商城项目加入spring框架

1.加入相应的包:

　　spring所需要的包还是挺多的.除了spring自己的包,还需要aopalliance....aspect...cglib...Commons-logging...Commons-pool...Commons-dhcp...

 

2.在web.xml中的struts2的filter前加入下面两句:

<listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
  
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:bean.xml</param-value>
      </context-param>

3.引入bean.xml..另外为了把Hibernate也交给spring管理,所以把Hibernate.cfg.xml删掉:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

           <context:annotation-config/>        <!-- 允许使用annotation -->
           <context:component-scan base-package="com.shopping" />
           
         <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
                <property name="driverClassName" value="com.mysql.jdbc.Driver"/>

                <property name="username" value="root"/>
                <property name="password" value="1234"/>
                <property name="defaultAutoCommit" value="false" />
              </bean>
           
           <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
                <property name="dataSource" ref="myDataSource"/>
                <!-- 
                <property name="annotatedClasses">
                  <list>
                    <value>com.model.User</value>
                    <value>com.model.Log</value>
                  </list>
                </property>
                 -->
                 <property name="packagesToScan">
                  <list>
                    <value>com.shopping.model</value>
                  </list>
                </property>
                 
                <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                      <prop key="hibernate.show_sql">true</prop>
                      <prop key="hibernate.format_sql">true</prop>
                      <prop key="hibernate.hbm2ddl.auto">update</prop>
          <!--             <prop key="hibernate.current_session_context_class">thread</prop>   -->
                </props>    
                </property>
          </bean>
           
           <bean id="txManager" 
                 class="org.springframework.orm.hibernate4.HibernateTransactionManager">
                <property name="sessionFactory" ref="sessionFactory"/>
          </bean>
           <tx:annotation-driven transaction-manager="txManager"/>
       
           
           <!--   <aop:aspectj-autoproxy />          允许使用aop 的annotation -->
     <!--       
  <bean id="u" class="com.dao.impl.userDAOImpl">
  </bean>
  
  <bean id="userService" class="com.service.userService" init-method="initial" destroy-method="destroy">
    --> 
  
  <!--     <property name="ud" ref="u" />    -->
  <!-- </bean>   -->


</beans>

4.IOC..将所需的容器全部加上@Component..并在相应的set方法加上@Resource..

5.若需要用到日志输出..可以使用aop的切入..
