spring-mvc 3.* 多视图解析配置实例 ContentNegotiatingViewResolver

一、起因 
    从spring 3.1.0升级到spring 3.2.0时，配置文件servlet.xml中出错。 

错误信息： 

Java代码  收藏代码
  1. java.lang.String cannot be cast to org.springframework.http.MediaType  



错误原因：是spring3.2开始不推荐使用setMediaTypes等直接设置这些数据， 而是通过ContentNegotiationManager（ContentNegotiationManagerFactoryBean），所以采用map标签的方式直接转换会出现异常信息。 

二、ContentNegotiatingViewResolver 解释
