我正在使用下面的代码，
String companyString= gson.toJson( "Here - List of objects converted to string" );
List<SExecutive> sExecutiveList = gson.fromJson( companyString,
new TypeToken<List>()
{
}.getType() );
上面的代码在运行时没有错误，它生成了sExecutiveList。但是当我在列表中使用对象时，它会抛出错误，
java.lang.ClassCastException: java.lang.Object cannot be cast to com.deloitte.iq.data.beans.solr.SExecutive
