Spring MVC项目编译警告

Question

所有内容都会编译，但会显示以下警告：

Warning: advice defined in org.springframework.mock.staticmock.AnnotationDrivenStaticEntityMockingControl has not been applied [Xlint:adviceDidNotMatch]

Warning: advice defined in org.springframework.mock.staticmock.AbstractMethodMockingControl has not been applied [Xlint:adviceDidNotMatch]

Warning: advice defined in org.springframework.scheduling.aspectj.AbstractAsyncExecutionAspect has not been applied [Xlint:adviceDidNotMatch]

Warning: advice defined in org.springframework.orm.jpa.aspectj.JpaExceptionTranslatorAspect has not been applied [Xlint:adviceDidNotMatch]

有人能解释一下它们的确切含义吗？

Answer 1

这是您的编译时AspectJ编织过程的输出-它显示了您的代码库中还没有应用哪些AspectJ建议。

进一步扩展一下- Spring相关的方面通常在spring-aspects.jar文件的META-INF/aop.xml文件中定义，这些方面基于与代码库中匹配的切入点被编织到您的类中，如果某个切入点不匹配，例如，您可能在任何地方都没有任何@Async注释，那么建议不会被应用，您将看到advice defined in org.springframework.scheduling.aspectj.AbstractAsyncExecutionAspect has not been applied的消息
