SSH整合示例

1.导入struts,spring,hibernate所需的相应包文件

2.web.xml配置

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

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

  <display-name>SSH</display-name>

  <!--Struts所需的配置 -->

  <filter>

    <filter-name>struts2</filter-name>

    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>

  </filter>

  <filter-mapping>

    <filter-name>struts2</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

   <filter>

    <filter-name>struts-cleanup</filter-name>

    <filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>

  </filter>

  <filter-mapping>

    <filter-name>struts-cleanup</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

    <!--Struts整合Spring所需的配置 -->

  <listener>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

  <listener>

    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>

  </listener>

</web-app>

3.在src中新建struts.xml配置文件

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

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

	<!-- struts2委托spring管理 -->

	<constant name="struts.objectFactory" value="spring" />

	<!-- struts2的包配置 -->

	<package name="demo_action" extends="struts-default">

		<action name="userDetail" class="userDetailBean" method="get">

			<result >/userDetail.jsp</result>

		</action>

	</package>

</struts>

4.在WEB-INF中添加applicationContext.xml文件

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

<beans xmlns="http://www.springframework.org/schema/beans"

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xsi:schemaLocation="

    http://www.springframework.org/schema/beans 

    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd ">

    <!--采用单例形式配置Hibernate的SessionFactory,以classpath形式调用hibernate的配置文件 -->

	<bean id="sessionFactory"

		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

		<property name="configLocation">

			<value>classpath:hibernate.cfg.xml</value>

		</property>

	</bean>

	<!-- 采用单例形式配置Hibernate的transactionManager -->

	<bean id="transactionManager"

		class="org.springframework.orm.hibernate3.HibernateTransactionManager">

		<property name="sessionFactory">

			<ref bean="sessionFactory" />

		</property>

	</bean>

	<!-- userDao的实现者 -->

	<bean id="userDao" class="dao.hibernate.UserDaoHibernate">

		<property name="sessionFactory">

			<ref bean="sessionFactory" />

		</property>

	</bean>

	<!-- Id与struts.xml配置的class相同，此处的Class为真实的Class -->

	<bean id="userDetailBean" class="action.UserAction" scope="prototype">

		<property name="userDao">

			<ref bean="userDao" />

		</property>

	</bean>

</beans>

5.userDao类

package dao;

import java.util.List;

import entites.Userinfo;



public interface UserDao {

	public abstract Userinfo get(int userId);

}

6.userDao接口实现者

package dao.hibernate;

import java.util.List;

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

import dao.UserDao;

import entites.Userinfo;



public class UserDaoHibernate extends HibernateDaoSupport implements UserDao {

	@Override

	public Userinfo get(int userId) {

		return (Userinfo) getHibernateTemplate().get(Userinfo.class, userId);

	}

｝

7.Struts的Action类UserAction

package action;



import java.util.Date;

import java.util.List;

import java.util.Map;

import com.opensymphony.xwork2.ActionContext;

import com.opensymphony.xwork2.ActionSupport;

import dao.UserDao;

import entites.Userinfo;



public class UserAction extends ActionSupport {

	private UserDao userDao;



	public void setUserDao(UserDao dao) {

		userDao = dao;

	}

	public String get()

	{

		Userinfo userinfo=userDao.get(40);

		setUserInfo(userinfo);

		return super.SUCCESS;

	}

｝

8.视图文件userDetail.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<title>Insert title here</title>

<style type="text/css">

table {

	border: 1px solid black;

	border-collapse: collapse;

}



table tbody tr td {

	border: 1px solid black;

	padding: 3px;

}

</style>

</head>

<body>

UserDetail

<table>

<tr><td>UserName:</td><td>${requestScope.UserInfo.userName}</td></tr>

<tr><td>PassWord:</td><td>${requestScope.UserInfo.password}</td></tr>

</table>

</body>

</html>

9.hibernate.cfg.xml文件

<?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">

<hibernate-configuration>

    <session-factory>

        <property name="hibernate.bytecode.use_reflection_optimizer">false</property>

        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

        <property name="hibernate.connection.password">111</property>

        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/javadb</property>

        <property name="hibernate.connection.username">root</property>

        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

        <mapping resource="entites/Userinfo.hbm.xml" />

    </session-factory>

</hibernate-configuration>

10.Userinfo.hbm.xml文件

<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
