1、同样导入相关的jar包
2、配置web.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>springmvc_annotation</display-name>
<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:mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
3、配置spring MVC文件
因为要使用注解的方式，所以不用配置HandlerMapping和HandlerAdapter以及接受请求的相关处理器。
只需配置需要渲染的视图以及需要主动扫描的包
<?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"
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">
<!-- 配置HandlerMapping -->
<!-- <bean
class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" /> -->
<!-- 配置HandlerAdapter -->
<!-- <bean
class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter" /> -->
<!-- 配置渲染器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<!-- 返回的结果是的前缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<!-- 返回的结果视图的后缀 -->
<property name="suffix" value=".jsp" />
</bean>
<!-- 自动扫描和配置请求处理器 -->
<context:component-scan base-package="winney.controller"></context:component-scan>
</beans>
4、编写请求处理器
package winney.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HelloController {
@RequestMapping("/hello")
public ModelAndView hello(HttpServletRequest request, HttpServletResponse response) {
ModelAndView mv = new ModelAndView();
// 封装数据到要显示的视图中
mv.addObject("msg", "Hello ,Winney.I am spring MVC anotation");
// 设置视图的名称 经过xml的配置 它会自动找到/WEB-INF/jsp/hello.jsp页面
mv.setViewName("hello");
return mv;
}
}
5、编写jsp文件
jsp文件要按照spring mvc的配置文件的配置渲染视图那里的配置来放置文件。
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
${msg }
</body>
</html>
