google json的使用例子

引入maven包：

<dependency>
	<groupId>com.google.code.gson</groupId>
	<artifactId>gson</artifactId>
</dependency>

代码：

public class JsonElementDemo {	
	public static void main(String[] args) {
		JsonObject father = new JsonObject();
		father.addProperty("name", "guanyu");
		father.addProperty("age", "45");
		JsonObject guanxing = new JsonObject();
		guanxing.addProperty("name","guanxing" );
		guanxing.addProperty("age","20" );
		father.add("son", guanxing);
		
		System.out.println(father);
		System.out.println(father.get("son"));
		
	}

}

打印结果：

{"name":"guanyu","age":"45","son":{"name":"guanxing","age":"20"}}
{"name":"guanxing","age":"20"}
