struts2+hibernate+spring

1添加jar包（hibernate+其他jar包）

2修改applicationContext配置文件，通过spring容器管理hibernate

<!--配置数据源 dataSource-->

       <beanid="dataSource"  class="org.springframework.jdbc.datasource.DriverManagerDataSource">  

           <propertyname="url"value="jdbc:oracle:thin:@localhost:1521:orcl"></property>  

           <propertyname="username"value="scott"></property>  

           <propertyname="password"value="tiger"></property> 

           <propertyname="driverClassName"value="oracle.jdbc.driver.OracleDriver"></property>

       </bean>

        <!-- 配置sessionFactory-->

       <beanid="sessionFactory"class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">  

            <propertyname="dataSource">   

                 <refbean="dataSource"/>  

            </property>

              <!-- 读取hibernate配置文件-->

            <propertyname="configLocation"value="classpath:hibernate.cfg.xml"/>

            <propertyname="hibernateProperties">   

                  <props>   

                      <propkey="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>    

                      <propkey="hibernate.hbm2ddl.auto">update</prop>

                  </props>  

            </property>

            <!-- 映射文件 (也可以写在hibernate.cfg.xml配置文件中)-->

            <propertyname="mappingResources">

                 <list>

                       <value>vo/emp.hbm.xml</value>

                 </list>

            </property>

       </bean>

3创建hibernate.cfg.xml

<?xmlversion="1.0"encoding="UTF-8"?>

<!DOCTYPEhibernate-configuration PUBLIC

      "-//Hibernate/HibernateConfiguration DTD 3.0//EN"

      "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

      <hibernate-configuration>

           <session-factory>

                 <propertyname="current_session_context_class">thread</property>

                 <property name="connection.characterEncoding">UTF-8</property>

           </session-factory>

      </hibernate-configuration>

4写dao层

 

 

配置连接池

注意:如果使用的是Spring3.2.*与Hibernate4.3.*会有版本不兼容的问题

 

<beanid="dataSource"class="com.mchange.v2.c3p0.ComboPooledDataSource"> 

        <propertyname="driverClass"value="oracle.jdbc.driver.OracleDriver"> 

        </property> 

        <propertyname="jdbcUrl"value="jdbc:oracle:thin:@localhost:1521:orcl"></property> 

        <propertyname="user"value="scott"/> 

        <propertyname="password"value="tiger"/> 

        <propertyname="minPoolSize"value="10"/> 

        <propertyname="maxPoolSize"value="100"/> 

        <propertyname="maxIdleTime"value="1800"/> 

        <propertyname="acquireIncrement"value="3"/> 

        <propertyname="maxStatements"value="1000"/> 

        <propertyname="initialPoolSize"value="10"/> 

        <propertyname="idleConnectionTestPeriod"value="60"/> 

        <propertyname="acquireRetryAttempts"value="30"/> 

        <propertyname="breakAfterAcquireFailure"value="true"/> 

        <propertyname="testConnectionOnCheckout"value="false"/> 

</bean>

配置事物

修改applicationContext.xml 添加

<!--配置事务管理 -->

     <beanid="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">  

          <propertyname="sessionFactory"ref="sessionFactory"/> 

      </bean>

     <!--配置事务增强-->

    <tx:adviceid="txAdvice"transaction-manager="transactionManager">

        <tx:attributes>

             <tx:methodname="save*"propagation="REQUIRED"/>

               <tx:methodname="delete*"propagation="REQUIRED"/>

               <tx:methodname="update*"propagation="REQUIRED"/>

               <tx:methodname="get*"read-only="true"propagation="NOT_SUPPORTED"/>

               <tx:methodname="*"read-only="true"/>

        </tx:attributes>

    </tx:advice>

    <!--aop配置-->

    <aop:configexpose-proxy="true">

        <aop:pointcutid="pt"expression="execution(*service.*.*(..))"/>

        <aop:advisoradvice-ref="txAdvice"pointcut-ref="pt"/>

</aop:config>

 

注意el中的路径

修改hibernate.cfg.xml
