如何用eclipse实现gson解析json

Answer 1

以一个简单的例子来说明下吧。
这是一个java Bean

package baz.javabean;

import java.sql.Timestamp;

public class Product {

private String name;
private int id;
private Timestamp date;

public Product() {
// TODO Auto-generated constructor stub
}

public Product(String name, int id, Timestamp date) {
super();
this.name = name;
this.id = id;
this.date = date;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public Timestamp getDate() {
return date;
}

public void setDate(Timestamp date) {
this.date = date;
}

}

下边是一个Test类

package baz.test;

import baz.javabean.Product;

import com.google.gson.Gson;

public class Test1 {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

Gson gson = new Gson();//new一个Gson对象
//json字符串
String json = "{\"name\":\"guolicheng\",\"id\":123456,\"date\":\"2013-4-13 12:36:54\"}";
//new 一个Product对象
Product product = new Product();
//将一个json字符串转换为java对象
product = gson.fromJson(json, Product.class);
//输出
System.out.println("Name:" + product.getName());
System.out.println("Id:" + product.getId());
System.out.println("Date:" + product.getDate());
}

}

输出结果为：

Name:guolicheng
Id:123456
Date:2013-04-13 12:36:54.0
