idea2023根据表自动生成+springboot跑起来

1. idea安装插件
   
2. idea中显示数据库连接

就可以看到如下界面

选中你想生成的表，右键如下操作



如上就有了所有需要的后端代码

生成后，要查看一下mapper.xml中的文件是否 正确，若有误请先去修改，例如我的版本下生成了xml文件中缺乏逗号
4. 如上写好后想跑起来，配置pom,xml

6. 配置application.properties

server.port=8081

spring.datasource.url=jdbc:mysql://localhost:3306/ssm
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

mybatis.mapper-locations=classpath:mapper/*.xml

8. 修改 启动器类，增加dao层扫描
   

9. 如此就可以正常启动项目访问了
