java - Spring @Transactional 属性是否适用于私有(private)方法？

Question

如果我有 @Transactional -对Spring bean中的私有(private)方法进行注解，注解有什么作用吗？

如果 @Transactional 注释在公共(public)方法上，它会起作用并打开一个事务。

public class Bean {
  public void doStuff() {
     doPrivateStuff();
  }
  @Transactional
  private void doPrivateStuff() {

  }
}

...

Bean bean = (Bean)appContext.getBean("bean");
bean.doStuff();

您的问题的答案是否定的 - 如果用于注释私有(private)方法，@Transactional 将无效。代理生成器将忽略它们。

这在 Spring Manual chapter 10.5.6 中有记录:

Method visibility and @Transactional

When using proxies, you should apply the @Transactional annotation only to methods with public visibility. If you do annotate protected, private or package-visible methods with the @Transactional annotation, no error is raised, but the annotated method does not exhibit the configured transactional settings. Consider the use of AspectJ (see below) if you need to annotate non-public methods.
