本文介绍了一个Java类的设计，用于封装消息结果，包括事件类型、数据和描述信息。提供了多个构造函数和静态方法来创建不同状态的消息对象，如成功、错误和未登录状态。

1.1.0版本

public class FootResult {
    private String event;
    private Object data;
    private String describe;
    public FootResult(String event,Object data ,String describe){
        super();
        this.event = event;
        this.data = data;
        this.describe = describe;
    }
    public FootResult(String event,String describe){
        this.event = event;
        this.describe = describe;
    }
    public FootResult(){
        super();
    }
    public String getEvent(){
        return event;
    }
    public void setEvent(String event){
        this.event = event;
    }
    public Object getData(){
        return data;
    }
    public void setData(Object data){
        this.data = data;
    }
    public String getDescribe(){
        return describe;
    }
    public void setDescribe(String describe){
        this.describe = describe;
    }
    //请求成功
    public static FootResult SUCCESS(Object data){
        FootResult footResult = new FootResult();
        footResult.setEvent("SUCCESS");
        footResult.setData(data);
        footResult.setDescribe("请求成功");
        return footResult;
    }
    //请求成功
    public static FootResult SUCCESS(String text){
        FootResult footResult = new FootResult();
        footResult.setEvent("SUCCESS");
        footResult.setData(null);
        footResult.setDescribe(text);
        return  footResult;
    }
    //请求失败
    public static FootResult ERROR(Object object){
        FootResult footResult = new FootResult();
        footResult.setEvent("ERROR");
        footResult.setData(object);
        footResult.setDescribe("请求失败");
        return footResult;
    }
    //请求失败，账号密码错误
    public static FootResult ERROR(Object data ,String describe){
        return new FootResult("ERROR",data,describe);
    }
    //请求失败，用户未登录
    public static FootResult NOLOGIN(Object data,String describe){
        return new FootResult("NOLOGIN",data,describe);
    }
}
