严重: Servlet.service() for servlet [springmvc] in context with path [/blog] threw exception [Circular view path [showArticleType]: would dispatch back to the current handler URL [/blog/showArticleType] again. Check your ViewResolver
setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)] with root cause

在开发时尽量不要自己注册如：

Java代码  


<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>  

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">  

尽量使用

Java代码  


<mvc:annotation-driven/>   

它设计的已经足够好，使用子元素可以配置我们需要的配置。

  

且不要使用老版本的：

Java代码  


<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>  

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">  

否则可能得到如下异常：
