1】把tree定义在一个空<ul>元素

2】使用Javascript加载数据

3】resourceController中的tree方法

@RequestMapping("/tree")@ResponseBodypublic List
    
      tree(HttpSession session) {    //获取当前账户的用户信息(包括ID/登录名/用户可以访问的资源地址列表)	SessionInfo sessionInfo = (SessionInfo) session.getAttribute(ConfigUtil.getSessionInfoName());	return resourceService.tree(sessionInfo);}
    

4】resourceService的tree方法

public List
    
      tree(SessionInfo sessionInfo) {		List
     
       l = null;		List
      
        lt = new ArrayList
       
        ();		Map
        
          params = new HashMap
         
          (); params.put("resourceTypeId", "0");// 菜单类型的资源 if (sessionInfo != null) { params.put("userId", sessionInfo.getId());// 自查自己有权限的资源 l = resourceDao.find("select distinct t from Tresource t join fetch t.tresourcetype type join fetch t.troles role join role.tusers user where type.id = :resourceTypeId and user.id = :userId order by t.seq", params); } else { l = resourceDao.find("select distinct t from Tresource t join fetch t.tresourcetype type where type.id = :resourceTypeId order by t.seq", params); } if (l != null && l.size() > 0) { for (Tresource r : l) { Tree tree = new Tree(); BeanUtils.copyProperties(r, tree); if (r.getTresource() != null) { tree.setPid(r.getTresource().getId()); } tree.setText(r.getName()); tree.setIconCls(r.getIcon()); Map
          
            attr = new HashMap
           
            (); attr.put("url", r.getUrl()); tree.setAttributes(attr); lt.add(tree); } } log.info("debug级别的日志输出----"+JSON.toJSONString(lt)); return lt; }
           
          
         
        
       
      
     
    

5】返回的JSON数据如下：

[    {        "attributes": {},        "checked": false,        "iconCls": "plugin",        "id": "xtgl",        "state": "open",        "text": "系统管理"    },    {        "attributes": {            "url": "/chartController/userCreateDatetimeChart"        },        "checked": false,        "iconCls": "chart_curve",        "id": "userCreateDatetimeChart",        "pid": "chart",        "state": "open",        "text": "用户图表"    },    {        "attributes": {            "url": "/resourceController/manager"        },        "checked": false,        "iconCls": "database_gear",        "id": "zygl",        "pid": "xtgl",        "state": "open",        "text": "资源管理"    },    {        "attributes": {            "url": "/roleController/manager"        },        "checked": false,        "iconCls": "tux",        "id": "jsgl",        "pid": "xtgl",        "state": "open",        "text": "角色管理"    },    {        "attributes": {            "url": "/userController/manager"        },        "checked": false,        "iconCls": "status_online",        "id": "yhgl",        "pid": "xtgl",        "state": "open",        "text": "用户管理"    },    {        "attributes": {            "url": "/bugController/manager"        },        "checked": false,        "iconCls": "bug",        "id": "buggl",        "pid": "xtgl",        "state": "open",        "text": "BUG管理"    },    {        "attributes": {            "url": "/druidController/druid"        },        "checked": false,        "iconCls": "server_database",        "id": "sjygl",        "pid": "xtgl",        "state": "open",        "text": "数据源管理"    }]

6】返回的JSON，通过onLoadSuccess方法接收，数据就装填进Tree控件里了
