关于java:java-结果集工具类

工作中总结的后果集工具类，可灵便增减返回后果字段

工具类:

package com.hy.web.utils;

import java.io.Serializable;
import java.util.HashMap;

public class HyResult extends HashMap<String, Object> implements Serializable {public HyResult() { }

    public HyResult(int code) {this.setCode(code);
    }

    public HyResult(int code, String msg) {this.setCode(code);
        this.setMsg(msg);
    }

    public HyResult(int code, Object data) {this.setCode(code);
        this.setData(data);
    }

    public HyResult(int code, String msg, Object data) {this.setCode(code);
        this.setMsg(msg);
        this.setData(data);
    }

    public HyResult setCode(int code) {this.put("code", code);
        return this;
    }

    public HyResult setMsg(String msg) {this.put("msg", msg);
        return this;
    }

    public HyResult setData(Object data) {this.put("data", data);
        return this;
    }


    public static HyResult ok() {return new HyResult(0);
    }

    public static HyResult fail() {return new HyResult(1, "file");
    }

    public static HyResult fail(String msg) {return new HyResult(1, msg);
    }

    public static HyResult fail(int code, String msg) {return new HyResult(code, msg);
    }

    public static HyResult data(Object data) {return new HyResult(0, data);
    }
}

应用:

/**
     * 胜利
     * @return
     */
    @GetMapping("/test1")
    public HyResult test1() {return HyResult.ok();
    }

    /**
     * 失败
     * @return
     */
    @GetMapping("/test2")
    public HyResult test2() {return HyResult.fail();
    }

    /**
     * 数据
     * @return
     */
    @GetMapping("/test3")
    public HyResult test3() {return HyResult.data("数据");
    }
