问题描述
我最近遇到了一个问题，在这个问题中，我的web应用程序无法正常启动，并且堆栈跟踪没有完全指示发生了什么。我已经能够将它隔离为我写的一个事件监听器。无论何时我尝试激活它，我都会得到一个非常通用的异常：

现在，我在过去遇到了这个问题，这是由于我试图通过让setter和获得者决赛。 Hibernate需要为实体类设置代理，因此它可以延迟加载内容，所以如果我最终设置了setter / getter，它就不能这样做。
事件我希望使用的侦听器基本上侦听持久性和更新事件。当发生这种情况时，它应该将当前日期设置为使用相应注释标注的字段，以将该字段标记为需要设置当前日期。
我是认为这是因为我正在运行更新版本的javassist：
javassist：javassist：jar：3.11.0.GA：runtime
有没有人遇到过这个问题？
我在Jetty 7上运行JBoss Seam 2.2.0.GA。

解决方案
好吧，我没有得到任何好的答案。在这个特定的情况下，我遇到了问题，问题是我的依赖关系配置的版本不正确。这是让我的项目和现在一样多的负面因素之一。我必须密切关注我在每个项目中使用的版本。
在其他情况下，我觉得我遇到了Lucene配置问题。在这两种情况下，我都希望看到堆栈跟踪，以便我可以查看它，然后，哎呀，我有一个坏jar或类似的东西。

I have been recently running into an issue in which my web application will not start properly and the stack trace doesn't indicate exactly what happened. I have been able to isolate it to an event listener that I wrote. Whenever I attempt to activate it, I get a very generic exception:

Now, I had this problem in the past, and that was caused by me trying to over optimize each entity class by making the setters and getters final. Hibernate needs to setup proxying for the entity classes so it can lazy load stuff, so if I make a setter/getter final, it can't do that.
The event listener I want to use essentially listens for persist and update events. When one happens, it is supposed to set the current date on a field annotated with the corresponding annotation to mark the field as requiring a current date to be set.
I am thinking that this is because I am running a newer version of javassist:
javassist:javassist:jar:3.11.0.GA:runtime
Has anyone run into this issue before?
I am running JBoss Seam 2.2.0.GA on Jetty 7.

解决方案
Well, I didn't really get any good answers. In this particular instance that I had the problem, the problem was having an incorrect version of my dependencies configured. That is one of the negatives with having my projects split up as much as they are. I have to pay close attention to which version I'm using in each project.
In other cases, it seemed to me that I had issues with a Lucene configuration. In either case, I would prefer to see the stack trace so I can look at it and then, oops, I have a bad jar or something like that.
