1、開啟myeclipse
2、新建工程:點選右鍵----New----Web Project ,新建一個名為springMvc工程,引入jar包,bulid path.
3、編寫web.xml檔案
4、新建spring-base.xml檔案,根據web.xml檔案中路徑新建spring-base.xml檔案,在src資料夾下新建spring的package,在該包下新建一個spring-base.xml檔案,檔案中內容為:<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <!--新建的檔案 --> <param-value>classpath:spring/spring-base.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>charsetEncoding</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>charsetEncoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> </web-app>
5、新建檔案dispatcherServlet-servlet.xml,在WebRoot資料夾下新建dispatcherServlet-servlet.xml檔案,內容如下:<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> </beans>
6、接下來新建controller,在src下新建 com.mycontroller的package,在該包下新建MyController.java檔案,內容:<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <mvc:annotation-driven/> <context:annotation-config/> <context:component-scan base-package="com.mycontroller"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver"> <!-- 字首 jsp檔案所在是路徑--> <property name="prefix" value="/WEB-INF/view/" /> <!-- 字尾 --> <property name="suffix" value=".jsp" /> </bean> </beans>
package com.mycontroller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/helloworld")
public class Mycontroller {
@RequestMapping("/hello")
//即使是隻有一個方法,也要寫requestMapping註解
public String hello(){
System.out.println("hello world");
return "/helloworld";
}
}
7、新建jsp頁面,根據dispatcherServlet-servlet.xml檔案中的路徑,在WEB-INF資料夾下新建view資料夾,在view資料夾中新建helloworld.jsp檔案,內容:
<%@ page language="java" contentType="text/html; charset=UTF8"
pageEncoding="UTF8"%>
<!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=UTF8">
<title>Insert title here</title>
</head>
<body>
hello world,gogogo!
</body>
</html>
8、啟動Tomcat,瀏覽器訪問http://localhost:8080/springMvc/helloworld/hello.action
