[原创]用iterate输出多维数组

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。
