spring+struts2+hibernate整合

web.xml需要配置

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

db.properties

jdbc.user=root
jdbc.password=tiger
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql:///ssh
 
jdbc.initPoolSize=5
jdbc.maxPoolSize=10

applicationContext.xml

<context:property-placeholder location="classpath:db.properties" />
 
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="user" value="${jdbc.user}"></property>
        <property name="password" value="${jdbc.password}"></property>
        <property name="driverClass" value="${jdbc.driverClass}"></property>
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
 
        <property name="initialPoolSize" value="${jdbc.initPoolSize}"></property>
        <property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property>
    </bean>
 
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
        <property name="mappingLocations" value="classpath:com/my/ssh/entities/*.hbm.xml"></property>
    </bean>
 
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
 
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="get*" read-only="true"/>
            <tx:method name="isValidate" read-only="true"/>
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>
 
    <aop:config>
        <aop:pointcut expression="execution(* com.my.ssh.service.*.*(..))" id="pointCut"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/>
    </aop:config>

applicationContext-beans.xml

　　配置各种bean  注意:对于Struts2 的Action类  scope 需要配置为prototype (不为单例)

<bean id="employeeAction" class="com.my.ssh.actions.EmployeeAction" scope="prototype">
　　<property name="employeeService" ref="employeeService"></property>
　　<property name="departmentService" ref="departmentService"></property>
</bean>

hibernate.cfg.xml

<hibernate-configuration>
    <session-factory>
　　　　<!-- 配置基本信息-->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.format_sql">true</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
 
        <!-- 二级缓存 -->
 
    </session-factory>
</hibernate-configuration>

struts.xml

<!-- 只需要把class 配置为 在applicationContext-beans.xml 文件中Action所指向的id-->
<action name="emp-*" class="employeeAction" method="{1}">
 
</action>
