第一步：匯入包 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：配置檔案springmvc-servlet.xml配置

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       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/mvc
           http://www.springframework.org/schema/mvc/spring-mvc.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context.xsd">

    <!--配置處理器對映 HandlerMapping.使用了註解就可以不用這個了，因為不用註解這裡需要配置多個,controller類也不用繼承AbstractController介面了-->
    <!--<bean name="/index.html" class="cn.kgc.controller.IndexController"/>-->

    <!--配置檢視解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--字首-->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <!--字尾-->
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 配置掃描註解的包 -->
    <context:component-scan base-package="cn.kgc.controller" />

    <!-- 註冊HandlerMapper、HandlerAdapter兩個對映類 -->
    <mvc:annotation-driven />

  <!-- 訪問靜態資源,mapping:將靜態資源對映到指定的路徑下；location：本地靜態資原始檔所在的目錄 -->
    <mvc:default-servlet-handler />
    <mvc:resources mapping="WEB-INF/statics/**" location="WEB-INF/statics/"/>

</beans>
 

第三步：配置web.xml檔案

<?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" >

<!--2.4版本以上可以不用加er語句，也能認到er表示式-->
<web-app>
	<!--給上下文傳引數(這個會在Action裡面用到),web服務啟動時載入的xml檔案-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
      classpath:mybatis-spring.xml
    </param-value>
  </context-param>

  <!--加入一個監聽器，在服務一啟動的時候把Spring的配置檔案的mybatis-spring.xml讀取，以後不用每執行一次方法都讀取xml檔案-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
	 <!--springMvc核心控制器的配置DispatchServlet-->
  <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>

  <!-- / 攔截所有的URL請求-->
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>
 

第四步：建立Controller(處理請求的控制器，也就是servlet) 建立Controller層 新建控制類

@Controller
@RequestMapping("/user") // "/user" 訪問URL
public class IndexController extends BasDao {

    private Logger logger=Logger.getLogger(IndexController.class);
    // "/user/hello" 訪問URL
    @RequestMapping("/hello")
    public ModelAndView index(HttpServletRequest request){
        ApplicationContext context=getApplicatIonContext(request);
        DetailService dsi=(DetailService)context.getBean("detailServiceImpl");
        int i=dsi.count();
        logger.info("呼叫：index 方法,引數:null,執行結果："+i);
        return new ModelAndView("hello"); //返回邏輯檢視名，hello.jsp頁面
  }
  
	@RequestMapping(value = "/hello1",method = RequestMethod.GET,params = "username") //value:請求URL,method:請求方式,params:請求引數
    public String welcome(@RequestParam(required = false,value = "username") String username,HttpServletRequest request){ //value:引數別名，可以省略,required:是否必須
        ApplicationContext context=getApplicatIonContext(request);
        DetailService dsi=(DetailService)context.getBean("detailServiceImpl");
        int i=dsi.count();
        logger.info("呼叫：index 方法,引數:"+username+",執行結果："+i);
        return "hello";
    }


    @RequestMapping("/index1")
    public ModelAndView index(@RequestParam(defaultValue = "10",required = false) Integer age, String username,HttpServletRequest request){ //不給@RequestParam註解，url引數可給可不給，不給賦null值。但只能是引用型別或者包裝型別
                                                                                        //defaultValue＝“10”:如果不給url引數賦值，就給賦指定值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); //把引數傳送到前段
        mav.setViewName("hello"); //用那一個頁面顯示
        logger.info("呼叫：index 方法,引數:"+username+",執行結果："+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); //給 model新增資料，直接在前斷顯示
        logger.info("呼叫：index 方法,引數:"+username+",執行結果："+i);
        return "hello";
    }
    }

第五步：建立jsp檢視 第六步：部署伺服器執行
