Spring框架中的加载时间编织不能正确记录日志

Question

对于使用JSF作为用户界面并包含6k+类的企业级应用程序来说，加载时编织(LTW)是一个很好的选择吗？必须为整个应用程序生成性能指标，但不能为LoginMBean等JSF托管Bean生成性能指标。然而，@Component是存在的，所以它有可能与AspectJ(LTW)一起工作吗？将添加aop.xml，并将aspectJWeaver路径添加到vm参数。

LoginMBean是为login.xhtml管理的jsf。是JSF问题还是因为错误的切入点？LoginMBean没有出现在编织类中。请帮助上面的错误。我无法获得LoginMBean类中任何方法的性能指标。

查看您的日志，看起来LoginMBean没有公开给AspectJ编织器。至少我没有看到任何weaveinfo ... in Type 'com.x.login.LoginMBean'。所以

• 要么装入并编织类(您可以在确定类已装入并由weaveinfo.*LoginMBean使用之后，将您的日志grep到日志下面)
• ，要么根本不编织(如果您找不到这样的日志条目)。那么你就有了一个类加载器的问题，例如，不知何故，负责加载LoginMBean的类加载器上没有注册AspectJ编织代理。那么知道您正在使用哪个应用程序服务器以及命令JVM行是什么样子将会很有趣(应该是-javaagent:....
