不知道你这个问题是否已经解决, 如果还没有解决的话:

• 你可以参考下这篇文章：Map集合和List集合总结
• 除此之外, 这篇博客: 封装数据到List集合和Map集合中的 封装数据到Map集合 部分也许能够解决你的问题, 你可以仔细阅读以下内容或者直接跳转源博客中阅读:
  
  • 声明map集合

  public class MapAction extends ActionSupport{
  
          private Map<String,User> map;
  
          @Override
              public String execute() throws Exception {
                 System.out.println(map);
                  return NONE;
              }
  }

  • 生成get和set方法

  public class MapAction extends ActionSupport{
  
          private Map<String,User> map;//这里的User类还是和上面的一样
  
  
  
          public Map<String, User> getMap() {
              return map;
          }
  
  
  
          public void setMap(Map<String, User> map) {
              this.map = map;
          }
  
  
  
              @Override
              public String execute() throws Exception {
                 System.out.println(map);
                 System.out.println(map.get("one").getAddress());
                 System.out.println(map.get("two").getUsername());
                  return NONE;
              }
  }

  • 在表单输入项的name属性值里面写表达式

  <%@ page language="java" contentType="text/html; charset=UTF-8"
      pageEncoding="UTF-8"%>
  <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
  <html>
  <head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>Insert title here</title>
  </head>
  <body>
            <form action="${pageContext.request.contextPath}/map.action" method="post">
                username:<input type="text" name="map['one'].username"/>
                <br/>
                password:<input type="text" name="map['one'].password"/>
                <br/>
                address:<input type="text" name="map['one'].address"/>
                <br/><br/>
              username:<input type="text" name="map['two'].username"/>
                <br/>
                password:<input type="text" name="map['two'].password"/>
                <br/>
                address:<input type="text" name="map['two'].address"/>
                <br/>
                <input type="submit" value="提交"/>
         </form>
  </body>
  </html>

  struts.xml

   <action name="map" class="cn.zhoushicanyin.date.MapAction">          
  </action>
