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

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();
 }}      

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