如何遍历Map< String，List< MyObject>>在JSP中使用struts标记库?

问题描述：

在后端，我有一张地图:

On Backend side I have a Map:

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

MyObject的private String name字段带有公共获取程序和设置程序

MyObject has private String name field with pulic getter and setter

在jsp上，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>

但是我看到错误:

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

我该如何解决?

答

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>
