Spring 事务 - 将 @Transactional 与混合到自定义注释中

发布于 2024-08-29 14:09:07 字数 521 浏览 2 评论 0原文

我的目标是有某种方式将我的服务类声明为事务性的。我不想将其保留为 spring 配置中的显式声明。过去很多时候，我们创建了新服务，却忘记了围绕它们声明交易。因此，我的意图是，如果我有类似 @TransactionalService 自定义注释的内容，它应该执行以下操作：- 1.提供交易支持 2.声明一些Spring当前提供的事务支持的默认规则，如下所示。但与 spring 不同的是，我希望以下内容成为我的 @TransactionService 注释的一部分。

<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<!-- all methods starting with 'get' are read-only -->
<tx:method name="get*" read-only="true"/>
<tx:method name="*"/>

任何建议都会很有价值吗？

My goal is to have some way of declaring my service classes as transactional. I dont want to leave it as an explicit declaration in spring configuration. Many times in past we have created new services and forgot to declare transactions around them. Hence my intention is that if i have something like @TransactionalService custom annotation, it should do the following :-
1. provides transactional support
2. declares some default rules for transactional support as spring currently provides as shown below. But unlike spring, i would like the below to be part of my @TransactionService annotation.

<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<!-- all methods starting with 'get' are read-only -->
<tx:method name="get*" read-only="true"/>
<tx:method name="*"/>

Any advice would be valuable?

当然，您可以将事务服务放在同一个包中，而不是创建新的注释，然后您的切入点（所有事务服务只有一个切入点）将如下所示：

<aop:config>
  <aop:pointcut id="transactionnalServiceMethods" expression="execution(* x.y.transactionnalservice.*.*(..))"/>
  <aop:advisor advice-ref="txAdvice" pointcut-ref="transactionnalServiceMethods"/>
</aop:config>

建议与上面相同：

  <tx:advice id="txAdvice" transaction-manager="txManager">
  <tx:attributes>
    <!-- all methods starting with 'get' are read-only -->
    <tx:method name="get*" read-only="true"/>
    <tx:method name="*"/>
  </tx:attributes>
  </tx:advice>

Sure, instead of creating a new annotation, you could just put your transactionnal services in the same package, and then your pointcut (only one for all you transactionnal services) will look like this :

<aop:config>
  <aop:pointcut id="transactionnalServiceMethods" expression="execution(* x.y.transactionnalservice.*.*(..))"/>
  <aop:advisor advice-ref="txAdvice" pointcut-ref="transactionnalServiceMethods"/>
</aop:config>

The advice is the same as above :

  <tx:advice id="txAdvice" transaction-manager="txManager">
  <tx:attributes>
    <!-- all methods starting with 'get' are read-only -->
    <tx:method name="get*" read-only="true"/>
    <tx:method name="*"/>
  </tx:attributes>
  </tx:advice>
