• Struts+Spring+HibernateSSH整合实例


    Struts+Spring+Hibernate--SSH整合实例:

    网上虽然有很多SSH整合的小例子,但很多程序都出现了不是这样,就是那样的错误。自己总结了一下,终于做出的Struts+Spring+Hibernate整合的小例子,也是最基础的SSH实例,虽然是小例子,但什么程序都是从基础的做起。如果你弄明白了这个小实例,相信你的SSH整合框架技术也会提高很多。

           在做本例前,需要熟悉对StrutsHibernate的反向工程等的基本操作。

    开发工具:MyEclipse+MySQL+Tomcat

    说明:本实例是简单注册程序(只有两个属性)

    数据库脚本:user.sql

    DROP TABLE IF EXISTS `user`;

    CREATE TABLE `user` (

    `Id` int(11) NOT NULL AUTO_INCREMENT,

    `username` varchar(255) DEFAULT NULL,

    `password` varchar(255) DEFAULT NULL,

    PRIMARY KEY (`Id`)

    ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

     

    开发步骤:

    1建立Web项目

       选择: Java EE 5.5

    2添加Struts支持(项目右键àMyEclipse Struts Capabilities …

           选择:

    1Struts specification Struts 1.3

    2Base package for 那位classesedu.syict.struts

    3添加Spring支持(项目右键àMyEclipse Spring Capabilities …

           选择:

    1) Spring versionSpring 2.0

    2) Select the libraries to add the buildpath

    Spring 2.0 AOP Libraries

    Spring 2.0 Core Libraries

    Spring 2.0 Persistence Core Libraries

    Spring 2.0 Persistence JDBC Libraries

    Spring 2.0 Web Libraries

           3) JAR Library Installation

    Copy checked Library contents to project folder TLDs always copied

           Next

    4) Spring配置文件选择目录FolderWebRoot/WEB-INF

    Finish

    4 添加Hibernate支持(项目右键àMyEclipse Hibernate Capabilities …

           选择:

           1Hibernate SpecificationHibernate3.1

           2Select the libraries to ad to the buildpathHibernate 3.1 Core Libraries

    3JAR Library InstallationCopy checked Library Jars to project folder and add to build-path

    Next

    4)选择:Spring configuration file(applicationContext.xml) Next

           5)选择:Existing Spring configuration file

    SessionFactory Id sessionFactory àNext

           6Bean IddataSource

    DB Driver:选择配置好的HibernateàNext

           7)不建立SessionFactory(不选择Create SessionFactory class?

           8Finish

    数据库方面

           1)建立包edu.syict.pojo

    Hibernate反向工程:

              选择下列内容:

    Create POJO<>DB Table mapping information复选框

                         Create a Hibernate mapping file单选框

                         Update Hibernate configuration with mapping resource location复选框

                Java Data ObjectPOJO<>DB Table)复选框  

                其余的都不选择。àNext          

    Id Generatornative àFinish

     

           2)新建接口:edu.syict.dao.UserDao.java (所在包:edu.syict.dao )

    package edu.syict.dao;

    import edu.syict.pojo.User;

    public interface UserDao {

        public void save(User user);

    }

           3)建立UserDao接口实现类edu.syict.dao.impl.UserDaoImpl

           类继承HibernateDaoSupport,接口继承UserDao

    package edu.syict.dao;

    import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

    import edu.syict.pojo.User;

    public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

        public void save(User user) {

           try{

               this.getHibernateTemplate().saveOrUpdate(user);

           }catch(RuntimeException re){

               throw re;

           }

        }

    }

    建立JSP 页面,Action

           1) 打开struts-config.xml配置文件:右键new àForm,Action and JSP

           2) User caseregister

           Form ImplDynamic FormBean

           Propertiesusername password

           JSP:选择Create JSP form àNext

    3) Action 默认就可以了 àFinish

           4) 配置struts-config.xml文件,将Struts交给Spring管理

                  a) 加入插件 (message-resources标记下)

    <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">

        <set-property property="contextConfigLocation"

                  value="/WEB-INF/applicationContext.xml" />

    </plug-in>

    b) Action类移交(message-resources标记上)

    <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/>

           struts-config.xml文件(全部)

           struts-config.xml文件(全部)

    <?xml version="1.0" encoding="UTF-8"?>

    <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd">

     

    <struts-config>

    <form-beans >

        <form-bean name="registerForm" type="org.apache.struts.action.DynaActionForm">

          <form-property name="password" type="java.lang.String" />

          <form-property name="username" type="java.lang.String" />

        </form-bean>

    </form-beans>

     

    <global-exceptions />

    <global-forwards />

    <action-mappings >

        <action

          attribute="registerForm"

          input="/form/register.jsp"

          name="registerForm"

          path="/register"

          scope="request"

          type="edu.syict.struts.action.RegisterAction" />

    </action-mappings>

    <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/>

    <message-resources parameter="edu.syict.struts.ApplicationResources" />

    <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">

        <set-property property="contextConfigLocation"

                  value="/WEB-INF/applicationContext.xml" />

    </plug-in>  

    </struts-config>

    5) register.jsp页面(WebRoot/form/register.jsp)

    <%@ page language="java" pageEncoding="UTF-8"%>

    <%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>

    <%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>

     

    <html>

        <head>

           <title>用户注册</title>

        </head>

        <body>

        SSH整合<br><hr>

        <h3>用户注册</h3>

           <html:form action="/register">

               用户名:<html:text property="username"/><html:errors property="username"/><br/>

               &nbsp;&nbsp;&nbsp;&nbsp;码:<html:text property="password"/><html:errors property="password"/><br/>          

               <html:submit value="注册"/>&nbsp;&nbsp;&nbsp;&nbsp;<html:reset value="重置"/>

           </html:form>

        </body>

    </html>
