Question

我的配置与spring-petclinic应用程序非常相似，似乎SimpleMappingExceptionResolver正常工作并解析为视图＆＃34;错误＆＃34;，但与ContentNegotiatingViewResolver无法很好地解决该观点：

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)
...

这是DEBUG日志：

这里是视图解析器配置：

<!-- - 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="mediaTypes">

            <entry key="xml" value="application/xml" />
            <entry key="atom" value="application/atom+xml" />
        </map>
    </property>
</bean>

Answer 1

从您的评论中可以看出，您对Spring Error Handling感兴趣。请阅读very descriptive documentation on the subject（SimpleMappingExceptionResolver部分）：您所要做的就是使用默认错误视图注册SimpleMappingExceptionResolver：

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

</bean>

Spring MVC SimpleMappingExceptionResolver在使用ContentNegotiatingViewResolver时不解析视图
