<!-- 加载Spring容器配置 -->

<listener>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<!-- 设置Spring容器加载配置文件路径 -->

<context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath*:applicationContext-*.xml</param-value>

</context-param>

<!-- 配置Spring核心控制器 -->

<servlet>

    <servlet-name>dispatcher</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>/WEB-INF/dispatcher.xml</param-value>

    </init-param>

    <load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

    <servlet-name>dispatcher</servlet-name>

    <url-pattern>*.do</url-pattern>

</servlet-mapping>

<!-- 解决工程编码过滤器 -->

<filter>

    <filter-name>characterEncodingFilter</filter-name>

    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

    <init-param>

        <param-name>encoding</param-name>

        <param-value>UTF-8</param-value>

    </init-param>

</filter>

<filter-mapping>

    <filter-name>characterEncodingFilter</filter-name>

    <url-pattern>/*</url-pattern>

</filter-mapping>

3、在WEB-INF目录中添加dispatcher.xml，内容如下：

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

<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"

    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"

    <!-- 注解探测器 -->

    <context:component-scan base-package="com.hoo"/>

    <!--  annotation默认的方法映射适配器 -->

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

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

</beans>
