如何使用 struts 标签库遍历 jsp 中的 Map<String, List<MyObject>>?

How to iterate over Map<String, List<MyObject>> in the jsp using struts tag library?

在后端我有一个地图:

SortedMap<String, List<MyObject>> myMap = new TreeMap<>()

MyObjectprivate String name 字段,公共 getter 和 setter

在 jsp 我有:

<nested:iterate property="myMap" id="map">
     <bean:write name="map" property="key"/>
      <nested:iterate property="listElement" id="value">
          <bean:write name="value" property="name"/>
      </nested:iterate>
</nested:iterate>

但我看到错误:

Caused by: javax.servlet.jsp.JspException: No getter method for property: "otherBean.MyMap(API).listElement" of bean: "MyBeanForm"

我该如何解决?

有效

<nested:iterate property="myMap" id="entry">
     <bean:write name="entry" property="key"/>
      <nested:iterate property="value" name="entry" id="obj">
          <bean:write name="obj" property="name"/>
      </nested:iterate>
</nested:iterate>
