Javascript 樹形菜單

    

 

 

   用Hibernate+Struts+Spring做了一個簡單的樹形菜單..通過dtree.js組件顯示樹形菜單。

   具體Sql代碼以及java後臺的實現代碼都貼出來.以供參考..

   數據庫表的代碼:

 

  

--權限涉及的如下五個表;
drop table roles;
drop table user_roles;
drop table menus;
drop table rols_menus;
drop table users;

     

      

  

--用戶表;
create table users(
     --主鍵,
     userid number primary key not null,

   BaseDAO中的查詢方法.

/**
     * 分頁查找;
     * @param hql
     * @param page
     * @param size
     * @param objects
     * @return
     */
    public List pageQuery(final String hql,final Integer page,final Integer size,final Object...objects){

        return super.getHibernateTemplate().executeFind(new HibernateCallback(){
            //一個匿名內部類;
            public Object doInHibernate(Session session)
                    throws HibernateException, SQLException {
                // TODO Auto-generated method stub
                Query query=session.createQuery(hql);
                if(objects!=null){
                    for(int i=0;i<objects.length;i++){
                        query.setParameter(i, objects[i]);
                    }
                }

                if(page!=null&& size!=null){
                    query.setFirstResult((page-1)*size).setMaxResults(size);
                }

                return query.list();
            }

        });
    }

   

 

 

service中的方法,根據用戶名獲取所有菜單;

   

/**
     * 根據用戶名得到菜單     */
    public Set selectByName(String name) {
        // TODO Auto-generated method stub
          String hql="From Menus as M join fetch M.roleses R join fetch R.userses U where U.username=?";
        List list=iuser.pageQuery(hql, null, null,name);
        //把list轉成set集合;
        Set set=new HashSet(list);
        return set;
    }

    

 

  

 

 

   在Action中. 調用service中的方法。根據用戶查找得到菜單;保存到session中。

Set menus=iser.selectByName(name);
   System.out.println("菜單項:"+menus);
   //把菜單項設置到session中;
   request.getSession().setAttribute("MeunsList",menus);

  

 

在JSP也頁面使用dTree的方式是:

<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%@taglib  prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<script type="text/javascript" src="dtree/dtree.js"></script>
<link rel="styleSheet" href="dtree/dtree.css" type="text/css"/>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<title>左邊的框架頁面</title>

<!-- 定義樹 -->
<script>
    var d=new dTree('d');
    d.config.check=false;    //沒有複選框
    d.config.useIcons =true  //有圖片;
</script>

<style type="text/css">
    *{
        font-size:12px;
        color:black;
    }
</style>
</head>
<body>
    <form  method="post" name="myform">
        <center>
        </center>
            <!-- 遍歷,添加節點; -->
            <c:forEach items="${MeunsList}" var="m">
                 <script>
                    //自己的菜單編號，父節點編號,名稱,鏈接,提示,顯示位置
                    d.add(${m.menusid},${m.menusparent},'${m.menusname}','${m.menusurl}','歡迎使用OA辦公管理系統!','right');
                 </script>
            </c:forEach>

            <!--顯示樹-->
            <script>
                document.write(d);
                d.openAll();
            </script>
    </form>
</body>
</html>
