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!,
