SpringMVC 配置文件详解

1. 配置web.xml. 启动SpringMVC

SpringMVC 是通过Servlet启动，所以需要在web.xml中配置SpringMVC的Servlet。如下代码示例：

<span style="white-space:pre">	</span><servlet>
		<servlet-name>springServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/applicationContext-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>springServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

2. applicationContext-mvc.xml（该文件名称可以自定义，但是要和web.xml中名称保持一致）

<?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-4.0.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">
    
    <description>Spring MVC Configuration</description>
    
    <!-- 加载Properties文件 -->
	<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<list>
				<value>classpath:config.properties</value>
			</list>
		</property>
	</bean>
    
    <!-- 使用Annotation自动注册Bean,只扫描@Controller -->
	<context:component-scan base-package="cn.tyrone.wallet.controller" use-default-filters="false">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>
    
    <!-- 定义视图文件解析 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="${web.view.prefix}"/>
		<property name="suffix" value="${web.view.suffix}"/>
	</bean>
	
	<mvc:annotation-driven />
	
	<!-- 静态资源映射 -->
    <span style="white-space:pre">	</span><mvc:resources mapping="/static/**" location="/static/" cache-period="31536000"/>
	
	<!-- 定义无Controller的path<->view直接映射 -->
	<mvc:view-controller path="/" view-name="redirect:${web.view.index}"/>
    
</beans>
