spring 3.2 MVC 406 Not Acceptable 解决方法

 最近用spring3.2 +extjs4 返回json数据的时候，在浏览器中出现了 406 Not Acceptable 的错误，百度了下 406错误是因为MIME 类型不匹配，解决方法：

 <?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

xmlns:mvc="http://www.springframework.org/schema/mvc"

 

    xsi:schemaLocation="http://www.springframework.org/schema/beans

         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

         http://www.springframework.org/schema/context

         http://www.springframework.org/schema/tx

         http://www.springframework.org/schema/mvc  

         http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

把 spring-mvc-3.0.xsd 更新到 spring-mvc-3.2.xsd 即 

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="http://www.springframework.org/schema/beans

         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

         http://www.springframework.org/schema/context

         http://www.springframework.org/schema/context/spring-context-3.0.xsd

        http://www.springframework.org/schema/mvc 

        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

然后把 <mvc:annotation-driven />

更改成：

<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"> 
    <property name="favorPathExtension" value="false" /> 
    <property name="favorParameter" value="false" /> 
    <property name="ignoreAcceptHeader" value="false" />
    <property name="mediaTypes" > 
        <value> 
        atom=application/atom+xml 
        html=text/html 
        json=application/json
        xml=application/xml  
        *=*/* 
        </value> 
    </property> 
    </bean>
