1.配置IOC容器

    <!-- 配置IOC容器 -->

    <context-param>

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

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

    </context-param>

    <listener>

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

    </listener>

<!-- Spring MVC配置 -->

<!-- ====================================== -->

<servlet>

    <servlet-name>spring</servlet-name>

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

    <!-- 可以自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml

    <init-param>

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

        <param-value>/WEB-INF/spring-servlet.xml</param-value>  默认

    </init-param>

    -->

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

</servlet>

<servlet-mapping>

    <servlet-name>spring</servlet-name>

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

</servlet-mapping>

    <!--解决字符集编码问题-->

    <filter>

        <filter-name>encodingFilter</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>encodingFilter</filter-name>

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

    </filter-mapping>

    <!-- 实现rest风格 -->

    <filter>

        <filter-name>HiddenHttpMethodFilter</filter-name>

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

    </filter>

    <filter-mapping>

        <filter-name>HiddenHttpMethodFilter</filter-name>

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

    </filter-mapping>

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

<beans xmlns="http://www.springframework.org/schema/beans" //这表示默认命名空间

    xmlns:hdp="http://www.springframework.org/schema/hadoop"

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

</beans>

在context:component-scan可以添加use-default-filters

spring配置中的use-default-filters用来指示是否自动扫描带有

@Component、@Repository、@Service和@Controller的类。默认为true，即默认扫描。

    <context:component-scan base-package="com.nn.web.controller"

            use-default-filters="false">

            <context:include-filter type="annotation"

                expression="org.springframework.stereotype.Controller" />

        </context:component-scan>

spring+springmvc+hibernate配置文件如下

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

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns="http://java.sun.com/xml/ns/javaee"

    id="WebApp_ID" version="2.5">

    <welcome-file-list>

        <welcome-file>index.html</welcome-file>

        <welcome-file>index.htm</welcome-file>

        <welcome-file>index.jsp</welcome-file>

        <welcome-file>default.html</welcome-file>

        <welcome-file>default.htm</welcome-file>

        <welcome-file>default.jsp</welcome-file>

    </welcome-file-list>

    <!-- 配置IOC容器 -->

    <context-param>

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

    </context-param>

    <listener>

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

    </listener>

    <!-- 配置springmvc DispatcherServlet -->

    <servlet>

        <servlet-name>springDispatcherServlet</servlet-name>

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

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

    </servlet>

    <servlet-mapping>

        <servlet-name>springDispatcherServlet</servlet-name>

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