基本配置我就不多说了，网上多的很，我这里只说一下具体实现，呵呵
采用Struts+Hibernate
一、新建菜单表：表根据配置文件自己建吧，我这里就不写了
二、建立表对应的Hibernate的配置文件及JAVABEAN
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--
Mapping file autogenerated by MyEclipse - Hibernate Tools
-->
<hibernate-mapping>
<class name="com.wz.hibernate.Menu" table="menu" catalog="gknews">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="native" />
</id>
<property name="parent" type="java.lang.String">
<column name="parent" not-null="true" />
</property>
<property name="name" type="java.lang.String">
<column name="name" length="45" not-null="true" />
</property>
<property name="target" type="java.lang.String">
<column name="target" length="45" not-null="true" />
</property>
</class>
package com.wz.hibernate;
public class Menu implements java.io.Serializable {
private Integer id;
private String parent;
private String name;
private String target;
/** default constructor */
public Menu() {
}
/** full constructor */
public Menu(String parent, String name, String target) {
this.parent = parent;
this.name = name;
this.target = target;
}
// Property accessors
public Integer getId() {
return this.id;
}
public void setId(Integer id) {
this.id = id;
}
public String getParent() {
return this.parent;
}
public void setParentId(String parent) {
this.parent = parent;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public String getTarget() {
return this.target;
}
public void setTarget(String target) {
this.target = target;
}
}
三、写ActionForm
/*
* Generated by MyEclipse Struts
* Template path: templates/java/JavaClass.vtl
*/
package com.wz.struts_menu.struts.form;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
public class TestMenuForm extends ActionForm {
private String parent;
private String title;
private String target;
private Integer id;
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
// TODO Auto-generated method stub
return null;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
// TODO Auto-generated method stub
}
public String getParent() {
return parent;
}
public void setParentId(String parent) {
this.parent = parent;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getTarget() {
return target;
}
public void setTarget(String target) {
this.target = target;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
四、写Action
/*
* Generated by MyEclipse Struts
* Template path: templates/java/JavaClass.vtl
*/
package com.wz.struts_menu.struts.action;
import java.util.List;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import net.sf.navigator.menu.MenuComponent;
import net.sf.navigator.menu.MenuRepository;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;
import com.wz.hibernate.Menu;
import com.wz.hibernate.MenuItem;
import com.wz.hibernate.SessionFactory;
import com.wz.struts_menu.struts.form.TestMenuForm;
public class TestMenuAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
TestMenuForm testMenuForm = (TestMenuForm) form;// TODO Auto-generated method stub
Session session=SessionFactory.getSession();
//创建事务
Transaction tx=session.beginTransaction();
//创建对话
Query query=session.createQuery("FROM Menu m order by id");
List list=query.list();
//事务提交
tx.commit();
if(list.size()<0)
return mapping.getInputForward();
MenuRepository repository = new MenuRepository();
HttpSession httpsession=(HttpSession)request.getSession();
ServletContext application=(ServletContext)httpsession.getServletContext();
MenuRepository defaultRepository = (MenuRepository)application.getAttribute(MenuRepository.MENU_REPOSITORY_KEY);
repository.setDisplayers(defaultRepository.getDisplayers());
for (int i=0; i < list.size(); i++) {
MenuComponent mc = new MenuComponent();
Menu mi=(Menu) list.get(i);
String name = mi.getName();
mc.setName(name);
String parent = (String) mi.getParentId();
if (parent != null) {
MenuComponent parentMenu = repository.getMenu(parent);
if (parentMenu == null) {
System.out.println("parentMenu '" + parent + "' doesn't exist!");
// create a temporary parentMenu
parentMenu = new MenuComponent();
parentMenu.setName(parent);
repository.addMenu(parentMenu);
}
mc.setParent(parentMenu);
}
String title = (String)mi.getName();
mc.setTitle(title);
String location = (String) mi.getTarget();
mc.setLocation(location);
repository.addMenu(mc);
}
request.setAttribute("repository", repository);
return mapping.findForward("okGo");
}
}
五、写JSP
<%@ page contentType="text/html;charset=UTF-8" language="java"%>
<%@ taglib uri="/WEB-INF/struts-menu.tld" prefix="menu" %>
<%@ taglib uri="/WEB-INF/struts-menu-el.tld" prefix="menu-el" %>
<%@ taglib uri="/WEB-INF/c.tld" prefix="c" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Dynamic, Database-driven Menu</title>
<link rel="stylesheet" type="text/css" media="all"
href="<c:url value="/styles/menuExpandable.css"/>" />
<script type="text/javascript"
src="<c:url value="/scripts/menuExpandable.js"/>"></script>
<link rel="stylesheet" type="text/css" media="all" href="<c:url value="/styles/xtree.css"/>" />
<script type="text/javascript" src="<c:url alue="/scripts/xtree.js"/>"></script>
<link rel="stylesheet" type="text/css" media="all" href="<c:url value="/styles/global.css"/>" />
<script type="text/javascript">
/* Function for showing and hiding elements that use 'display:none' to hide */
function toggleDisplay(targetId) {
if (document.getElementById) {
target = document.getElementById(targetId);
if (target.style.display == "none"){
target.style.display = "";
} else {
target.style.display = "none";
}
}
}
</script>
</head>
<body>
<div class="dynamicMenu">
<menu:useMenuDisplayer name="ListMenu" repository="repository">
<menu:displayMenu name="新浪"/>
<menu:displayMenu name="网易"/>
</menu:useMenuDisplayer>
</div>
</body>
</html>
六、Struts-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
<data-sources />
<form-beans />
<global-exceptions />
<global-forwards >
<forward name="okGo" path="/ok.jsp" />
</global-forwards>
<action-mappings >
<action path="/testAction" type="com.wz.struts_menu.struts.action.TestMenuAction" />
</action-mappings>
<message-resources parameter="com.wz.struts_menu.struts.ApplicationResources" />
<plug-in className="net.sf.navigator.menu.MenuPlugIn">
<set-property property="menuConfig" value="/WEB-INF/menu-config.xml" />
</plug-in>
</struts-config>
这样就算完成了，呵呵；学习中……
