XStream反序列化JSON出的郁闷问题,急啊

[haixiang710]

有两个实体bean
ResData .java

public class ResData {
  private String retCode;
  private String retMessage;
  private ArrayList funds;
  get set... ...
}

Fund.java

public class Fund {
  private String name; 
  private String age;
  get set... ...
}

MyTest.java

public class MyTest {
 Fund fund1 = new Fund();
 fund1.setName("zs");
 fund1.setAge("20");
 Fund fund2 = new Fund();
 fund1.setName("ls");
 fund1.setAge("22");

 ArrayList funds = new ArrayList();
 funds.add(fund1);
 funds.add(fund2);

 ResData data = new ResData();
 data.setRetCode("007");
 data.setRetMessage("Over");
 data.setFunds(funds);
  
 //将bean序列化成json
 XStream xStream = new XStream(new JsonHiberarchicalStreamDriver());
 xStream.alias("ResData",ResData.class);
 xStream.alias("funds",Fund.class);
 String json = jsonStream.toXML(data);
 System.out.println(json);

 //将json反序列化成bean(结果报错)
 XStream beanStream = new XStream(new JettisonMappedXmlDriver());
 beanStream.alias("ResData",ResData.class);
 beanStream.alias("funds",Fund.class);
 ResData conData = (ResData)beanStream.fromXML(json);
}

将bean序列化成json时可以,打印出:
{"ResData":{"retCode":"007","retMessage":"over","funds":[{"name":"zs","age":"20"},{"name":"ls","age":"22"}]}}

而json反序列化为bean时那样转不行,请问该怎么反序列化,能让程序知道ResData对应ResData.class
但怎么让程序知道"funds":[{"name":"zs","age":"20"},{"name":"ls","age":"22"}]
是一个Fund类的集合...
急啊....

把bean to json的
XStream xStream = new XStream(new JsonHiberarchicalStreamDriver());
改成
XStream xStream = new XStream(new JettisonMappedXmlDriver());
