;
    private final String msg;

    public int getCode() {
        return code;
    }

    public String getMsg() {
        return msg;
    }

    EnumObject(int code, String msg){

        this.code = code;
        this.msg = msg;
    }

}
