1json-lib
<dependency><groupId>net.sf.json-lib</groupId><artifactId>json-lib</artifactId><version>2.4</version><classifier>jdk15</classifier></dependency>
import java.util.HashMap;import java.util.Map;import net.sf.json.JSONObject;public class aaa {public static void main(String[] args) {Map map = new HashMap();map.put("msg", "yes");//map里面装有yesJSONObject jsonObject = JSONObject.fromObject(map);System.out.println("输出的结果是：" + jsonObject);//3、将json对象转化为json字符串String result = jsonObject.toString();System.out.println(result);}}
json-lib是一个比较老的解决方案，近几年都没有升级过，它的适用环境是JDK1.5，使用JDK1.6就有可能会报错。所以配置上加入classifier-jdk15来解决这个问题。JAR下载链接
