spring配置时的bean注入

1.事务管理：每个Bean都有一个代理(比较笨拙的配置)

     dataSource 注入进sessionFactory,将sessionFactory注入到transactionManager(org.springframework.orm.hibernate3.HibernateTransactionManager这是一个事务管理器，声明式事务), 再注入userService(TransactionProxyFactoryBean实现spring声明式事务)userService的属性transactionManager是为事务代理bean注入事务管理器如：

(用其他例子来说明)

2.spring的bean注入：

          <!--sessionFactory注入到事务管理器中--><bean id="transactionManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property></bean>        <!--sessionFactory注入到dao层 ,同时dao层要设置成单例--><bean id="userDao" class="com.test.dao.impl.UserDAOImpl" scope="singleton"><property name="sessionFactory"><ref bean="sessionFactory" /></property></bean><bean id="userServiceTarget" class="com.test.service.impl.UserServiceImpl"><property name="userDao" ref="userDao"></property></bean>       <!--将配置有事务userService注入到SshWsImpl类 userServiceTarget属性中--><bean id="IsshWs" class="com.test.wsservice.impl.SshWsImpl"><property name="userServiceTarget" ref="userService"></property></bean><jaxws:endpoint implementor="#IsshWs" address="/cxfssh.ws"></jaxws:endpoint><bean id="userService"class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"><property name="target" ref="userServiceTarget"></property><property name="transactionManager" ref="transactionManager"></property><property name="transactionAttributes"><props><prop key="find*">PROPAGATION_REQUIRED,readOnly</prop><prop key="*">PROPAGATION_REQUIRED</prop></props></property></bean>///sessionFactory注入到dao层，dao注入到service层，service层配置好事务注入到action层或是接口层，完成。///sessionFactory注入到事务管理器transactionManager，transactionManager再注入到TransactionProxyFactoryBean，完成事务配置。
