Xml 前缀为；xmnls"；对于属性“；xmnls:mvc"；与元素类型“关联”；豆子“；不受约束

错误*与元素类型“bean”关联的属性“xmnls:mvc”的前缀“xmnls”未绑定。 请帮帮我…先谢谢你。*

This is my Spring-Dispatcher-Servlet.xml

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

           <context:component-scan base-package="com.gontu.Annotation.Helloexample"></context:component-scan>
           <mvc:annotation-driven/>

           <bean id = "viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
           <property name="prefix">
            <value>/WEB-INF/</value>
           </property>
              <property name="suffix">
            <value>.jsp</value>
           </property>
           </bean>
           </beans>

这是我的Spring-Dispatcher-Servlet.xml
/WEB-INF/
.jsp

更改

       xmnls:mvc="http://www.springframework.org/schema/mvc"
         ^^

到

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