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
3:修改web.xml,增加如下配置
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
5:新增controller类
6：在/WEB-INF/jsp目录下，新建helloworld.jsp
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!,

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!,
