</div>
</div>
</div>
</form>
</body>
</html>知识点（1）：从map当中取数据
后台代码
//列表页面
public String listUI(){
//加载权限集合
ActionContext.getContext().getContextMap().put("privilegeMap", PrivilegeStatics.PRIVILEGE_MAP);
roleList = roleService.findAll();
return "listUI";
}在JSP页面取出privilegeMap对象中的数据
<s:iterator value="roleList" status="vs"> <s:iterator value="rolePrivileges"> <s:property value="#privilegeMap[id.code]"/> </s:iterator> </s:iterator>
知识点（2）：
在定义的时候，虽然是String类型，但是在JSP页面判断的时候，似乎没有区分
private String state;
<s:if test="state == 1">有效</s:if><s:else>无效</s:else>
2、addUI.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<div class="p_d_1">
<div class="p_d_1_1">
<div class="content_info">
<div class="c_crumbs"><div><b></b><strong>角色管理</strong> - 新增角色</div></div>
<div class="tableH2">新增角色</div>
<table id="baseInfo" width="100%" align="center" class="list" border="0" cellpadding="0" cellspacing="0" >
<tr>

<td><s:textfield name="role.name" /></td>
</tr>
<tr>
<td class="tdBg" width="200px">角色权限：</td>
<td>
<!--
This is just a detail of the Java Map API.
Instead, it iterates over Entry objects.
The Entry object has two properties, the key and the value.
By default, the select component’s listKey attribute will be set to key.
Also by default, the listValue attribute will be set to value.
If you’re using Maps, you can sometimes accept these defaults.
因此，如果listKey="key"并且listValue="value"，那么这两个值可以省略。
另外，如果省略name属性，会报错！
-->
<s:checkboxlist list="#privilegeMap" name="privilegeIds" listKey="key" listValue="value"></s:checkboxlist>
</td>
</tr>
<tr>
<td class="tdBg" width="200px">状态：</td>
<td><s:radio list="#{'1':'有效','0':'无效'}" name="role.state" value="1"/></td>
</tr>

<input type="button" onclick="javascript:history.go(-1)" class="btnB2" value="返回" />
</div>
</div></div></div>
</form>
</body>
</html>知识点（1）：checklistbox

知识点（2）：radio 有默认值
<s:radio list="#{'1':'有效','0':'无效'}" name="role.state" value="1"/>3、editUI.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<%@include file="/common/header.jsp"%>
<title>角色管理</title>
</head>
<body class="rightBody">

<div class="p_d_1">
<div class="p_d_1_1">
<div class="content_info">
<div class="c_crumbs"><div><b></b><strong>角色管理</strong> - 编辑角色</div></div>
<div class="tableH2">编辑角色</div>

</td>
</tr>
<tr>

</tr>
</table>
<s:hidden name="role.roleId"/>
<div class="tc mt20">
<input type="submit" class="btnB2" value="保存" />
<input type="button" onclick="javascript:history.go(-1)" class="btnB2" value="返回" />
</div>
</div></div></div>
</form>
</body>
</html>知识点（1）：radio 在编辑页面，不需要设置默认值，而是使用它的实际值
<s:radio list="#{'1':'有效','0':'无效'}" name="role.state"/>免责声明：本站发布的内容（图片、视频和文字）以原创、转载和分享为主，文章观点不代表本网站立场，如果涉及侵权请联系站长邮箱：is@yisu.com进行举报，并提供相关证据，一经查实，将立刻删除涉嫌侵权内容。
