基于配置文件xml方式，

配置springmvc步骤：

1.在pom文件中引入jar包：

 <!--导入springmvc的jar包-->

  <dependency>

      <groupId>org.springframework</groupId>

      <artifactId>spring-webmvc</artifactId>

    <version>4.3.1.RELEASE</version>

  </dependency>

2. 在web.xml文件中添加servlet

 <servlet>

    <servlet-name>SpringMVC</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <!--配置springmvc.xml的路径-->

    <init-param>

      <param-name>contextConfigLocation</param-name>

      <param-value>classpath:springmvc.xml</param-value>

    </init-param>

  </servlet>

  <servlet-mapping>

    <servlet-name>SpringMVC</servlet-name>

    <url-pattern>/</url-pattern>

  </servlet-mapping>

3. 创建Handler接口实现类，

		import org.springframework.web.servlet.ModelAndView;

	import org.springframework.web.servlet.mvc.Controller;

	/**

	 * Created by Intellij IDEA.

	 * User:  陈亚萌

	 * Date:  2019/9/3

	 */

	public class MyHandler implements Controller {

	    @Override

	    public ModelAndView handleRequest(javax.servlet.http.HttpServletRequest httpServletRequest, javax.servlet.http.HttpServletResponse httpServletResponse) throws Exception {

	        //装在模型数据和逻辑视图

	        ModelAndView modelAndView=new ModelAndView();

	        //添加模型数据

	        modelAndView.addObject("name","tom");

	        //添加逻辑视图

	        modelAndView.setViewName("show");

	        return modelAndView;

	    }

	}

3. 在resources中创建springmvc.xml文件，关联起来

			<?xml version="1.0" encoding="UTF-8"?>

	<beans xmlns="http://www.springframework.org/schema/beans"

	       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

	    <!--配置HandlerMapping，将url请求映射到Handler-->

	    <bean id="handlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

	        <!--配置mapping-->

	        <property name="mappings">

	            <props>

	                <!--配置test请求对应的handler-->

	                <prop key="/test">testHandler</prop>

	            </props>

	        </property>

	    </bean>

	    <!--配置-->

	    <bean id="testHandler" class="MyHandler"></bean>

	    <!--配置视图解析器-->

	    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

	        <!--配置前缀-->

	        <property name="prefix" value="/"></property>

	        <!--配置后缀-->

	        <property name="suffix" value=".jsp"></property>

	    </bean>

	</beans>

springmvc中的配置

 <?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"

        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">

 <!--将annotationHandler自动扫描到ioc容器-->

     <context:component-scan base-package="com.imooc.handler"></context:component-scan>

     <!--配置视图解析器-->

     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

         <!--配置前缀-->

         <property name="prefix" value="/"></property>

         <!--配置后缀-->

         <property name="suffix" value=".jsp"></property>

     </bean>

 </beans>

创建controller，并加注解

 	package com.imooc.handler;

 	import org.springframework.stereotype.Controller;

 	import org.springframework.ui.Model;

 	import org.springframework.web.bind.annotation.RequestMapping;

 	import org.springframework.web.servlet.ModelAndView;

 	import javax.jws.WebParam;

 	import java.util.Map;

 	/**

 	 * Created by Intellij IDEA.

 	 * User:  陈亚萌

 	 * Date:  2019/9/3

 	 */

 	@Controller

 	public class AnnotationHandler {

 	    /**

 	     * 业务方法：ModelAndView完成数据的传递和视图的解析

 	     */

 	    @RequestMapping("/model")

 	    public ModelAndView modelAndViewTest(){

 	        //创建ModelAndView对象

 	        ModelAndView modelAndView=new ModelAndView();

 	        //填充数据

 	        modelAndView.addObject("name","cym");

 	        //设置逻辑视图

 	        modelAndView.setViewName("show");

 	        return modelAndView;

 	    }

 	    /*

 	    * 业务方法：使用Model传值，String进行视图解析

 	    * */

 	    @RequestMapping("modelAndTest")

 	    public String modelTest(Model model){

 	        //填充模型数据

 	        model.addAttribute("name","yyh");

 	        //设置逻辑视图

 	        return "show";

 	    }

 	    /*

 	    * 业务方法：Map传值：String，进行视图解析

 	    * */

 	    @RequestMapping("map")

 	    public String MapTest(Map<String,String> map){

 	        //设置模型数据

 	        map.put("name","cymhhh");

 	        //设置逻辑视图

 	        return "show";

 	    }

 	}

	 <!--处理中文乱码-->

	  <filter>

	    <filter-name>encodingFilter</filter-name>

	    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

	    <init-param>

	      <param-name>encoding</param-name>

	      <param-value>UTF-8</param-value>

	    </init-param>

	    <init-param>

	      <param-name>forceEncoding</param-name>

	      <param-value>true</param-value>

	    </init-param>

	  </filter>

	  <filter-mapping>

	    <filter-name>encodingFilter</filter-name>

	    <url-pattern>/*</url-pattern>

	  </filter-mapping>

	  <!--设置访问静态资源-->

	  <servlet-mapping>

	    <servlet-name>default</servlet-name>

	    <url-pattern>*.css</url-pattern>

	  </servlet-mapping>

记得在配置的时候什么地方加/*,什么地方不加 *

	<filter-mapping>

	    <filter-name>encodingFilter</filter-name>

	    <url-pattern>/*</url-pattern>

	  </filter-mapping>
