一、如图：
这里写图片描述
二、Action代码：

package cn.oppo.oa.view.action;import java.util.HashSet;import java.util.List;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Controller;import cn.oppo.oa.base.BaseAction;import cn.oppo.oa.domain.Privilege;import cn.oppo.oa.domain.Role;import com.opensymphony.xwork2.ActionContext;@Controller@Scope("prototype")public class RoleAction extends BaseAction<Role> {    private static final long serialVersionUID = 5242842204530086588L;    private Long[] privilegeIds;    public String list() throws Exception {        List<Role> roleList = roleService.findAll();        ActionContext.getContext().put("roleList", roleList);        return "list";    }    public String addUI() throws Exception {        return "saveUI";    }    public String add() throws Exception {        roleService.add(model);        return "toList";    }    public String delete() throws Exception {        roleService.delete(model.getId());        return "toList";    }    public String editUI() throws Exception {        // 回显数据        Role role = roleService.getById(model.getId());        ActionContext.getContext().getValueStack().push(role);        return "saveUI";    }    public String edit() throws Exception {        // 1.获得实体        Role role = roleService.getById(model.getId());        // 2.设值        role.setName(model.getName());        role.setDescription(model.getDescription());        // 3.更新        roleService.update(role);        return "toList";    }    public String setPrivilegeUI() throws Exception {        // 1.获得实体        Role role = roleService.getById(model.getId());        ActionContext.getContext().getValueStack().push(role);        if (role.getPrivilidges() != null) {            privilegeIds = new Long[role.getPrivilidges().size()];            int i = 0;            for(Privilege privilege : role.getPrivilidges()){                privilegeIds[i++] = privilege.getId();            }        }        List<Privilege> privilegeList = privilegeService.findAll();        ActionContext.getContext().put("privilegeList", privilegeList);        return "setPrivilegeUI";    }    public String setPrivilege() throws Exception {        Role role = roleService.getById(model.getId());        List<Privilege> privileges = privilegeService.getByIds(privilegeIds);        role.setPrivilidges(new HashSet<Privilege>(privileges));        roleService.update(role);        return "toList";    }    public Long[] getPrivilegeIds() {        return privilegeIds;    }    public void setPrivilegeIds(Long[] privilegeIds) {        this.privilegeIds = privilegeIds;    }}

三、页面设计：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><html><head>    <title>配置权限</title>    <%@ include file="/WEB-INF/jsp/public/common.jspf" %>    <script language="javascript" src="${pageContext.request.contextPath}/script/jquery_treeview/jquery.treeview.js"></script>    <link type="text/css" rel="stylesheet" href="${pageContext.request.contextPath}/style/blue/file.css" />    <link type="text/css" rel="stylesheet" href="${pageContext.request.contextPath}/script/jquery_treeview/jquery.treeview.css" />    <script type="text/javascript">        $(function(){            // 给所有的权限复选框添加事件            $("[name=privilegeIds]").click(function(){                // 自己选中或取消时，把所有的下级权限也都同时选中或取消                $(this).siblings("ul").find("input").attr("checked", this.checked);                // 当选中一个权限时，也要同时选中所有的直系上级权限                if(this.checked){                    $(this).parents("li").children("input").attr("checked", true);                }                // 当取消一个权限时，同级没有选中的权限了，就也取消他的上级权限，再向上也这样做。                else{                    if( $(this).parent().siblings("li").children("input:checked").size() == 0 ){                        $(this).parent().parent().siblings("input").attr("checked", false);                        var start = $(this).parent().parent();                        if( start.parent().siblings("li").children("input:checked").size() == 0 ){                            start.parent().parent().siblings("input").attr("checked", false);                        }                    }                }            });        });    </script></head><body><!-- 标题显示 --><div id="Title_bar">    <div id="Title_bar_Head">        <div id="Title_Head"></div>        <div id="Title"><!--页面标题-->            <img border="0" width="13" height="13" src="${pageContext.request.contextPath}/style/images/title_arrow.gif"/> 配置权限        </div>        <div id="Title_End"></div>    </div></div><!--显示表单内容--><div id=MainArea>    <s:form action="roleAction_setPrivilege">        <s:hidden name="id"></s:hidden>        <div class="ItemBlock_Title1"><!-- 信息说明 --><div class="ItemBlock_Title1">            <img border="0" width="4" height="7" src="${pageContext.request.contextPath}/style/blue/images/item_point.gif" /> 正在为【${role.name}】配置权限 </div>         </div>        <!-- 表单内容显示 -->        <div class="ItemBlockBorder">            <div class="ItemBlock">                <table cellpadding="0" cellspacing="0" class="mainForm">                    <!--表头-->                    <thead>                        <tr align="LEFT" valign="MIDDLE" id="TableTitle">                            <td width="300px" style="padding-left: 7px;">                                <!-- 全选 -->                                <input type="checkbox" onClick="$('[name=privilegeIds]').attr('checked', this.checked)"/>                                <label for="cbSelectAll">全选</label>                            </td>                        </tr>                    </thead>                    <!--显示数据列表-->                    <tbody id="TableData">                        <tr class="TableDetail1">                            <!-- 显示权限树 -->                            <td><ul id="root"><%-- 第一级 --%><s:iterator value="#topPrivilegeList">    <li>        <input type="checkbox" name="privilegeIds" value="${id}" id="cb_${id}" <s:property value="%{id in privilegeIds ?
