1.new project 如下:
2.next 到下一步 对应的项目名,包名可以改一下
3.下一步 对应web 以及 如图 SQL勾选一下
4. 下一步 如图所示 ,点击完成 加载完成 ,此时右侧有64个架包
5.配置pom.xml文件 加载完成后有76个架包

7. 在main下面建一个webapp文件夹
8. 选中Facets 配置webapp文件
9.创建如下包名
10.在templates里面配置mybatis-generator-config.xml文件
<?xml version="1.0" encoding="UTF-8"?>

</generatorConfiguration>
10.在pom.xml中把文件配置路径改一下 如图
11.配置application.properties文件

#设置jsp 访问资源前缀
spring.mvc.view.prefix=/WEB-INF/views/
#设置jsp 访问资源后缀
spring.mvc.view.suffix=.jsp
11.在Springboot03Application文件夹中加入如下语句
12. 13.运行一下Unnamed
自动创建po层和dao层
12.如图运行
即为配置成功
13.配置热启动插件
快捷键ctrl+shift+A
如上图所示,配置完成
