json-lib-xxx.jar

ezmorph-xxx.jar  //=============>依赖包

JsonConfig config = new JsonConfig();//有选择性的过滤掉一些属性值

 JSONUtils.getMorpherRegistry().registerMorpher( new DateMorpher(new String[] { "yyyy-MM-dd" }));//注册一个json转为java.util.date的日期格式

 JSONObject o = JSONObject.fromObject(jsonString, config);

  if (clazz == null) {

   return (T) JSONObject.toBean(o);

  } else {

   return (T) JSONObject.toBean(o, clazz);

  }

=====================================================================================================

public static void main(String[] args) {

Map map=new HashMap();

map.put("我","妹");

map.put("擦","哇");

map.put("你","呀");

JSONObject json = JSONObject.fromObject(map);

System.out.println(json);

}

輸出的結果 {"我":"妹","擦":"哇","你":"呀"}

然后测试toBean方法的类

import net.sf.json.JSONObject;

public class ToBeanTest {

public static void main(String[] args) {

String json = "{id:'1001',name:'张三',age:'22'}";

Student stu = new Student();

JSONObject obj = JSONObject.fromObject(json);

stu = (Student)JSONObject.toBean(obj, Student.class);

System.out.println(stu);

}

}

输出结果为1001, 张三, 22
