本文介绍如何在IntelliJ IDEA中从零开始搭建一个Maven Web项目，包括配置pom.xml、web.xml等关键文件，以及整合Spring、MyBatis等框架。
初学Maven，并且放弃了之前使用得Eclipse，利用IDEA开发。感受了一遍生无可恋得感觉，费劲两天时间总算把第一个项目成功发布了。写一点心得，希望能帮助到和我一样情况的朋友。
首先是如何创建Maven项目
1.FIle-New-Project-Maven
选择你的JDK,选择webapp模板，下一步
填写你的GroupId 和 ArtifactId Version不用改
点击+号 添加一项archetypeCatalogy = internal
如果不加 在创建模板时会很慢 具体原因
https://www.cnblogs.com/hihtml5/p/6305804.html 可以参考一下这个博客
然后是下一步 完成 等待项目模板构建完成
2.修改你的目录结构
自己生成的结构还缺少一些东西 需要自己补齐 resource（自动创建）里面写配置文件 Java（自己创建）里面写你的代码 WEB-INF下可以创建几个 css js jsp html(自己创建) 文件夹 放你相应的页面 terget不需要管 运行一遍项目后会自己创建
3.配置
接下来就是配置了 首先是 pom.xml
<?xml version="1.0" encoding="UTF-8"?> <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

然后是web.xml spring mybatis jdbc 的一些相关配置文件。大家可以用自己之前的项目直接复制文件就行
也可以粘贴我的 我把我的配置文件留下供参考
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" 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"> <display-name>ssm_bbs</display-name> <welcome-file-list> <welcome-file>login.jsp</welcome-file> </welcome-file-list> <!-- 加载spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/ApplicationContext-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- spirngMvc前端控制器 --> <servlet> <servlet-name>SpringMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 指定spring核心配置文件位置 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/SpringMvc.xml</param-value> </init-param> <!-- tomcat运行时加载这个servlet 12345 代表加载顺序 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>SpringMvc</servlet-name> <url-pattern>*.action</url-pattern> </servlet-mapping> <!-- 配置Post请求乱码 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
mybatis-config.xml

Spring.xml

然后完善你的项目 （有需要源码的可以找我要）
4.配置WEB 项目
快捷键 crtl+alt+shift+s 打开Project Struture---Artifact-----上方的+号 然后点图中的选项
选择你的项目 点OK
5.配置tomcat
点右上方的选项
点+号 ----Tomcat Server --- Local
配置下面信息
然后OK
启动你的Tomcat 测试
圆满结束 希望能对大家有帮助吧， 如有错误 各位及时指正
