配置pom文件依赖库版本，及spring依赖管理（Maven自动来管理Spring版本）

 <properties>
     <spring.version>4.1.3.RELEASE</spring.version>
     <commons.lang.version>2.6</commons.lang.version>
     <slf4j.version>1.7.6</slf4j.version>
 </properties>
 <dependencyManagement>
     <dependencies>
         <dependency>
             <groupId>org.springframework</groupId>
             <artifactId>spring-framework-bom</artifactId>
             <version>${spring.version}</version>
             <type>pom</type>
             <scope>import</scope>
         </dependency>
     </dependencies>
  </dependencyManagement>

bom : 材料清单
Spring为了解决jar包冲突，推出spring-framework-bom、spring-boot-dependencies、platform-bom用来统一管理Spring版本。

导入 Spring MVC 及其依赖jar包

 <dependency>
     <groupId>org.springframework</groupId>
     <artifactId>spring-webmvc</artifactId>
 </dependency>
 <dependency>
     <groupId>org.slf4j</groupId>
     <artifactId>slf4j-log4j12</artifactId>
     <version>${slf4j.version}</version>
     <exclusions>
         <exclusion>
             <groupId>org.slf4j</groupId>
             <artifactId>slf4j-api</artifactId>
         </exclusion>
     </exclusions>
  </dependency>
  <dependency>
        <groupId>commons-lang</groupId>
        <artifactId>commons-lang</artifactId>
        <version>${commons.lang.version}</version>
  </dependency>

配置web.xml 加入Spring核心类 DispacherServlet

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="2.4" 
     xmlns="http://java.sun.com/xml/ns/j2ee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
         http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
     
     <servlet>
         <servlet-name>mvc-dispatcher</servlet-name>
         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
         <!-- DispatcherServlet 对应的上下文配置,默认为WEB-INF/${servlet-name}-servlet.xml -->
         <init-param>
             <param-name>contextConfigLocation</param-name>
             <param-value>/WEB-INF/configs/spring/mvc-dispatcher.xml</param-value>
         </init-param>
         <load-on-startup>1</load-on-startup>
     </servlet>
 
     <servlet-mapping>
         <servlet-name>mvc-dispatcher</servlet-name>
         <!--默认拦截所有请求-->
         <url-pattern>/</url-pattern>
     </servlet-mapping>
 </web-app>

init-param

可以不去配置，省略后默为/WEB-INF/${servlet-name}-servlet.xml

配置时配置contextConfigLocation参数 value = url
web-app

2.3及之前版本默认关闭el表达式

2.4版本默认开启el表达式

添加Spring MVC 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: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.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/mvc/spring-mvc.xsd">
 
     <!--激活注解配置-->
     <context:annotation-config/>
     
     <!--配置只关注@Contraller标注的Bean-->
     <context:component-scan base-package="com.bjchaney.springmvc">
         <context:include-filter type="annotation" 
             expression="org.springframework.stereotype.Controller"/>
     </context:component-scan>
     
     <!--HandlerMapping 不需要配置 SpringMVC 默认启用DefaultAnnotationHandlerMapping-->
 
     <!--扩充了注解驱动-->
     <mvc:annotation-driven/>
     
     <!--引入静态资源-->
     <mvc:resources mapping="/resources/*" location="/resources/"/>
         
     <!--配置ViewResolver
         可以配置多个ViewResolver,
         使用order属性排序,
         InternalResourceViewResolver 放在最后
         -->
     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <!--配置使用支持jstl的view-->
         <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
         <property name="prefix" value="/WEB-INF/jsp/"/>
         <property name="suffix" value=".jsp"/>
     </bean>
 </beans>

Spring-MVC 所有的配置完成
之后加入Spring来管理Service层和dao层，实现ApplicationContext层次化

在 web.xml中加入Spring应用的上下文

 <!--Spring 应用上下文 层次化 applicationContext-->
 <context-param>
     <param-name>contextConfigLocation</param-name>
     <param-value>/WEB-INF/configs/spring/applicationContext*.xml</param-value>
 </context-param>
 
 <listener>
     <listener-class>
         org.springframework.web.context.ContextLoaderListener
     </listener-class>
 </listener>

添加Spring容器的配置文件

 <?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: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.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/mvc/spring-mvc.xsd">
 
     <!--激活注解配置-->
     <context:annotation-config/>
     
     <!--配置关注除@Contraller标注之外的Bean-->
     <context:component-scan base-package="com.bjchaney.springmvc">
         <context:exclude-filter type="annotation" 
             expression="org.springframework.stereotype.Controller"/>
     </context:component-scan>
  </beans>

添加常用 ViewResolver

 <!--文件上传viewResolver-->
 <bean id="multipartResolver" 
     class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
     <property name="maxUploadSize" value="2000000"/>
     <property name="defaultEncoding" value="UTF-8"/>
     <property name="resolveLazily" value="true"/>
 </bean>

 <!--  ContentNegotiatingViewResolver
     提供相同内容不同表现形式的viewResolver
     此处用来返回Json数据
 -->
 <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
     <property name="order" value="1"/>
     <property name="mediaTypes">
         <map>
             <entry key="json" value="application/json"/>
             <entry key="xml" value="application/xml"/>
             <entry key="html" value="text/html"/>
         </map>
     </property>
     <property name="defaultViews">
         <list>
             <bean 
             class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">
             </bean>
         </list>
     </property>
     <property name="ignoreAcceptHeader" value="true"/>
 </bean>

编写Controller进行相应操作Example

 @Controller
 @RequestMapping("/hello")
 public class HelloController {
     
     @Autowired
     UserService userService;
     
     @RequestMapping(value = "/impl1",method = RequestMethod.GET)
     public String hello(String name,Model model){
         model.addAttribute("name", userService.getFotmatName(name));
         return "hello";
     }
     
     @RequestMapping(value = "/impl2",method = RequestMethod.GET)
     public String hello(String name,Map<String,String> model){
         model.put("name", userService.getFotmatName(name));
         return "hello";
     }
     
     @RequestMapping(value = "/impl3",method = RequestMethod.GET)
     public String hello(HttpServletRequest request){
         String name = request.getParameter("name");
         request.setAttribute("name", userService.getFotmatName(name));
         return "hello";
     }
 
     @RequestMapping(value = "/json",method = RequestMethod.GET)
     @ResponseBody
     public RestResponse<String> hello(@ModelAttribute("name") String name){
         RestResponse restResponse = new RestResponse();
         return restResponse.success(name);
     }
     
     @RequestMapping(value = "/upload",method = RequestMethod.GET)
     public String hello(){
         return "upload";
     }
     @RequestMapping(value = "/doUpload",method = RequestMethod.POST)
     public String doUpload(MultipartFile file) throws Exception{
         if(!file.isEmpty()){
             userService.CopyFile(file.getInputStream(), "~/Documents/1.jpg");
         }
         return "success";
     }
 }
