1,mysql   2,tomcat  3,idea   4,spring

5,springmvc  6，springmvc   7,mybatis   8,maven

步骤：

1，建立数据库

JDBC---执行流程--》bean-->dao-->service--->controller-->页面

执行流程：页面----》controller-----》service----->dao--->bean

建立表

2，用maven创建项目

三

三，导包

pom.xml  修改文件

四；创建目录结构MVC

M-model

V-View

C-Contrallor

 

保证修改一处代码，不用修改其他代码

 

目录结构：

1，model/bean/entity实体

2,dao---与数据库交互

3，service业务逻辑层，dao的实现

4,controller控制器（springmvc)

 

五，编写实体类

User类，set,get,构造函数，属性

 

六，配置spring，mybatis

7，编写mapper

 

 

8，编写service

 

9,配置springmvc

 

 

10，配置tomcat
