老师您好我这边启动MallGoods服务遇到两个问题

使用Druid数据源时启动报错：

java.lang.NoClassDefFoundError: org/springframework/boot/bind/RelaxedDataBinder

搜索了一下发现似乎因为Druid不兼容springboot 2.x, 请问老师您是否遇到这个问题呢？

注释掉Druid依赖，服务可以启动，不过运行后，控制台log如下error

由于课程推进到这里还没有涉及到nacos的内容，因此我使用了file方式进行配置，且服务端启动是成功的：

23:14:59.028  INFO --- [                     main] io.seata.config.FileConfiguration        : The file name of the operation is registry

23:14:59.129  INFO --- [                     main] io.seata.config.FileConfiguration        : The file name of the operation is file.conf
23:14:59.129  INFO --- [                     main] io.seata.config.FileConfiguration        : The configuration file used is /usr/local/seata/seata/seata-server-1.4.2/conf/file.conf
23:14:59.687  INFO --- [                     main] com.alibaba.druid.pool.DruidDataSource   : {dataSource-1} inited

请问老师，是否要添加一些配置项在项目中呢？
期待老师的解答~ （和新版本的代码）
