Spring MVC 学习笔记一创建项目

1：新建maven 工程
运行以下maven命令，建立一个jee5的web工程。

mvn archetype:generate -DinteractiveMode=false -DarchetypeGroupId=org.codehaus.mojo.archetypes -DarchetypeArtifactId=webapp-jee5 -Dversion=0.0.1-SNAPSHOT -DgroupId=net.zhepu -DartifactId=springmvc

2:修改pom.xml，增加spring mvc 3.0.5的依赖包及jetty plugin

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<org.springframework.version>3.0.5.RELEASE</org.springframework.version>
	</properties>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-webmvc</artifactId>
			<version>${org.springframework.version}</version>
		</dependency>

			<plugin>
				<groupId>org.mortbay.jetty</groupId>
				<artifactId>jetty-maven-plugin</artifactId>
				<version>7.4.0.v20110414</version>
				<configuration>
					<scanIntervalSeconds>10</scanIntervalSeconds>
					<webAppConfig>
						<contextPath>/springmvc</contextPath>
						<defaultsDescriptor>src/main/resources/webdefault.xml</defaultsDescriptor>
					</webAppConfig>
				</configuration>
			</plugin>

3:修改web.xml,增加如下配置


	<servlet>
		<servlet-name>mvcServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath*:/spring/web/servlet-context.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>mvcServlet</servlet-name>
		<url-pattern>*.action</url-pattern>
	</servlet-mapping>

Spring-mvc缺省是在WEB-INF目录下找名称未${servlet-name}-context.xml的配置文件，这里通过contextconfiglocation的配置，将spring-mvc所需的配置文件指向到src\resources\spring\web目录下。

4:在src\resources\spring\web下，新建 servlet-context.xml，内容如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc" 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-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.xsd
">
	<context:component-scan base-package="net.zhepu.web" />
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.UrlBasedViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" />
	</bean>

</beans>

5:新增controller类

package net.zhepu.web;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/helloworld")
public class Helloworld {

	@RequestMapping(method=RequestMethod.GET)
	public ModelAndView hello() {
		ModelAndView mv = new ModelAndView();
		mv.setViewName("helloworld");
		return mv;
	}
}

6：在/WEB-INF/jsp目录下，新建helloworld.jsp

<%@page contentType="text/html" 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>JSP Page</title>
    </head>
    <body>
        <h1>Hello World!</h1>
    </body>
</html>

7：运行mvn jetty:run 启动工程后，访问http://localhost:8080/springmvc/helloworld.action ,可以看到Hello World!,
