AspectJ Spring Boot未编织aop中包含的类。xml

Question

我在使用LoadTimeWiven策略将AspectJ与SpringBoot集成时遇到了很多问题（因为SpringAOP不适合我的情况）。

我配置了以下许多指南AspectJ。以下是我在与pom AspectJ相关的

    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjrt</artifactId>
        <version>${ascpectj.version}</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-instrument</artifactId>
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>
        <version>${ascpectj.version}</version>
    </dependency>

这是我的aop。xml

<aspectj>


    <weaver options="-showWeaveInfo -debug -Xlintfile:pathToAResource -verbose">
        <include within="foo.*"/>
    </weaver>


    <aspects>
        <aspect name="org.springframework.beans.factory.aspectj.AnnotationBeanConfigurerAspect"/>
        <aspect name="org.springframework.scheduling.aspectj.AnnotationAsyncExecutionAspect"/>
        <aspect name="org.springframework.transaction.aspectj.AnnotationTransactionAspect"/>
        <aspect name="org.springframework.cache.aspectj.AnnotationCacheAspect"/>
        <aspect name="it.poste.energy.aspects.TaskAspect"/>
    </aspects>

</aspectj>

我确信它在项目结构中的位置是正确的，因为它实际上是在读取weaver标记中传递的选项（我知道xlintoption显然不正确，但我认为现在它并不重要）java

我在基本配置类上配置了自定义LoadTimeWeaver，如下所示：

@Configuration
@EnableLoadTimeWeaving(aspectjWeaving = AspectJWeaving.ENABLED)
public class CustomLoadTimeWeaverConfig implements LoadTimeWeavingConfigurer {

    @Override
    @NonNull
    public LoadTimeWeaver getLoadTimeWeaver() {
        return new TomcatLoadTimeWeaver();
    }

    @Bean
    public InstrumentationLoadTimeWeaver loadTimeWeaver()  throws Throwable {
        return new InstrumentationLoadTimeWeaver();
    }

}

然后，我启动Spring应用程序，传递以下2个用于java代理的vm参数-javaagent： C：\用户\foo-user. m2\repository\org\aspectj\aspectjweaver\1.9.6\aspectjweaver-1.9.6.jar-javaagent： C：\用户\foo-user. m2\repository\org\springFramework\spring-Instrt-5.2.10。RELEASE\spring-Instrt-5.2.10。RELEASE. jar

（我尝试删除Spring仪器的地方建议和EnableLoadTimeWeave注释，但没有改变）

该应用程序启动良好，但它并没有在aop中编织一个包含包的类。xml。这是weaver调试日志的一个示例

    [URLClassLoader@1efee8e7] debug not weaving 'foo.energy.domain.client.crmu.Foo1'
    [URLClassLoader@1efee8e7] debug not weaving 'foo.energy.domain.client.crmu.Foo2'
    [URLClassLoader@1efee8e7] debug not weaving 'foo.energy.domain.client.Foo3'
    [URLClassLoader@1efee8e7] debug not weaving 'fooo.energy.domain.client.Foo4'

让我感到困扰的是，它正确地注册了所有方面，因此：

[InspectionClassLoader@3db65c0d] info AspectJ Weaver Version 1.9.6 built on Tuesday Jul 21, 2020 at 13:30:08 PDT

问题是这些最后一行日志（方面的注册）被调用了3/4次，我不知道它是否异常或什么

我错过什么了吗？

SN：我正在使用Spring Boot v2.3.5。RELEASE，Spring v5.2.10。对于aspectjrt和aspectjweaver，RELEASE和tomcat 9.0.39和1.9.6

Answer 1

请注意，foo.*仅直接匹配foo包中的类，而不是子包中的类。为此，您需要foo...*。因此，您应该替换

<include within="foo.*"/>

通过

<include within="foo..*"/>

我想知道为什么这么多指南使用com.*来编织子包。

我称这种现象为“复制”
