解析：
XStream xs = new XStream();
xs.autodetectAnnotations(true);
xs.alias("Categories", Categories.class);
xs.alias("SuccessResponse", CategorySuccessResponse.class);
CategorySuccessResponse successResponse = (CategorySuccessResponse) xs
.fromXML(response);
错误：

这个错误的原因是什么？
答案 0 :(得分：0)
我也遇到了同样的问题，无论你在哪里定义List数据，都要尝试@XStreamImplicit。
@XStreamAlias("Categories")
public class Categories {
@XStreamImplicit
private List<Category> Category;
}
