Spring 应用程序中的编译时编织无法正常工作

Question

我正在使用 AspectJ 进行编译团队编织，因为加载时间编织相同会导致服务器上的额外开销 startup.so 问题出在编译时所有类都被编织。但是，当在服务器上运行应用程序时，它永远不会进入任何Aspect类。

因此，由于我有一些使用龙目岛的类，所以我这样做并添加了编译时 maven 插件

所以现在就像在编译时一样，它已经编织了所有的类。但在运行时，它不会进入方面.java。还有什么需要添加以进行配置的。？我需要在 spring-config.xml 中添加配置吗？

Answer 1

• 列表项

它通过将切入点更改为：

@Pointcut("execution(* *(..)) && cflow(execution(* com.x.login.LoginMBean.*(..)))")
