提示：以下是本篇文章正文内容，下面案例可供参考

一、通过IDEA创建一个完整的springboot项目

1.File–>New–>Project；

2.选择Spring Initializr并配置项目信息，最后添加依赖并finish；

2.添加application.properties配置中mybatis的相关配置(否则会报错)；

#1.端口
server.port=8088
#2.MysqL配置信息
spring.datasource.url=jdbc:MysqL://localhost:3306/testkey?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
spring.datasource.driver-class-name=com.MysqL.cj.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=123456
#3.jsp调用相关
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

3.添加webapp目录（File->Project structrue）,添加路径\src\main\webapp；

4.添加相应的controller代码和jsp页面代码，目录结构如下；

5.pom.xml里添加相关依赖；
