先贴代码

public static void main(String[] args) {

		String json="{"+

			            "'PriceProductType': '1',"+

			            "'PriceRouteType': 'OW',"+

			                "'RefundedComment': '航班起飞前2小时（含），免费退票；航班起飞前2小时内及航班起飞后，收取10%的退票手续费（退票手续费不得低于50元）。',"+

			        "}";

		json = json.replace("null", "1111");

		System.out.println(json);

你想他自动转为bean啊，不如你自己遍历一下JSONObject，将get得到的数据赋值给bean不就行了。

要把Json字符串直接转换为java对象，并且转化了的java对象里要有值

两个库用得比较多：fastjson 和 gson。

举个例吧：



import net.sf.json.JSONObject;



public class JsonTest {



	public static void main(String[] args) {

		String str = "{\"lendperson\":\"李四\",\"lendcompany\":\"有限公司\",\"checkperson\":\"李四\",\"lenddate\":\"2010-07-19T00:00:00\",\"lendcounts\":4,\"" +

				"passports\":[{\"passportid\":\"d\",\"name\":\"李豫川\",\"passporttype\":\"K\"},{\"passportid\":\"K9051\",\"name\":\"李平\",\"passporttype\":\"K\"}," +

				"{\"passportid\":\"K90517\",\"name\":\"袁寒梅\",\"passporttype\":\"K\"},{\"passportid\":\"K905199\",\"name\":\"贺明\",\"passporttype\":\"K\"}]}";

		

		JSONObject j = JSONObject.fromObject(str);

		System.out.println(j.get("lendperson"));

	}

}

要使程序可以运行必须引入JSON-lib包，JSON-lib包同时依赖于以下的JAR包：
commons-lang.jar
commons-beanutils.jar
commons-collections.jar
commons-logging.jar
ezmorph.jar
json-lib-2.2.2-jdk15.jar
