thank u for you answer,I found the root cause which result in that exception.It's my IIS.my project is deploied on iis7.0 with integrerad pipeline mode.But during initialization of the spring IOC container,there is a action that rewriting Httpcontext.Unfortunately, In the pipe events of application such as the constructor of Global,and the Application_Start event.the httpcontext is not initialized in The IIS7.0 integrerad pipeline mode. that is the root cause which giving the exception.
