Spring Can'；找不到引用的切入点

我正在开发我的第一个方面，我遇到了以下问题

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，当我尝试构建应用程序时，出现以下错误：

我哪里做错了？

提示您需要升级到aspectj的更新版本

问题是

com.mypackage.MyClass

---

不是一个bean成功地启动了，而是vaadin面板中的一个方法

它无法找到您提到的方面（即“execution（*com.mypackage.MyClass.method（..）”）。方法签名可能是错误的。

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

您添加了组件扫描吗？我不确定这是否重要。是的，我添加了组件扫描。你能发布跟踪吗？这不会改变你得到的错误。创建时不需要应用

@Aspect

。当Spring尝试创建

@Aspect

但找不到与

sendCommunication（）

匹配的

@Pointcut

时，会发生故障。抱歉。这是我第一次发布答案。
