SSH整合

整合原理

整合步骤

1.添加struts框架

struts所需jar包：

2.添加spring框架

spring所需jar包：

3.添加hibernate框架

4.目录结构

添加完框架的目录结构

整合项目的目录结构

5.hibernate.xml中配置数据源

<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-configuration PUBLIC          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools.                   --><hibernate-configuration><session-factory><property name="dialect">org.hibernate.dialect.Oracle9Dialect</property><property name="connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property><property name="connection.username">Scott</property><property name="connection.password">tiger</property><property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property><property name="myeclipse.connection.profile">SCOTT</property><property name="show_sql">true</property><property name="format_sql">true</property><mapping resource="pojo/Project.hbm.xml" /><mapping resource="pojo/Vote.hbm.xml" /><mapping resource="pojo/Tuser.hbm.xml" /></session-factory></hibernate-configuration>

6.applicationContext.xml配置

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd"><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="configLocation" value="classpath:hibernate.cfg.xml"></property></bean><!--  装配HibernateTemplate  --><bean id="hibernateTemplateId" class="org.springframework.orm.hibernate3.HibernateTemplate"><property name="sessionFactory" ref="sessionFactory"></property></bean><bean id="tuserDao" class="dao.impl.TuserDao"><property name="hibernateTemplate" ref="hibernateTemplateId"></property></bean>        <bean id="voteDao" class="dao.impl.VoteDao">        <property name="hibernateTemplate" ref="hibernateTemplateId"></property>     </bean>         <bean id="pojectDao" class="dao.impl.ProjectDao">        <property name="hibernateTemplate" ref="hibernateTemplateId"></property>     </bean> </beans>

7.struts.xml配置

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts>    <constant name="struts.devMode" value="false" />    <constant name="struts.i18n.encoding" value="UTF-8" />    <package name="sysPack" extends="struts-default" namespace="/system">        <action name="tuserAction" class="action.TuserAction">            <result name="adminLogin" type="redirect">/admin.jsp</result>            <result name="userLogin" type="redirect">/index.jsp</result>            <result name="loginFail" type="redirect">/loginFail.jsp</result>            <result name="register" type="redirect">/index.jsp</result>            <result name="exit" type="redirect">/index.jsp</result>        </action>        <action name="voteAction" class="action.VoteAction">            <result name="selectList">/adminVoteList.jsp</result>            <result name="updateVote">/updateVote.jsp</result>            <result name="execute">/index.jsp</result>            <result name="userSelectList">/userVoteList.jsp</result>        </action>        <action name="projectAction" class="action.ProjectAction">            <result name="selectList">/adminProjectList.jsp</result>            <result name="addProject">/addProject.jsp</result>            <result name="userSelectList">/userProjectList.jsp</result>        </action>    </package></struts>    

8.代码实现

TuserDao中的部分代码展示

package dao.impl;import hibernate.HibernateSessionFactory;import java.util.Date;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.Transaction;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import pojo.Tuser;import dao.inf.TuserDaoInf;public class TuserDao extends HibernateDaoSupport implements TuserDaoInf {@Overridepublic void addUser(Tuser tuser) {Session session = HibernateSessionFactory.getSession();Transaction transaction = session.beginTransaction();session.save(tuser);transaction.commit();}@Overridepublic Tuser selectUser(Tuser tuser) {Session session = HibernateSessionFactory.getSession();String hql = "from Tuser where name = '" + tuser.getName() + "'";Query query = session.createQuery(hql);Tuser tuser2 = (Tuser) query.uniqueResult();session.close();return tuser2;}@Overridepublic void deleteUser(Tuser tuser) {}@Overridepublic void updateUser(Tuser tuser) {}}

说明：这种整合方法简单易懂，适合初学者理解SSH整合中，各个框架在项目中起到的作用
