文章目录

SSM框架：

  • Spring
  • SpringMVC
  • MyBatis

M: Model 模型层 [ MyBatis优化数据访问层 ]

  • 实体类
  • 业务逻辑层
  • 数据访问层

V: View 视图层 [ ]

显示数据
  • html
  • javaScript, vue

C: Controller 控制器 [ SpringMVC优化 ]

接受客户啊短的请求，响应到客户端的组件
  • Servlet
  • action

基于注解的SpringMVC框架开发的步骤

  1. 新建项目，选择webapp模板

  2. 修改目录，添加缺失的test,java,resources，并修改目录属性

  3. 修改pom.xml文件，添加SpringMVC,Servlet的依赖

  4. 添加springmvc.xml配置文件，指定包扫描，添加视图解析器

  5. 删除web.xml文件，新建web.xml

  6. 在web.xml文件中注册springMVC框架（所有的web请求都是基于servlet的）

  7. 删除index.jsp页面，并新建，发送请求给服务器

  8. 开发控制器（Servlet)，他是一个普通的类

  9. 添加tomacat进行测试
