将Entity转为Map类型

来源：互联网发布：sst nc数据下载编辑：程序博客网时间：2024/05/22 03:33

1、实体类

import java.util.Date;

public class Game {

private int id;

private String gameName;

private Date time;

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getGameName() {

return gameName;

}

public void setGameName(String gameName) {

this.gameName = gameName;

}

public Date getTime() {

return time;

}

public void setTime(Date time) {

this.time = time;

}

public String toString() {

return "Game [id=" + id + ", gameName=" + gameName + ", time=" + time

+ "]";

}

2、处理方法

public class Swap {

public static void main(String[] args) {

Game game = new Game();

game.setId(1);

game.setGameName("梦幻西游");

game.setTime(new Date());

// 将对象转为实体

System.out.println(go(game));

// {id=1, time=Wed Apr 27 11:20:46 CST 2016, class=class Game, gameName=梦幻西游}

}

public static Map<String, Object> go(Object obj){

Class c = null;

Map<String, Object> dataMap = new HashMap<String, Object>();

try {

c = Class.forName(obj.getClass().getName());

//System.out.println(c);//class Game

Method[] methodArr = c.getMethods();

for (Method method : methodArr) {

* 所有方法：

* public java.lang.String Game.toString()

public int Game.getId()

public void Game.setId(int)

public void Game.setGameName(java.lang.String)

public void Game.setTime(java.util.Date)

public java.lang.String Game.getGameName()

public java.util.Date Game.getTime()

//System.out.println(method);

/* method.getName:所有方法名

* toString

getId

setId

setGameName

setTime

getGameName

getTime

wait

equals

hashCode

getClass

notify

notifyAll

//System.out.println(method.getName());

String methodName = method.getName();

if (methodName.startsWith("get")){

/* method.invoke(obj):

* 1

梦幻西游

Wed Apr 27 11:09:15 CST 2016

class Game

Object value = method.invoke(obj);

// 从第三位开始截取

String key = methodName.substring(3);

// 经典

key = key.substring(0,1).toLowerCase() + key.substring(1);

//System.out.println(key);// id gameName, time class

if (null != value){

* java.lang.Integer

java.lang.String

java.util.Date

java.lang.Class

//System.out.println(value.getClass().getName());

if(value.getClass().getClassLoader() != null){ //处理自定义的对象类型

go(value);

}

if("java.util.Date".equals(value.getClass().getName())){

// value = DateUtil.format((Date)value);

//System.out.println(value.getClass().getName());

}

dataMap.put(key, value == null ? "" : value);

} else {

dataMap.put(key, "");

}

} catch (Exception e) {

}

return dataMap;

}
