我有一个从动作类接收集合列表的 JSP。我正在遍历该列表，我希望通过表单请求将该列表的值设置为另一个操作类中的另一个对象。当我<s:property在迭代器中使用标签时使用 displayMovies.jsp，它会显示在集合中的不同对象上。我想将集合中的每个对象保存或传递给不同的操作类。

displayMovies.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1" import="com.sans.model.Movie"  %>
<%@ taglib prefix="s" uri="/struts-tags"%>

您应该status在迭代器标签上使用变量。

<s:form action="movieDetails.action" method="post" id="movieDetailsForm">
<s:iterator value="movieRetrievedArray" var="movieS" status="status">    
    <s:property value="title"/><br />
    <s:property value="releaseDate"/><br />     
    <s:hidden name="movieDetailedInformationList[%{#status.index}].title" value="%{title}" id="hiddenMovie" />
    <br />
    <br />    
</s:iterator>
    <img  src="<s:property value="posterPath" />" onClick="test()">
</s:form>

movieDetailedInformationList是_

private List<Movie> movieDetailedInformationList;

public List<Movie> getMovieDetailedInformationList() { return movieDetailedInformationList; }

您不需要初始化movieDetailedInformationList，因为 Struts2 使用来自发布请求的参数填充它。

该类Movie应该是公共的并且具有默认构造函数，公共设置器title是必要的。
