版本說明
Eclipse:Eclipse Java EE IDE for Web Developers
Version:Luna Release(4.4.0)
Tomcat:apache-tomcat-7.0.56
SpringMVC:3.2.3.RELEASE
檔案結構
SpringMVC所需JAR
步驟
1、建立web專案
運用eclipse建立Dynamic Web Project.具體過程略。
2、修改web.xml檔案
<?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</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- Spring MVC --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 自定義servlet.xml配置檔案的位置和名稱，預設WEB-INF目錄下，名稱為[<servlet-name>]-servlet.xml --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/config/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>
攔截所有請求中含有‘/’的url，類似SpringMVC/**/* 這類的url
3、建立springMVC-servlet.xml檔案
<?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" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd "> <!-- 預設掃描的包路徑 --> <context:component-scan base-package="*" /> <!-- 添加註解驅動 --> <mvc:annotation-driven /> <!-- 定義跳轉的檔案的前後綴 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/" /> <property name="suffix" value=".jsp" /> </bean> </beans>將controller中返回的String字串加上字首與字尾，並去專案中找到相應的位置
4、建立controller
package net.csdn.blog.springmvc.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class PageController { @RequestMapping("/login") public String login(Model model) { model.addAttribute("msg", "controller --> login"); return "login"; } }將鍵值放入model中，在前臺可以直接用el、jstl表示式取出
5、建立login.jsp
<%@ 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>登入介面</title> </head> <body> <h3>${msg}</h3> </body> </html>6、驗證結果
