Spring AspectJ loadtimeweaving没有被调用 [英] Spring AspectJ loadtimeweaving not invoked

问题描述

Spring AspectJ加载时织入配置正在构建和加载服务器，而没有任何错误，但是未调用该方面.

The Spring AspectJ loadtime weaving configuration is building and loading server without any errors, but the aspect is not getting invoked.

这是配置列表 1)JDK 8 2)服务器码头

Here is the list of configuration 1) JDK 8 2) Server 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>

还尝试了aop.xml中的选项

Have also tried with options in aop.xml

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() {
    ..
  }
}

使用MAVEN_OPTS设置启动Jetty服务器

Jetty server is started with MAVEN_OPTS setting

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

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

我的行家中有以下依赖项

I have the following dependency in my maven

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aspects</artifactId>
    <version>4.2.0.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-instrument</artifactId>
</dependency>

没有调用SampleAspect.我有几种用@ExecuteByContext注释的方法(公共，私有和受保护).

The SampleAspect is not getting invoked. I have couple of methods (public, private and protected) annotated with @ExecuteByContext.

推荐答案

可能您的目标类不是直接在包com.proj中，而是在子包中.包含子包的语法为..*，而不仅仅是.*，即在您应具有的 aop.xml 中

Probably your target classes are not directly in package com.proj but in a subpackage. The syntax for including subpackages is ..*, not simply .*, i.e. in your aop.xml you should have

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

等等.
