[The prefix "mvc" for

在springmvc配置文件里面写默认的注解映射的支持的时候：<mvc:annotation-driven />The prefix "mvc" for element "mvc:annotation-driven" is not bound。
解决办法：
在该配置文件上面的beans中添加
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"

例：添加之前的代码:
<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.xsd"
default-lazy-init="true">

添加之后的代码：

<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/mvc**

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

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

   default-lazy-init="true">
