spring + hibernate 配置事务

spring + hibernate 配置事务

上次折腾了半天，终于把延时加载配置好了。可是不配置事务总是觉得怪怪的。so..决定把事务也配置好。虽然是个小项目吧^_^.

<!--  事务配置  -->
      <!--  事务管理器 用于hibernate的事务管理器 -->
       < bean  id ="transactionManager"  class ="org.springframework.orm.hibernate3.HibernateTransactionManager" >
         < property  name ="sessionFactory" >
             < ref  bean ="sessionFactory" />
         </ property >
     </ bean >
    
     <!--  事务拦截器 用于对拦截的方法开启事务,其中指定了一些只读事务 -->
     < bean  id ="transactionInterceptor"  class ="org.springframework.transaction.interceptor.TransactionInterceptor" >
         < property  name ="transactionManager"  ref ="transactionManager" />
         < property  name ="transactionAttributes" >
             < props >
                 < prop  key ="*" > PROPAGATION_REQUIRED,-Exception </ prop >
                 < prop  key ="list*" > PROPAGATION_REQUIRED,readOnly </ prop >
                 < prop  key ="*list" > PROPAGATION_REQUIRED,readOnly </ prop >
                 < prop  key ="display*" > PROPAGATION_REQUIRED,readOnly </ prop >
                 < prop  key ="*display" > PROPAGATION_REQUIRED,readOnly </ prop >
                 < prop  key ="*view" > PROPAGATION_REQUIRED,readOnly </ prop >
                 < prop  key ="find*" > PROPAGATION_REQUIRED,readOnly </ prop >
                 < prop  key ="main*" > PROPAGATION_REQUIRED,readOnly </ prop >
             </ props >
         </ property >
     </ bean >
    
     <!--  自动代理，配置使所有service层bean使用事务拦截器  -->
     < bean  class ="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator" >
         < property  name ="beanNames" >
             < list >
             < value > *Service </ value >
             </ list >
         </ property >
         < property  name ="interceptorNames" >
             < list >
                 < value > transactionInterceptor </ value >
             </ list >
         </ property >
     </ bean >

     < bean  class ="org.springframework.transaction.interceptor.TransactionAttributeSourceAdvisor" >
         < property  name ="transactionInterceptor"  ref ="transactionInterceptor" />
     </ bean >
     <!--  事务配置结束  -->

简单说明一下，其中是用了spring提供的 BeanNameAutoProxyCreator这个自动代理服务，自动对名为XXXService的的bean使用使用拦截器开启事务，而在 transactionInterceptor 则定义了事务的属性，限定了一些只读的事务以提搞效率。
