第一步：导入包  
aopalliance-1.0.jar  
aspectjweaver-1.8.13.jar  
commons-logging-1.2.jar  
javax.servlet-api-3.1.0.jar  
jstl-1.2.jar  
spring-aop-3.2.13.RELEASE.jar  
spring-beans-3.2.13.RELEASE.jar  
spring-context-3.2.13.RELEASE.jar  
spring-core-3.2.13.RELEASE.jar  
spring-expression-3.2.13.RELEASE.jar  
spring-web-3.2.13.RELEASE.jar  
spring-webmvc-3.2.13.RELEASE.jar

第二步：配置文件springmvc-servlet.xml配置

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

           xmlns:mvc="http://www.springframework.org/schema/mvc"

        <bean id="myConversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">

    </beans>

第三步：配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE web-app PUBLIC
     "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
     "http://java.sun.com/dtd/web-app_2_3.dtd" >
    
    
    <web-app>
    	
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
          classpath:mybatis-spring.xml
        </param-value>
      </context-param>
    
      
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      
    	 
      <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:springmvc-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
      </servlet>
    
      
      <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
    
    </web-app>

第四步：创建Controller(处理请求的控制器，也就是servlet)  
创建Controller层  
新建控制类

@Controller
    @RequestMapping("/user") // "/user" 访问URL
    public class IndexController extends BasDao {
    
        private Logger logger=Logger.getLogger(IndexController.class);
        // "/user/hello" 访问URL
        @RequestMapping("/hello")
        public ModelAndView index(HttpServletRequest request){
            ApplicationContext context=getApplicatIonContext(request);
            DetailService dsi=(DetailService)context.getBean("detailServiceImpl");
            int i=dsi.count();
            logger.info("调用：index 方法,参数:null,执行结果："+i);
            return new ModelAndView("hello"); //返回逻辑视图名，hello.jsp页面
      }
      
    	@RequestMapping(value = "/hello1",method = RequestMethod.GET,params = "username") //value:请求URL,method:请求方式,params:请求参数
        public String welcome(@RequestParam(required = false,value = "username") String username,HttpServletRequest request){ //value:参数别名，可以省略,required:是否必须
            ApplicationContext context=getApplicatIonContext(request);
            DetailService dsi=(DetailService)context.getBean("detailServiceImpl");
            int i=dsi.count();
            logger.info("调用：index 方法,参数:"+username+",执行结果："+i);
            return "hello";			//转发
            //return "redirect:/user/hello"; 	//重定向
        }
    
    
        @RequestMapping("/index1")
        public ModelAndView index(@RequestParam(defaultValue = "10",required = false) Integer age, String username,HttpServletRequest request){ //不给@RequestParam注解，url参数可给可不给，不给赋null值。但只能是引用类型或者包装类型
                                                                                            //defaultValue＝“10”:如果不给url参数赋值，就给赋指定值10，
            ApplicationContext context=new ClassPathXmlApplicationContext("mybatis-spring.xml");
            DetailService dsi=(DetailService)context.getBean("detailServiceImpl");
            int i=dsi.count();
            ModelAndView mav=new ModelAndView();
            mav.addObject("username",username+age); //把参数传送到前段
            mav.setViewName("hello"); //用那一个页面显示
            logger.info("调用：index 方法,参数:"+username+",执行结果："+i);
            return mav;
        }
    
    
        @RequestMapping("/index2")
        public String index2(String username, Model model){
            ApplicationContext context=new ClassPathXmlApplicationContext("mybatis-spring.xml");
            DetailService dsi=(DetailService)context.getBean("detailServiceImpl");
            int i=dsi.count();
            model.addAttribute("username",username); //给 model添加数据，直接在前断显示
            logger.info("调用：index 方法,参数:"+username+",执行结果："+i);
            return "hello";
        }
        }

第五步：创建jsp视图

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
    <%@ taglib prefix="fm" uri="http://www.springframework.org/tags/form" %>
    <%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
    <%@page isELIgnored="false"%>
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    
    <html>
    <head>
        <title>Title</title>
        <link rel="stylesheet" type="text/css" href="/chun/statics/css/comm.css"/>
    
    </head>
    <body>
        <h1>${username}123456</h1>
        语言选择:
        <a href="?lang=zh_CN"><spring:message code="language.cn"/></a>    
        <a href="?lang=en_US"><spring:message code="language.us"/></a>
        <h1><spring:message code="zsc"/></h1>
        <h2><fmt:message key="zsc"/></h2>
        <h3>${msg}</h3>
        当前语言: ${pageContext.response.locale }
        <img src="/chun/statics/images/ccc.jpg">
        <c:out value="value" default="1" escapeXml="true"/>
        <c:forEach var="名称" items="集合对象" varStatus="index索引号">
    
        </c:forEach>
    <c:if test="条件" var="varName" scope="request">
    
    </c:if>
    <fmt:formatDate value="date" pattern="yyyy-MM-dd"/>
    </body>
    </html>

第六步：部署服务器运行
