AspectJ LTW(编织)不适用于弹簧靴

aspectj spring-boot spring

LppEdd · 技术社区 · 7 年前

我在 Spring Boot 2.1.2.RELEASE - Java 11 - 脂肪罐

根据文件,我有:

将所需的依赖项添加到Gradle构建中

implementation 'org.springframework.boot:spring-boot-starter-aop'
implementation 'org.aspectj:aspectjrt:1.9.2'
implementation 'org.aspectj:aspectjweaver:1.9.2'

启用 LoadTimeWeaving

@SpringBootApplication
@EnableLoadTimeWeaving
public class MyApplication { ... }

提供了 aop.xml 在下面 META-INF

<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
    <weaver>
        <!-- only weave classes in our application-specific packages -->
        <include within="my.base.package.*" />
    </weaver>

    <aspects>
        <!-- weave in just this aspect -->
        <aspect name="my.base.package.spring.aop.MyAspects" />
    </aspects>
</aspectj>

创建了新的 @Aspect 班

@Aspect
public class MyAspects {
    @Around("methodsToBeProfiled()")
    public Object profile(final ProceedingJoinPoint pjp) throws Throwable {
        final var sw = new StopWatch(getClass().getSimpleName());
        try {
            sw.start(pjp.getSignature().getName());
            return pjp.proceed();
        } finally {
            sw.stop();
            System.out.println(sw.prettyPrint());
        }
    }

    @Pointcut("execution(* my.base.package.other.MyClass.*(..))")
    public void methodsToBeProfiled() {}
}

添加了用于检测的jar

-javaagent:/home/myuser/spring-instrument-5.1.5.RELEASE.jar

日志,如你所见,显示 MyAspects 公认的

然而 我的方面 从来没有被实例化(所以没有调试),并且方法也没有被我的方面代码编织。

我错过什么了吗?

编辑:好像两个罐子, aspectjweaver 和 spring-instrument 必须是代理。这正常吗?

你确实需要 aspectjweaver 代理jar。你不需要 spring-instrument (对于胖jar-afaik来说,它曾在应用服务器中用于解决类加载程序的一些历史问题)。你也不需要 @EnableLoadTimeWeaving (也是一个应用服务器功能,如果您控制代理则是多余的)。还有(小麻烦) aspectjrt 是的传递依赖项 AspectJweaver公司 ,所以你不需要两者都有。所以看起来你已经开始工作了,尽管你已经做了比你需要的更多的工作。具有各种编织选项的示例Spring Boot应用程序: here .
