json - Json struts2 插件中的 includeProperties 不起作用

Question

我正在使用struts2-json-plugin-2.2.3.jar。并尝试序列化类的 filterList 属性，如下所示:

struts.xml代码

<action name="jsonUserFilterListAction"  class="com.my.fitnessb.actions.UserArticlesAction" method="filterList">
        <result  name="success" type="json">
            <param name="includeProperties">filterList</param>
        </result>
 </action>

Action 类

public class UserArticlesAction extends ActionSupport implements SessionAware, ServletRequestAware {

  private List<FilterType> filterList;
  HttpServletRequest request;

  public String filterList() {
    filterList = new ArrayList<FilterType>();
    filterList.add(new FilterType(10, "Latest Articles"));
    filterList.add(new FilterType(1, "Trending Articles"));
    filterList.add(new FilterType(2, "Top Rated Articles"));
    filterList.add(new FilterType(3, "Most Viewd Atricles"));
    filterList.add(new FilterType(4, "All Atricles"));
    return SUCCESS;
  }
  //setter & getter of filterList
}

但我无法获取 FilterType 类的此属性。

假设 FilterType 中的字段名为 id 和 desc

尝试

<param name="includeProperties">
filterList\[\d+\]\.id,
filterList\[\d+\]\.desc
</param>
