在Spring Boot中抛出NoSuchMethodError的编译时方面

Question

运行我的＆＃34;编译时织女＆＃34;时遇到错误来自Maven的类在我的Spring Boot 1.2.2 WAR中包含的JAR文件中。

所以，我有一个jar，ctms-components.jar，我使用MAVEN运行我的方面（例如，方法时间分析器）。然后，Spring Boot将它全部置于嵌入式WAR中（我使用Tomcat）。我看到了两个aspectj编织类，比如AJC Closures（）等，我看到Maven的日志按照我的切入点编织我的类。

            </dependencies>
        </plugin>

以下是我的maven日志的摘录。

[INFO] Join point 'method-execution(cdot.base.DataAccessObject cdot.ctms.layer.services.comm.device.doppler.facade.DopplerFacade.getDopplerExchange())' in Type 'cdot.ctms.layer.services.comm.device.doppler.facade.DopplerFacade' (DopplerFacade.java:78) advised by around advice from 'cdot.aop.profiler.MethodTimerAspect' (ctms-aspects-2.0.0-SNAPSHOT.jar!MethodTimerAspect.class(from MethodTimerAspect.java))

我的Spring Boot WAR显示AJC Closures捆绑在WAR中：

运行应用程序时得到的错误是：

java.lang.NoSuchMethodError：cdot.aop.profiler.MethodTimerAspect.aspectOf（）Lcdot / aop / profiler / MethodTimerAspect

nested exception is java.lang.NoSuchMethodError: cdot.aop.profiler.MethodTimerAspect.aspectOf()Lcdot/aop/profiler/MethodTimerAspect;

我不明白它为什么编译时编织，把它添加到我的Spring Boot WAR就好了，还包括ctms-aspects.jar，但在我的Aspect上找不到方法？

AspectJ运行时库 aspectjrt.jar 必须位于类路径中，因此它应该是Maven <dependency>，不仅适用于AspectJ Maven插件，还适用于Maven模块。
