先是struts2和hibernate的配置

web.xml:

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

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

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

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <!-- structs2的配置 -->

    <filter>

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

        <filter-class>

            org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

    </filter>

 

    <filter-mapping>

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

        <url-pattern>/*</url-pattern>

    </filter-mapping>

 

</web-app>

 然后在src下添加一个struts.xml:

<?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>
</struts>
 然后在src下添加一个hibernate.cfg.xml：（这是一些数据库的配置）

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC 
 "-//Hibernate/Hibernate Configuration DTD3.0//EN" 
 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<!-- Generated by MyEclipse Hibernate Tools.  -->
<hibernate-configuration>
    <session-factory>
        <property name="connection.username">sa</property>
        <property name="connection.url">
            jdbc:jtds:sqlserver://localhost:1433;DatabaseName=LQQ
        </property>
        <property name="dialect">
            org.hibernate.dialect.SQLServerDialect
        </property>
        <!--<property name="myeclipse.connection.profile">
            LoginSystem
            </property>  -->
        <property name="connection.password">sa</property>
        <property name="connection.driver_class">
            net.sourceforge.jtds.jdbc.Driver
        </property>
        <property name="show_sql">true</property>
        <!-- POJO 类映射配置-->
        <mapping resource="sedion/xq/ORM/Stuinfo.hbm.xml" />
    </session-factory>
</hibernate-configuration>
重点讲Spring：
1. 在src下面新建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" xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<!-- 这是个例子待会会用到  可以先不要 -->
    <bean id="TUser_id" class="test.TUser">
        <property name="username" value="你"></property>
        <property name="allname" value="李"></property>
        <property name="address" value="温州市"></property>
    </bean>
    
</beans>
 然后在web-xml：
<context-param>

         <param-name>contextConfigLocation</param-name>

        <!--spring 的配置文件加载路径-->

          <param-value>classpath:applicationContext.xml</param-value>

</context-param>

2.Spring基本配置完毕

下面我们测试下：src建个test包

建两个类User和SpringTest类:

public class User implements java.io.Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    private String username;
    private String allname;
    private String address;

    public String getUsername() {
        return this.username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getAllname() {
        return this.allname;
    }

    public void setAllname(String allname) {
        this.allname = allname;
    }

    public String getAddress() {
        return this.address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
public class SpringTest {

    public static void main(String[] args) {

        // 加载spring配置文件，初始化IoC容器

        ApplicationContext ac = new ClassPathXmlApplicationContext(

                "applicationContext.xml");

        // 从容器 接管Bean

        TUser user = (TUser) ac.getBean("TUser_id");

        // 输出欢迎信息

        System.out.println("Hello:" + user.getUsername() + ";u is in "

                + user.getAddress() + " ; and u is  " + user.getAllname());

    }

}

<br><br>

在applicationContext.xml中配置一个bean，在xml中增加如下代码：

<!-- 这是个例子  可以先不要 -->

　　<bean id="TUser_id" class="test.TUser">

        <property name="username" value="你"></property>

        <property name="allname" value="李"></property>

        <property name="address" value="重庆市"></property>

    </bean>

运行main方法后

控制台出现：Hello:你;u is in 重庆市 ; and u is  李

下面开始整合

1.整合struts2配置web.xml文件。在web.xml中加入以下代码：

<!-- Spring与Struts的整合其实就是把Struts的Action类交给Spring来管理 -->

<listener>

    <listener-class>

        org.springframework.web.context.ContextLoaderListener  

    </listener-class>

</listener>

2.举个例子：

　　把struts的action交给spring：

　　先把 

<action name="login" class="test.LoginAction ">

改为

<action name="login" class="loginAction_id">

然后在

在applicationContext.xml中增加如下代码：

<bean id="loginAction_id" class="test.action.LoginAction" scope="prototype">
</bean>

在applicationContext.xml中增加如下代码：

 <!-- 配置sessionFactory -->
 
 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
 
     <property name="configLocation">
 
         <value>classpath:hibernate.cfg.xml<alue>
 
     </property>   
 
 </bean>   
  还有个例子上的配置：

<bean id="sessionFactory"

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

        <property name="dataSource" ref="dataSource"></property>

        <property name="hibernateProperties">

            <props>

                <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>

                <prop key="hibernate.show_sql">true</prop>

            </props>

        </property>

        <property name="mappingResources">

            <list>

    　　　　                <value>sedion/xq/bean/User.hbm.xml</value><!--这里是将映射文件加载-->

            </list>

        </property>

 

    </bean>

2.然后DAO层匹配一个session工厂，<ref bean="sessionFactory"/>这个sessionFactory是指session工厂的ID。

<bean id="userDao" class="sedion.xq.dao.iml.UserDAOImpl" scope="singleton">

<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>

3.service层注入DAO层

<bean id="userService" class="sedion.xq.sevice.iml.UserServiceImpl">
<property name="userDAO" ref="userDao"></property>
</bean>
然后就是各个action注入service层：（随便写个）

<bean id="saveUesrAction" class="sedion.xq.action.user.SaveUserAction"
scope="prototype">
<property name="userService" ref="userService"></property>
</bean>
整合就这样好
