JSONObject 的简单使用

需要基本的jar包

1.commons-lang.jar

      2.commons-beanutils.jar

      3.commons-collections.jar

      4.commons-logging.jar 

      5.ezmorph.jar

      6.json-lib-2.2.2-jdk15.jar

package test.json;

import net.sf.json.JSONObject;

public class JsonTest {

 public static void main(String[] args) {  JSONObject jsonObject = new JSONObject();    jsonObject.put("name" ,  "kevin" );     jsonObject.put("Max.score" ,  new  Integer( 100 ));     jsonObject.put("nickname" ,  "picglet" ); // 这里是要被下面一行代码的效果覆盖的   jsonObject.put("nickname" ,  "picglet123" );   jsonObject.put("children" , buildSubJson() );     System.out.println(jsonObject.toString()); }  public static String buildSubJson(){  JSONObject jsonObject = new JSONObject();  jsonObject.put("sub1" ,  "kevin" );     jsonObject.put("sub2" ,  new  Integer( 100 ));       return jsonObject.toString(); }

}

结果 ：

{"nickname":"picglet123","Max.score":100,"Min.score":50,"name":"kevin","children":{"sub2":100,"sub1":"kevin"}}
