Spring MVC SimpleMappingExceptionResolver在使用ContentNegotiatingViewResolver時未解析視圖

Question

我有一個與spring-petclinic應用程序非常相似的配置，它看起來像SimpleMappingExceptionResolver工作正常並解決了視圖「錯誤」，但不能很好地與ContentNegotiatingViewResolver解決這一觀點：

javax.servlet.ServletException: Could not resolve view with name 'error' in servlet with name 'audit' 
org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1204) 
org.springframework.web.servlet.DispatcherServlet.processDispatchResult(DispatcherServlet.java:1005) 
... 

這裏的調試日誌：

這裏的視圖解析器配置：

<!-- - The ContentNegotiatingViewResolver delegates to the InternalResourceViewResolver 
    and BeanNameViewResolver, - and uses the requested media type (determined 
    by the path extension) to pick a matching view. - When the media type is 
    'text/html', it will delegate to the InternalResourceViewResolver's JstlView, 
    - otherwise to the BeanNameViewResolver. --> 
<bean 
    class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> 
    <property name="contentNegotiationManager" ref="cnManager" /> 

    <property name="viewResolvers"> 
     <list> 
      <!-- Default viewClass: JSTL view (JSP with html output) --> 
      <bean 
       class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
       <!-- Example: a logical view name of 'vets' is mapped to '/WEB-INF/jsp/vets.jsp' --> 
       <property name="prefix" value="/WEB-INF/jsp/" /> 
       <property name="suffix" value=".jsp" /> 
      </bean> 

      <!-- Used here for 'xml' and 'atom' views --> 
      <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" /> 
     </list> 
    </property> 
</bean> 

<!-- Simple strategy: only path extension is taken into account --> 
<bean id="cnManager" 
    class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"> 
    <property name="favorPathExtension" value="true" /> 
    <property name="ignoreAcceptHeader" value="true" /> 
    <property name="defaultContentType" value="text/html" /> 

    <property name="mediaTypes">

     </map>

從您的評論顯然您對Spring Error Handling感興趣。請閱讀very descriptive documentation on the subject（SimpleMappingExceptionResolver部分）：所有你需要做的就是註冊SimpleMappingExceptionResolver用默認的錯誤觀點：

<bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> 
    <!-- other params --> 
    <property name="defaultErrorView" value="yourDefaultViewForErrors"/> 

</bean>
