java异常解析程序和调度程序未转发

Question

我设置了一个id为“exceptionResolver”的bean，使其成为org的一个实例。springframework。网状物servlet。汉德勒。SimpleMappingExceptionResolver。然后我定义了两个属性，“defaultErrorView”和“exceptionMappings”

据我所知，这应该会捕获web应用程序中抛出的任何异常，并转发到我指定的视图

这并没有发生，我得到的只是带有堆栈跟踪的标准tomcat 500错误页面。我做错了什么？此外，我正在使用spring 2.5.5和我所有的控制器/dao/等等。。。使用spring注释定义

这是我堆栈中的一点痕迹

Answer 1

虽然这可能不是您具体问题的答案，但我刚刚发现，大多数在线文档和示例都提到使用

org.springframework.web.servlet.handler.SimpleMappingExceptionResolver

但如果您在portlet环境中运行，则需要使用

org.springframework.web.portlet.handler.SimpleMappingExceptionResolver

希望这能帮别人省去几个小时的挠头

Answer 2

问题似乎出在Spring版本2.5.5上。我将依赖项改为2.5.1和2.5.6。sec01（单独）和转发按预期工作

Answer 3

由于2.5.5版本中的问题，Spring异常解析器无法在tomcat中呈现异常视图。详情请参考以下机票
