public class MuyaLCResultsBean<T> {

public String className;
}
String strBody = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
MuyaLCResultsBean<MuyaLCFamilyBindRelationBean> bean = ReadJson(strBody, MuyaLCResultsBean.class);
MuyaLCFamilyBindRelationBean first = bean.results.get(0); // （2）此处报错，错误请参见下面
String strResult = first.ToJson();
System.out.println(strResult);
运行至（2）处，出现Exception：
Exception in thread "main" java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.aika.kidtracker.cloud.MuyaLCFamilyBindRelationBean
at com.aika.kidtracker.cloud.WebUtilMain.TestCQL(WebUtilMain.java:544)
at com.aika.kidtracker.cloud.WebUtilMain.main(WebUtilMain.java:66)
我的个人推断是，ReadJson()传入的第二个class只是MuyaLCResultsBean，因此，进行到（1）处时，
objectMapper.readValue(_strJson, _class);
是根本不知道真正要解析的类的具体格式，就默认解析成LinkHashMap了。
请高手帮助，如何修改代码？
