篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了SSM+Maven+MySQL项目的搭建相关的知识，希望对你有一定的参考价值。
项目环境：Windows10+mysql5.7+Tomcat8.5+Maven3.6+IDER
Mysql / Tomcat / Maven的安装及配置在此省略
IDER创建一个maven-archetype-webapp项目
项目目录
java文件夹存放代码
resources中存放配置文件
WEB-INF存放受保护的页面(WEB-INF中的资源不可以通过浏览器地址栏直接访问)
pom.xml中的依赖包

jdbc.properties
#MySQL 连接配置 jdbc.driverClass=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8 jdbc.user=root jdbc.password=root
applicationContext.xml spring主配置文件

web.xml配置 (一般默认的version=“2.3” https://blog.csdn.net/molei199082/article/details/79956746 访问这个博客可以提供IDER修改web.xml版本的配置方法)

<!-- 指定匹配规则，默认将所有url请求都会转入到DispatcherServlet中去处理， 在spring-web中已经过滤掉一些请求了，因此这里可以直接这样配（/ 默认匹配所有请求） --> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
这些就是SSM框架的基本搭建
