在pom.xml中配置spring及springmvc，
我採用的版本為3.0.5.RELEASE
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.test.spring</groupId>
<artifactId>springMVC</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>springMVC Maven Webapp</name>
<url>http://maven.apache.org</url>
<properties>
<spring.version>3.0.5.RELEASE</spring.version>
</properties>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
<!-- Spring 3 dependencies -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
</dependencies>
<build>
<finalName>springMVC</finalName>
</build>
</project>
接下來配置web.xml
<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Created Web Application</display-name> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/davis-dispatcher-servlet.xml</param-value> </context-param> <servlet> <servlet-name>davis-dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>davis-dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
其中有幾個項目要注意一下：
contextConfigLocation：這是要載入的spring配置文件
DispatcherServlet：springmvc的核心，就好比一個servlet一樣，負責接收請求及協調各組件的工作
servlet-mapping：在什麼樣的結尾需要被DispatcherServlet攔截
listener：springmvc的啟動類，負責springIoC容器的初始化
設定完成之後，接下來是 davis-dispatcher-servlet.xml的配置
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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">
<context:component-scan base-package="com.davis.controller" />
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>
幾個要注意的特別項目：
context:component-scan：會去掃描該package底下的所有control類別
prefix：返回response時去找的頁面路徑
suffix：返回頁面的檔案類型
最後就是control類別的部分：
package com.davis.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/hello")
public class HelloController {
@RequestMapping(method = RequestMethod.GET)
public String hello(ModelMap map) {
map.put("message", "Hello ~ spring MVC");
return "hello/welcome";
}
}
以及跳轉完成的頁面：
<%@ 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=BIG5">
<title>Insert title here</title>
</head>
<body>
<h1>Message : ${message}</h1>
</body>
</html>
最後啟動tomcat，即可看到歡迎畫面
