我設置了一個id爲「exceptionResolver」的bean，使其成爲org.springframework.web.servlet.handler.SimpleMappingExceptionResolver的一個實例。然後我定義了兩個屬性「defaultErrorView」和「exceptionMappings」。異常解析器和調度程序不轉發
據我所知，它應該捕獲我的web應用程序中拋出的任何異常，並轉發到我指定的視圖。
這沒有發生，我得到的是帶有堆棧跟蹤的標準tomcat 500錯誤頁面。我究竟做錯了什麼？此外，我使用spring 2.5.5以及我所有的控制器/ dao/etc ...都是使用spring註釋來定義的。
這是一個吐出我的堆棧跟蹤。

你在瀏覽器中得到了什麼？一個空白頁面？一個堆棧跟蹤？ – rodrigoap 2009-09-30 21:05:17
Spring 2.5.5比較麻煩。使用2.5.6，它堅如磐石。 – skaffman 2009-12-29 13:54:09
