SSM-网站后台管理系统制作(2)

SSM基本工作原理

   讲解网站:https://www.w3cschool.cn/wkspring/dcu91icn.html

构建基本工作环境:

    mysql

    eclipse(tomcat8.0)

    Hbulider(前端页面展示)

构建Dynamic Web Project,然后写基本所需的domain,dao,service,到此,基本功能即可实行,然后加入db.properties链接数据库,(applicationContext.xml,springmvc-config.xml,web.xml)就构建好了一个基本的ssm框架了。然后在Controller层里面加入所需要的代码即可,到此,一个基本的ssm就可以跑起来了,当然,这是简单讲解,3个xml里面还有很多需要学习的地方,相关问题见代码

  applicationContext.xml
