此文在“使用struts的标记”一文基础上稍微改动。

iterate-view.jsp:

<logic:iterate id="iterate" name="ibean" property="name" scope="request" offset="0" >
 ★〓〓〓〓〓〓〓〓★<br>
 <%
  String[] temp = (String[]) iterate;
 %>

 <%=temp[0]%> | <%=temp[1]%> | <%=temp[2]%> <p>
</logic:iterate>

IterateAction.java:

package beantest;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class IterateAction extends Action {
 public ActionForward execute(
   ActionMapping mapping,
   ActionForm form,
   HttpServletRequest request,
   HttpServletResponse response) throws Exception {
   IterateBean ibean = (IterateBean) form;
  String[][] temp = {{"a1","a2","a3"},{"b1","b2","b3"}};
  ibean.setName(temp);
  return mapping.findForward("iterate-view");
 }
}

IterateBean.java

package beantest;

import org.apache.struts.action.ActionForm;

public class IterateBean extends ActionForm {
  private String[][] name = null;
 public void setName(String[][] name) {
  this.name = name;
 }
 public String[][] getName() {
  return this.name;
 }
}

输出效果：

http://localhost:8080/mystruts/eye/iterate-test

★〓〓〓〓〓〓〓〓★
a1 | a2 | a3

★〓〓〓〓〓〓〓〓★
b1 | b2 | b3

可见，虽然iterate标记本身比较简单，但结合一些技巧，仍然能够实现一些特殊功能。
