第一步：关于web.xml

1.用于struts2的配置，

<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>

2.用于spring的配置，

 <context-param> <param-name>contextConfigLocation</param-name>  // 这个不能随意取名字，必须是这个 <param-value>classpath:applicationContext.xml</param-value> </context-param>

 <listener>

<span style="white-space:pre"></span>//启动Web容器时，自动装配ApplicationContext的配置信息 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>

第二步：关于applicationContext.xml

1.用于hibernate连接数据库的配置，

<bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource">   //这里的class是hibernate的<property name="driverClassName" value="com.mysql.jdbc.Driver"></property><property name="url" value="jdbc:mysql://127.0.0.1:3306/bookshop"></property><property name="username" value="root"></property><property name="password" value="mysql"></property></bean>

<span style="white-space:pre"></span><bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><property name="dataSource" ref="datasource"></property> //利用上边定义好的bean<property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop></props></property><property name="configLocation" value="classpath:hibernate.cfg.xml"></property></bean>

当DAO层用到sessionFactory时，

<pre name="code" class="java">public class UserDAOImp implements UserDAO {SessionFactory sessionFactory;  // 没有使用继承接口的方式public List search(Users user) {Session session = sessionFactory.openSession();Transaction ts = null;/* * Users user1 = new Users(); user1.setPassword("123"); * user1.setUsername("andrew"); */ts = session.beginTransaction();String hql = "from Users where username=? and password=?";Query query = session.createQuery(hql);query.setParameter(0, user.getUsername(),Hibernate.STRING);query.setParameter(1, user.getPassword(),Hibernate.STRING);List<Users> list = query.list();ts.commit();return list;}public SessionFactory getSessionFactory() {return sessionFactory;}public void setSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}}

<bean id="userDAO" class="com.andrew.dao.UserDAOImp"><property name="sessionFactory" ref="sessionFactory"></property></bean>

第三步：关于struts.xml

<package name="default" extends="struts-default"><action name="login" class="userAction" method="login"> //这里的class的value是使用spring配置文件里的bean设置的id<result name="success">main.jsp</result><result name="error">error.jsp</result></action></package>
