**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_3_0.xsd" version="3.0">
        <display-name>SpringMVC</display-name>

        </welcome-file-list>
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-aop.xml</param-value>
        </context-param>
        <servlet>
            <servlet-name>SpringMVC</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>classpath:spring-mvc.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>

        <servlet-mapping>

            <url-pattern>*.html</url-pattern>
        </servlet-mapping>
    </web-app>

在web.xml文件中若无context-param元素指明contextConfigLocation的value值，spring将会默认查找位于WEB-INFO下的applicationContext.xml，若无此文件则将抛出异常：  
IOException parsing XML document from ServletContext resource \[/WEB-INF/applicationContext.xml\]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource \[/WEB-INF/applicationContext.xml\]

**spring-mvc.xml**

<?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:p="http://www.springframework.org/schema/p" 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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
    
        
        <context:component-scan base-package="com.peanut.spring"/>
    
        <mvc:annotation-driven content-negotiation-manager="contentNegotiationManager"/>
    
        
        <mvc:default-servlet-handler/>
    
        
        <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/views/" p:suffix=".html"/>
    
        <bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
            <property name="favorPathExtension" value="false"/>
            <property name="favorParameter" value="false"/>
            <property name="ignoreAcceptHeader" value="false"/>
            <property name="mediaTypes">
                <value>
                    atom=application/atom+xml
                    html=text/html
                    json=application/json
                    *=*/*
                </value>
            </property>
        </bean>
    
    </beans>

然后在controller层可使用注解方式调用

/** * Created by peanut on 2016/4/21. */
    @Controller
    @RequestMapping("/springmvc")
    public class HomeController { 
    
        @RequestMapping("home.html")
        public String home(){
            System.out.println("This is home controller！");
            return "home";
        }
    }
