java - Spring AspectJ loadtimeweaving 未调用

Question

Spring AspectJ 加载时编织配置正在构建和加载服务器，没有任何错误，但方面没有被调用。

这是配置列表1)JDK 82)服务器 jetty

@Configuration
@ComponentScan(basePackages = {..})
@EnableSpringConfigured
@EnableLoadTimeWeaving(aspectjWeaving=AspectJWeaving.ENABLED)
@PropertySource(...)
@ImportResource(value = { "classpath:META-INF/aop.xml", ..})
class config {
...
}

aop.xml

<aspectj>     
      <weaver options="-Xlint:ignore -Xset:weaveJavaPackages=true -Xset:weaveJavaxPackages=true">
        <include within="com.proj.*"/>
        <include within="java.*"/>
        <include within="javax.*"/>
        <include within="org.springframework.*"/>
        <include within="org.aspectj.*"/>
    </weaver>
    <aspects>
        <aspect name="com.proj.SampleAspect"/>
    </aspects>
</aspectj>

还尝试过使用 aop.xml 中的选项

options="-XnoInline -verbose -showWeaveInfo -debug -Xlint:ignore -Xset:weaveJavaPackages=true -Xset:weaveJavaxPackages=true"

方面

@Component
@Aspect
public class SampleAspect {
    @Autowired
    private RequestContextFilter interceptRequestContext;

    @Around("@annotation(ExecuteByContext)")
    public Object interceptByContext(final ProceedingJoinPoint pjp) throws Throwable {
        if(SampleUtil.applyForRequest(interceptRequestContext.getRequestContext()) {
            LOGGER.info(String.format("Intercept context for method %s", pjp.getSignature().getName()));
            return null;
        }
        return pjp.proceed();
    }
}

注释

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface ExecuteByContext {

}

@Component
@Configurable
class TestClass implements ISomeInterface{

  ...
  @ExecuteByContext
  public void method() {
    ..
  }

  @ExecuteByContext
  private void method1() {
    ..
  }
}

Jetty 服务器使用 MAVEN_OPTS 设置启动

-javaagent:/path_to/.m2/repository/org/springframework/spring-instrument/4.2.0.RELEASE/spring-instrument-4.2.0.RELEASE.jar

我的 Maven 中有以下依赖项

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>

SampleAspect 未被调用。我有几个用 @ExecuteByContext 注释的方法(公共(public)、私有(private)和 protected )。

Answer 1

您的目标类可能不直接位于包 com.proj 中，而是位于子包中。包含子包的语法是 ..*，而不是简单的 .*，即在您的 aop.xml 中，您应该有

<include within="com.proj..*"/>

等等。
