javaWeb开发实战：spring MVC+MyBatis实现网页登录验证

1.环境和工具

Idea 2019、Tomcat 8、Jdk 8

2.新建spring MVC项目

打开idea，新建项目，选择springMVC->next:填写项目名、路径->finish完成创建

3.项目属性配置

文件（file）->项目结构：检查sdk、模块设置是否正确。

4.运行调试配置

Add configration

点击“+”号，选择tomcat->local

sserver信息填写

Deploymet页选择对应模块，保存

5.引入MyBatis框架

右键项目名->添加框架支持->maven

在生成的pom.xml中添加需要的依赖设置。

此处给出我常用的依赖配置
