Spring整合SpringMVC

1.配置web.xml

<?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"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	
	<!-- 配置 DispatcherServlet -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 配置 DispatcherServlet 的一个初始化参数: 配置 SpringMVC 配置文件的位置和名称 -->
		<!-- 
			实际上也可以不通过 contextConfigLocation 来配置 SpringMVC 的配置文件, 而使用默认的.
			默认的配置文件为: /WEB-INF/<servlet-name>-servlet.xml
		-->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	
	<!-- 配置SpringIoc容器 -->
    <listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener> 
	
	<!--contextConfigLocation在 ContextLoaderListener类中的默认值是 /WEB-INF/applicationContext.xml-->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:beans.xml</param-value>
		<!-- <param-value>classpath:applicationContext*.xml</param-value> -->
	</context-param>
	
	
</web-app>

2.配置Spring配置文件

<?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:util="http://www.springframework.org/schema/util"
	xmlns:p="http://www.springframework.org/schema/p"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
	
	<!-- 配置自定扫描的包 -->
	<context:component-scan base-package="com.wr.springmvc">
		<!-- 配置不扫描controller 和 controllerAdvise -->
		<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
		<context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
	</context:component-scan>
	
</beans>

3.配置SpringMVC配置文件

<?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.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

	<!-- 配置自定扫描的包 -->
	<context:component-scan base-package="com.wr.springmvc" use-default-filters="false">
		<!-- 配置只扫描controller 和 controllerAdvise -->
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
		<context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
	</context:component-scan>

	<!-- 配置视图解析器: 如何把 handler 方法返回值解析为实际的物理视图 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/views/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	
	<bean class="org.springframework.web.servlet.view.BeanNameViewResolver" >
		<property name="order" value="100"></property>
	</bean>
	
	<!-- 配置国际化资源文件 -->
	<bean id="messageSource"
		class="org.springframework.context.support.ResourceBundleMessageSource">
		<property name="basename" value="i18n"></property>	
	</bean>

</beans>

 注意: Spring中的bean不能引用SpringMVC容器中的bean
