Question

我正在开发我的第一个方面，我遇到了以下麻烦。

MyAspect类：

@Component
@Aspect
public class MyAspect{


@Pointcut("execution(* com.mypackage.MyClass.method(..))")
public void sendComunication(){}

@AfterReturning("sendComunication()")
public void sendComunicationMail() {

    //TODO somethings
}

}

然后我在applicationContext中添加了“aop：aspectj-autoproxy”和aop名称空间。现在，当我尝试构建我的应用程序时，我收到此错误：

我在哪里做错了？

Answer 1

This post暗示您需要升级到aspectj的更新版本。 Get it here

Answer 2

无论你提到什么，都无法找到方面（即“执行（* com.mypackage.MyClass.method（...））”）。方法签名可能是错误的。

Answer 3

我最近遇到了同样的问题。答案是将我们的aspectj版本更改为新版本。就像 Sotirios Delimanolis 所说的那样。

Answer 4

问题在于

com.mypackage.MyClass

不是一个管理到Spring的bean，而是它是vaadin面板中的一个方法

找不到引用的切入点
