XxxxApplication.class啓動類

@SpringBootApplication
@MapperScan(value = "com.spade.test.mapper")
public class MybatisApplication {

    public static void main(String[] args) {
        SpringApplication.run(MybatisApplication.class, args);
    }
}

說明

全部加載完成後
1.更改數據庫連接信息
2.配置generatorconfig.xml中的table標籤
3.運行插件,生成實體類/mapper接口/mapper.xml文件
