eclipse 开发软件搭建简单 ssm 开源框架并连接MySQL查询

前提：准备好搭建框架的jar、连接数据库的jar、日志架包jar和tomcat

不多说我们开始

首先创建项目File -》New-》 Dynamic Web Project (名字随便起我这里就起 ssm )

在src下创建基本的包

技术分享图片

导入jar的包将jar包放进 WebContent -》web-INF -》lib里

(?? 一大堆不知道哪个没有用放进去就对了)

接着开始写配置文件

到这里配置文件就差不多了（配置文件的内容确实有点多我也没办法）

接着就开始建类文件

现在开始生成类和表mapper（如果生成不了我们也可以手动敲）
