【问题描述】：
是否可以将方面应用于 Maven 依赖项？我的项目中还有其他方面可以正常工作，但是当我尝试将其应用于@Slf4j 记录器时，它会被跳过。我通过调试并进入 log.info 调用确定切入点是ch.qos.logback.classic.Logger.*，但它仍然不会触发方面。是否有在依赖项上启用它的设置？
其他注释掉的切入点是我尝试过的切入点，但它们要么导致 bean 无法创建（它们没有资格被 bean 后处理器处理），要么什么都不做。
@Aspect
@Component
public class LoggingAspect {
@Around("execution(* ch.qos.logback.classic.Logger.*(..))"// && " +
// "execution(* lombok.*(..)) && " +
// "execution(* org.slf4j.*(..)) && " +
// "execution(* org.slf4j.Logger.*(..)) "
)
public Object prependBridgeRunId(ProceedingJoinPoint jp) throws Throwable {
//get original args
Object[] args = jp.getArgs();
for (int i = 0; i < args.length; i++) {
Object raw = args[i];
if (raw instanceof String) {
// and replace it with a new value
args[i] = "{\"bridgeRunId\": " + GlobalConstants.getBridgeRunId() + "}" + raw;
}
}
//execute original method with new args
return jp.proceed(args);
}
}

【问题讨论】：
-
是的，有可能。请按照我已经在 GitHub 上给你的建议向我展示你的 POM。我想看看到目前为止你是如何编译你的方面的，然后我可以告诉你增量。我还想知道您当前使用的是基于代理的 Spring AOP 还是本机 AspectJ，因为使用 Spring AOP，您想要的东西是不可能的，而使用 AspectJ 您可以做到。理想情况下，将MCVE 推送到 GitHub，这样我也可以看到您的 Spring 配置。像这样，悬而未决的问题太多了。
-
@kriegaex 由于@Slf4j/logback 没有注册为Spring bean，我认为我不能使用spring aspectj。所以我试图使用原生的 AspectJ。但它似乎没有用。 p.s.添加了 POM
-
我会尝试让 MCVE 正常工作，谢谢您的帮助！

我已经写了一个通用答案，解释了一些基础知识。有了 MCVE，我就可以更具体，直接解决您的问题。
