Question

当我在Eclipse中调试Spring应用程序时，我得到了很长的异常链。例如，我有

Error creating bean with name '...' defined in file [...Tester.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property '...' threw exception; nested exception is java.lang.IllegalArgumentException: ...

等等。 Spring中有多个异常堆栈，这是无趣的。它应该是我在下面某处的例外情况，但Spring并未显示它们。

我无法像往常一样点击异常并导航到问题所在地。

如何说Spring输出所有异常？

更新

以下是完整输出。可以看到IllegalArgumentException发生的地方可能已被截断。

因为可能存在多个异常，所以需要捕获PropertyBatchUpdateException并调用getPropertyAccessExceptions()来检查特定异常的堆栈跟踪。

修改

其实我不太确定这里发生了什么

以下是PropertyBatchUpdateException的{{1}}方法：

printStackTrace

它应该包括嵌套的堆栈跟踪。您使用的是最新版本的Spring吗？

编辑：

我能建议的最好的方法是在调试模式下运行，然后在public void printStackTrace(PrintWriter pw) { synchronized (pw) { pw.println(getClass().getName() + "; nested PropertyAccessException details (" + getExceptionCount() + ") are:"); for (int i = 0; i < this.propertyAccessExceptions.length; i++) { pw.println("PropertyAccessException " + (i + 1) + ":"); this.propertyAccessExceptions[i].printStackTrace(pw); } } }放置一个断点，看看发生了什么。

如何查看由Spring隐藏的嵌套异常跟踪？
