如何使用Spring AOP进行AspectJ加载时编织？

标签： java spring aop aspectj spring-aop

我想使用AspectJ Load-Time Weaving来拦截静态方法。我跟着this example。当我执行以下测试时，静态方法被很好地拦截。但是，当我直接运行主类时，它不会被截获。

根据this answer，我测试了所需代理是否通过isAspectJAgentLoaded()充分加载。结果：两种情况都很好。

配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                           http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/context
                           http://www.springframework.org/schema/context/spring-context.xsd">

    <context:load-time-weaver />

</beans>

Aspect类：

@Aspect
public class PerformanceAdvice {

    @Before("execution(* org.springbyexample.aspectjLoadTimeWeaving.MyStaticClass.myStaticClass(..))")
    public void logBefore(JoinPoint joinPoint) {
        System.out.println("*** hijacked : " + joinPoint.getSignature().getName());
    }

}

META-INF / aop.xml文件：

<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
    <weaver>
        <include within="org.springbyexample.aspectjLoadTimeWeaving.*" />
    </weaver>
    <aspects>
        <aspect name="org.springbyexample.aspectjLoadTimeWeaving.PerformanceAdvice" />
    </aspects>
</aspectj>

主要班级：

public class ProcessorRunner { 

    public static void main(String[] args) {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("/application-context.xml", ProcessorRunner.class);
        if (isAspectJAgentLoaded()) System.out.println("*** AspectJ Agent Loaded ***");
        MyStaticClass.myStaticClass();
    }
    public static boolean isAspectJAgentLoaded() {
        try {
            org.aspectj.weaver.loadtime.Agent.getInstrumentation();
        } catch (NoClassDefFoundError | UnsupportedOperationException e) {
            return false;
        }
        return true;
    }
}

测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/application-context.xml"})
public class ProcessorTest { 

    @Test
    public void testProcessorFromContext() {
        if (isAspectJAgentLoaded()) {
            System.out.println("*** AspectJ required agents loaded ***");
        }
        ProcessorRunner.main(new String[]{"myArg"});
    }

    public static boolean isAspectJAgentLoaded() {
        try {
            org.aspectj.weaver.loadtime.Agent.getInstrumentation();
        } catch (NoClassDefFoundError | UnsupportedOperationException e) {
            System.out.println(e);
            return false;
        }
        return true;
    }
}

如果希望的方法与主要课程不同，那么它怎么能在测试课程中被截获？

编辑：如果可以提供帮助，我会添加堆栈跟踪。

答案 0 :(得分：0)

在aspectj-load-time-weaving example中，META-INF/aop.xml文件仅出现在src/tests/resources文件夹中。这就是为什么编织仅在我们执行测试时才起作用。

为了使它在我们直接运行main方法时也能正常工作，我们需要在META-INF/aop.xml文件夹中添加src/java/resources。
