这个帖子发了几次，可能都因为太大而没有发成功
但实在是太想和大家分享了 所以就又发上来了，希望大家多多指点。 在我的菜单树中，使用到了struts,spring,hibernate,同时，菜单的生成，在项目中，也基于用户权限动态生成，在这里，只是示例如何处理节点，没有涉及到权限。 （关于权限，设计为这样的结构： create table menu(id varchar(32) primary key not null, name varchar(50) not null, location varchar(255), parentid varchar(32) ) ; create table role_menu (roleid varchar(32) not null, menuid varchar(32) not null); create table role(id varchar(32) not null, name varchar(50) not null, ) 接口如下： package com.myecsun.service.servicelayerinterface;

应大家要求，今天我把里面两个主要的类打包发上来。
其中要用到的包如下： Hibernate3.1.2 Spring1.2.7 Struts-menu2.4 apache collection lang 等 至于Spring的配置和Action的调用，相信大家比我要熟悉的多了：） |

在Spring中的主要配置如下：
<bean id="newscategoryManagerTarget" class="com.myecsun.service.controller.DataDictionary"> <property name="DAO" ref="DAO"></property> </bean> <bean id="newscategoryService" parent="txProxyTemplate"> <property name="target"> <ref local="newscategoryManagerTarget" /> </property> </bean> <bean id="DAO" class="com.myecsun.dbengine.controller.DAOUtils"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> </bean> <bean name="/baseDispatchAction" class="com.myecsun.webengine.controller.BaseDispatchAction"> <property name="service"> <ref bean="service" /> </property> </bean> <bean id="service" class="com.myecsun.service.controller.Service"> <property name="baseService"> <ref local="baseService" /> </property> <property name="menuService"> <ref local="menuService" /> </property> <property name="groupService"> <ref local="groupService" /> </property> <property name="roleService"> <ref local="roleService" /> </property> <property name="userService"> <ref local="userService" /> </property> <property name="newsService"> <ref local="newsService" /> </property> <property name="newscategoryService"> <ref local="newscategoryService" /> </property> </bean> 在Action中的调用方法： HashMap menuSource = getService().getNewscategoryService().buildTreeForDisplay(
"buildTreeForDisplay", new String[] { "id", "name","location",
"parentid" }, request);
MenuRepository mr = (MenuRepository) menuSource
.get(StringPool.MENU_REPOSITORY);
ArrayList parentNodes = (ArrayList) menuSource
.get(StringPool.PARENT_NODES);
HashMap lineTree = (HashMap) menuSource.get(StringPool.LINE_TREE);
