# 一、Eclipse #

**1.eclipse中配置maven插件**  
![这里写图片描述][SouthEast]  
**2.eclipse中配置仓库位置**  
![这里写图片描述][SouthEast 1]  
**3.构建索引**  
Window -> show view -> other -> 搜索maven

![这里写图片描述][SouthEast 3]  
**4.开始创建项目**  
选择Maven Project

**5.创建完成后，可以看到pom.xml文件报错缺少：web.xml文件**  
![这里写图片描述][SouthEast 7]  
手动在webapp下新建WEB-INF\\web.xml  
![这里写图片描述][SouthEast 8]  
再将web.xml文件的约束拷入即可  
`<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> </web-app>`  
**6.src/main/java创建一个Servlet的java文件**  
正常创建完servlet后发现报红，因为maven项目需要在pom.xml中填写servlet的坐标，引入servlet的依赖，从而导入jar包。  
填写依赖方式：  
①.直接在pom.xml的标签中加入：  
`<dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> </dependency>`  
②.用eclipse中dependencies查找本地仓库后引入

# 二、IntelliJ IDEA #

**1.IDEA中配置maven**  
![这里写图片描述][SouthEast 10]  
**2.maven创建web项目**  
![这里写图片描述][SouthEast 11]  
填写GroupId、ArtifactId、Version，一路next至finish。

**3.运行Java Web项目**  
①打开“Project Structure”，配置“Facets”  
![这里写图片描述][SouthEast 13]  
②配置“Artifacts”  
![这里写图片描述][SouthEast 14]  
③配置Tomcat服务器  
启动“Edit Configurations”  
![这里写图片描述][SouthEast 15]  
Add New ‘Tomcat Server’ Configuration  
![这里写图片描述][SouthEast 16]  
配置Deplyment
