1. 配置pom文件依賴庫版本房交，及spring依賴管理 （Maven自動來管理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 : 材料清單

   • Spring為了解決jar包沖突产徊，推出spring-framework-bom持际、spring-boot-dependencies焊唬、platform-bom用來統(tǒng)一管理Spring版本蒋纬。

2. 導(dǎo)入 Spring MVC 及其依賴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>
   

3. 配置web.xml 加入Spring核心類 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 對應(yīng)的上下文配置,默認為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>
            <!--默認攔截所有請求-->
            <url-pattern>/</url-pattern>
        </servlet-mapping>
    </web-app>
   

   • init-param

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

     配置時配置contextConfigLocation參數(shù) value = url

   • web-app

     2.3及之前版本默認關(guān)閉el表達式

     2.4版本默認開啟el表達式

4. 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/>
        
        <!--配置只關(guān)注@Contraller標注的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 默認啟用DefaultAnnotationHandlerMapping-->
    
        <!--擴充了注解驅(qū)動-->
        <mvc:annotation-driven/>
        
        <!--引入靜態(tài)資源-->
        <mvc:resources mapping="/resources/*" location="/resources/"/>
            
        <!--配置ViewResolver
            可以配置多個ViewResolver,
            使用order屬性排序,
            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來管理Service層和dao層铺呵，實現(xiàn)ApplicationContext層次化

5. 在 web.xml中加入Spring應(yīng)用的上下文

    <!--Spring 應(yīng)用上下文 層次化 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>
   

6. 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/>
        
        <!--配置關(guān)注除@Contraller標注之外的Bean-->
        <context:component-scan base-package="com.bjchaney.springmvc">
            <context:exclude-filter type="annotation" 
                expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>
     </beans>
   

7. 添加常用 ViewResolver

    <!--文件上傳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
        提供相同內(nèi)容不同表現(xiàn)形式的viewResolver
        此處用來返回Json數(shù)據(jù)
    -->
    <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>
   

8. 編寫Controller進行 相應(yīng)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";
        }
    }
