如何使用Eclipse查找在Java中引发异常的类

Question

我陷入了Java Spring MVC应用程序中发生的异常。 控制台中显示以下内容：

22:17:55.614 [http-nio-8080-exec-8] ERROR o.h.util.JDBCExceptionReporter - Batch entry 0 update public.wc_content_definition set web_content_desc= was aborted. Call getNextException() to see the cause.

我无法找到引发异常的确切方法。 有什么方法可以找到此消息的来源方法或类。

Answer 1

通常 ，异常的确切原因是在堆栈跟踪的第一行 ，有关该异常原因的更多信息，您需要逐步向下移动 ，并且根本原因通常可以在堆栈底部附近找到跟踪。

但是在大多数情况下，您甚至可以从前几行获得异常原因。

我从上到下阅读了您的堆栈跟踪记录，

这是实际上引发异常的行...

 at com.smartwcm.core.userprofile.dao.impl.UserProfileDaoImpl.getUserProfile(UserProfileDaoImpl.java:40) [UserProfileDaoImpl.class:na]

因为上面的所有行都与休眠有关，但是此行特定于您的应用程序。

Answer 2

当您阅读堆栈跟踪时，查找您的代码包的第一次出现。

通过查看提供的跟踪信息： org.hibernate.exception ， org.hibernate.jdbc和org.hibernate.impl查找标准的API包。

因此最有可能在com.smartwcm.core.userprofile.dao.impl.这些行com.smartwcm.core.userprofile.dao.impl. 是您自己定义的程序包， 行号40 UserProfileDaoImpl.getUserProfile （UserProfileDaoImpl.java:40）是罪魁祸首 。

Answer 3

仅作记录，您可以在Eclipse中定义Exception断点。 您只需要单击“添加Java异常断点”。 参见下面的图像。 请注意，使用异常断点（或使用条件断点）会对性能产生很大影响。
