Struts-menu 权限控制

Struts-menu 权限控制<一>

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>

</hibernate-mapping>

package com.wz.hibernate;

 

publicclass Menu implements java.io.Serializable {

 

     private Integer id;

     private String parent;

     private String name;

     private String target;

 

    /**defaultconstructor*/

    public Menu() {

    }

    /**fullconstructor*/

    public Menu(String parent, String name, String target) {

        this.parent = parent;

        this.name = name;

        this.target = target;

    }  

    // Property accessors

    public Integer getId() {

        returnthis.id;

    }   

    publicvoid setId(Integer id) {

        this.id = id;

    }

    public String getParent() {

        returnthis.parent;

    }   

    publicvoid setParentId(String parent) {

        this.parent = parent;

    }

    public String getName() {

        returnthis.name;

    }   

    publicvoid setName(String name) {

        this.name = name;

    }

    public String getTarget() {

        returnthis.target;

    }   

    publicvoid 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" %>
