1、使用：‘js\_sys\_office’表创建树表代码，[JeeSite4自动创建主子表、树表][JeeSite4]

2、将模块添加到菜单栏中

3、编写OfficeController，添加一个跳转页面的请求

@RequiresPermissions("sys:office:view")
    @RequestMapping(value = "index")
    public String index(Office office, Model model) {
    	return "modules/sys/officeIndex";
    }

4、编写前端页面：officeIndex.html

<% layout('/layouts/default.html', {title: '用户管理', libs: ['layout','zTree']}){ %>
    <div class="ui-layout-west">
    	<div class="main-content">
    		<div class="box box-main">
    			<div class="box-header">
    				<div class="box-title">
    					<i class="fa icon-grid"></i> ${text('组织机构')}
    				</div>
    				<div class="box-tools pull-right">
    					<% if(hasPermi('sys:office:edit')){ %>
    						<button type="button" class="btn btn-box-tool addTabPage" data-href="${ctx}/sys/office/list" title="${text('机构管理')}"><i class="fa fa-edit"></i></button>
    					<% } %>
    					<button type="button" class="btn btn-box-tool" id="btnExpand" title="${text('展开')}" style="display:none;"><i class="fa fa-chevron-up"></i></button>
    					<button type="button" class="btn btn-box-tool" id="btnCollapse" title="${text('折叠')}"><i class="fa fa-chevron-down"></i></button>
    					<button type="button" class="btn btn-box-tool" id="btnRefresh" title="${text('刷新')}"><i class="fa fa-refresh"></i></button>
    				</div>
    			</div>
    			<div class="ui-layout-content">
    				<div id="tree" class="ztree"></div>
    			</div>
    		</div>
    	</div>
    </div>
    <div class="ui-layout-center">
    	<iframe id="mainFrame" name="mainFrame" class="ui-layout-content p0"
    		src="${ctx}/sys/empUser/list"></iframe>
    </div>
    <% } %>
    
    <script>
    // 初始化布局
    $('body').layout({
    	west__initClosed: $(window).width() <= 767, // 是否默认关闭
    	west__size: 200
    });
    // 主页框架
    var win = $("#mainFrame")[0].contentWindow;
    
    
    // 树结构初始化加载
    var setting = {view:{selectedMulti:false},data:{key:{title:"title"},simpleData:{enable:true}},
    	callback:{onClick:function(event, treeId, treeNode){
    		tree.expandNode(treeNode);
    		//win.$('button[type=reset]').click();
    		win.$('#officeCode').val(treeNode.id);
    		win.$('#officeName').val(treeNode.name);
    		win.page(1);
    	}}
    }, tree, loadTree = function(){
    	js.ajaxSubmit("${ctx}/sys/office/treeData?___t=" + new Date().getTime(),
    			{ctrlPermi:'${@Global.getConfig("user.adminCtrlPermi", "2")}'/*1拥有的权限 2管理的权限*/}, function(data){
    		tree = $.fn.zTree.init($("#tree"), setting, data);//.expandAll(true);
    		// 展开第一级节点
    		var nodes = tree.getNodesByParam("level", 0);
    		for(var i=0; i<nodes.length; i++) {
    			tree.expandNode(nodes[i], true, false, false);
    		}
    		// 展开第二级节点
    // 		nodes = tree.getNodesByParam("level", 1);
    // 		for(var i=0; i<nodes.length; i++) {
    // 			tree.expandNode(nodes[i], true, false, false);
    // 		}
    	}, null, null, js.text('loading.message'));
    };loadTree();
    
    
    // 工具栏按钮绑定
    $('#btnExpand').click(function(){
    	tree.expandAll(true);
    	$(this).hide();
    	$('#btnCollapse').show();
    });
    $('#btnCollapse').click(function(){
    	tree.expandAll(false);
    	$(this).hide();
    	$('#btnExpand').show();
    });
    $('#btnRefresh').click(function(){
    	loadTree();
    });
    // 调用子页分页函数
    function page(){
    	win.page();
    }
    </script>

5、实现效果
