SSM+Maven+MySQL项目的搭建

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

 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)

　　<!-- 配置DispathcherServlet -->

        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

　　<!-- 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
