2.1 添加Maven依赖 !-- mysql db --dependencygroupIdmysql/groupIdartifactIdmysql-connector-java/artifactIdversion8.0.25/version/dependencydependencygroupIdcom.baomidou/groupIdartifactIdmybatis-plus-boot-starter/artifactIdversion3.5.1/version/dependency
2.2 修改配置文件
spring.datasource.urljdbc:mysql://127.0.0.1:3306/xx?useUnicodetruecharacterEncodingUTF-8
spring.datasource.usernamexx
spring.datasource.passwordxxxxx
spring.datasource.driver-classcom.mysql.cj.jdbc.Driver2.3 逆向代码生成(新增)
