如何调试Spring AOP [英] How to debug Spring AOP

问题描述

我遇到Spring AOP的问题，它没有将方面与它应该的所有方法联系起来（在我看来）（有关根问题的更多信息，请参阅此问题： Spring AOP忽略了一些Hessian服务方法。

I have a problem with Spring AOP which doesn't ties an aspect to all the methods it should (in my opinion) (see this question for more about the root problem: Spring AOP ignores some methods of Hessian Service).

我如何调试，哪些方法和实例与哪些方面相结合？有没有类似spring aop的详细标志，它提供了这些信息？

How can I debug, what methods and instances get combined with what aspect? Is there something like a verbose flag for spring aop, which gives that information?

推荐答案

似乎没有太多的日志代码在Spring AOP类中，但是......

There seems not to be too much logging code in the Spring AOP classes, but...

如果Spring AOP决定使用Cglib创建代理，那么有一行可以帮助你：

In case Spring AOP decides to use Cglib to create proxy, there's one line which might help you:

    // in org.springframework.aop.framework.Cglib2AopProxy.getProxy(ClassLoader)
    if (logger.isDebugEnabled()) {
        logger.debug("Creating CGLIB2 proxy: target source is " + this.advised.getTargetSource());
    }

当使用JDK代理时，类似的似乎会派上用场：

A similar one seems to come in handy when JDK proxies are used:

    // in org.springframework.aop.framework.JdkDynamicAopProxy.getProxy(ClassLoader)
    if (logger.isDebugEnabled()) {
        logger.debug("Creating JDK dynamic proxy: target source is " + this.advised.getTargetSource());
    }

试着打开这两个类的DEBUG级日志记录，看看是什么输出。

Just try to turn on DEBUG-level logging for these two classes and see what's the output.
