struts2 中在jsp多层迭代要怎么处理

Question

[code="ruby"]
projectList = new ArrayList();
Map map = new HashMap();
map.put("member",memberList.get(0));
map.put("verification", "n");
memberNowList.add(map);
projectList.add(memberNowList);

[/code]
现在在后台有这样的一个list,需要在前台jsp上显示,要怎么做

Answer 1

给你点例子：
Map嵌套Map（自定义对象属性）
[code="java"]public String execute(){
map = new TreeMap>();
Map innerMap = new TreeMap();
UserInfo userInfo = new UserInfo();
userInfo.setUsername("u1");
userInfo.setPassword("p1");
userInfo.setRoleInfo(new RoleInfo("r1"));
userInfo = new UserInfo();
userInfo.setUsername("u11");
userInfo.setPassword("p11");
userInfo.setRoleInfo(new RoleInfo("r11"));
innerMap.put("k1", userInfo);
innerMap.put("k11", userInfo);
map.put("key1", innerMap);
//////////////////////////
innerMap = new TreeMap();
userInfo = new UserInfo();
userInfo.setUsername("u2");
userInfo.setPassword("p2");
userInfo.setRoleInfo(new RoleInfo("r2"));
userInfo = new UserInfo();
userInfo.setUsername("u22");
userInfo.setPassword("p22");
userInfo.setRoleInfo(new RoleInfo("r22"));
innerMap.put("k2", userInfo);
innerMap.put("k22", userInfo);
map.put("key2", innerMap);
}








/s:iterator
/s:iterator [/code]

迭代树
[code="java"]

/s:if

• class="active" /s:if>">

/s:if
/s:iterator

/s:if

• class="active"/s:if>">

/s:if
/s:iterator
