Eclipse利用Maven2搭建SpringMVC框架的Web工程

一、准备工作：

　　下载apache-maven--> 配置Maven_home -->下载Eclipse Maven插件

二、新建工程：

　　   选择新建Maven Project  archetype选择webapp-->输入group ID （src下包名）和Artifact ID (工程名)

新建Maven工程目录如上图

三、补齐缺失的文件夹：

          添加Server支持和缺失的源文件夹

四、添加springMvc支持和web容器支持（若没有，打包时会报错）

<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.maven.my</groupId><artifactId>TestMaven2</artifactId><packaging>war</packaging><version>0.0.1-SNAPSHOT</version><name>TestMaven2 Maven Webapp</name><url>http://maven.apache.org</url>

<properties>
<spring.version>4.1.5.RELEASE</spring.version>
</properties>

<dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.1.0</version></dependency></dependencies><build><finalName>TestMaven2</finalName></build>
</project>

（五）修改工程配置：

 在以上两个文件中修改jdk版本为1.7以上 web为3.0

六：添加springMvc配置：

web.xml

<?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_3_0.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="study" version="3.0"><display-name>Archetype Created Web Application</display-name><description>sprintMVC环境搭建</description><!-- 加载Spring配置文件 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:configs/beans.xml</param-value></context-param><!-- Spring监听 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- Spring MVC配置 --><servlet><servlet-name>Dispatcher</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><!-- 自定义spring mvc的配置文件名称和路径 --><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:configs/beans-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><!-- spring mvc 请求后缀 --><servlet-mapping><servlet-name>Dispatcher</servlet-name><url-pattern>/</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

src/com/main/resources文件夹下的beans.xml和beans-mvc.xml

beans.xml:

<?xml version="1.0" encoding="UTF-8"?>
<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:property-placeholder /><context:annotation-config /></beans>    

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"xmlns:util="http://www.springframework.org/schema/util" xmlns:context="http://www.springframework.org/schema/context"xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/util  http://www.springframework.org/schema/util/spring-util.xsdhttp://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsdhttp://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"><context:property-placeholder /><!-- MVC控制类扫描 --><context:component-scan base-package="com.my.controller" /><mvc:annotation-driven /><!-- 视图解析器:定义跳转的文件的前后缀 -->    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">    <property name="prefix" value="/view/" />    <property name="suffix" value=".html" />  <!--可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑  -->  </bean>    <mvc:default-servlet-handler />    </beans>

七：补齐自己的controller

package com.my.controller;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;@Controller
@RequestMapping("/user")
public class UserController {@RequestMapping(value="/getUserInfo")public String getUserInfo(HttpServletRequest request){System.out.println("==========");return "user";}
}

八：部署运行，输入http://localhost:8180/TestMaven2/user/getUserInfo访问。

一段可能会用到代码：maven依赖无法加入到工程时，在.classpath添加，很有用

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"><attributes><attribute name="maven.pomderived" value="true"/><attribute name="org.eclipse.jst.component.nondependency" value=""/></attributes></classpathentry>
