1.安装版本
使用官网安装docker pull apache/shardingsphere-proxy lasted 版本
2.server.xml配置如下：
3.config-encrypt.yaml配置如下：
4.已进行操作：
Navicat 测试连接shardingsphere-proxy时，在shardingsphere-proxy docker容器中提示如下：
请检查下 server.yaml 中 scaling 配置是否被打开了？
如果不是需要的功能，请将 scaling 配置注释。
你好，整个server.xml，我只配置如下信息（没有其他项目了）：
好的，我呼叫专家
你好，恢复默认的配置是得参考哪个？

好的，也是不行，请求专家支持，哈
把 TRANSACTION 配置打开呢，配置为 LOCAL
- !TRANSACTION
defaultType: LOCAL
Proxy 属性配置：

很遗憾没有见过你发的这个错误，同事反馈可能是数据库问题，建议换个 MySQL 实例试试？
因为 Docker 默认配置是有无数小伙伴在用的，没有报告过类似的问题
