myeclipse中创建maven工程（SpringMVC）示例

准备：

1)jdk1.7

2)myeclipse12

3)maven3.3.9

4)tomcat7.0（最好是解压缩版）

步骤：

1)打开myeclipse.新建maven project.

Next->Next->Finish

得到目录如下。

2)此时jsp显示错误。因为pom.xml没有导入相关都jar包。故先对pom.xml进行修改。

<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">

	<packaging>war</packaging>
	<version>0.0.1-SNAPSHOT</version>
	<name>mavenspringmvctest Maven Webapp</name>
	<url>http://maven.apache.org</url>
	
		<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

	<dependencies>

			<version>1.2</version>
		</dependency>

	</dependencies>
	<build>
		<finalName>mavenspringmvctest</finalName>
	</build>
</project>

3)等待一会会儿时间就显示没错了。因为导入了javaee-api.

在WEB-INF建立下列项。

忽略applicationContext.xml。去掉好了。

web.xml如下

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">

	<display-name>Archetype Created Web Application</display-name>
	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>
	<!-- 配置springmvc 入口 -->
	<servlet>
		<servlet-name>springmvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:config/spring-web.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>
	<!-- 首页 -->
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

在web.xml中配置了spring.xml的自定义路径

classpath:config/spring-web.xml位置如下图。

4)编写java

package com.winne.springmvc.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("/")
public class HelloWorldController {
	@RequestMapping(method=RequestMethod.GET)
	public String sayHello(ModelMap model){
		model.addAttribute("greeting", "Hello World from Spring 4 MVC");
		return "welcome";
	}
	@RequestMapping(value = "/helloagain", method = RequestMethod.GET)
	public String sayHelloAgain(ModelMap model) {
		model.addAttribute("greeting", "Hello World Again, from Spring 4 MVC");
		return "welcome";
	}

}

5)右键点击project，选run，点击maven clean，maven install，Myeclipse Server Application

6)最终的目录如下。

另外几点说明：
