struts中的迭代器如何和遍历Map中的List集合

Map<string,list>mp = new HashMap<String, List>(); Listpersons = new ArrayList(); Person p1 = new Person(); p1.setId(1); p1.setName("takahashi"); Person p2 = new Person(); p1.setId(2); p1.setName("maeda"); Person p3 = new Person(); p1.setId(3); p1.setName("mayuyu"); Person p4 = new Person(); p1.setId(4); p1.setName("yukirin"); persons.add(p1); persons.add(p2); persons.add(p3); persons.add(p4); mp.put("persons", persons); ActionContext.getContext().put("mp", mp); return SUCCESS;</string,list

Answer 1

<s:iterator value="#mp" id="mp">

  <s:iterator value="#mp.value" status="person">
    <tr>
      <td><s:property value="id"/></td>
      <td><s:property value="name"/></td>

    </tr>
  </s:iterator>
</s:iterator>
