GreekPanda opened a new issue, #14238:
URL: https://github.com/apache/shardingsphere/issues/14238
## Bug Report
### Which version of ShardingSphere did you use?
shardingshpere 5.0.0
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
Can read the properties from nacos based on springcloud project successfully
### Actual behavior
Failed to parse properties from nacos
### Reason analyze (If you can)
Maybe confict with springboot starter?
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
I've made a sample nacos yml file based on official tutorials and build a
springcloud project using nacos as a register center. Try to do some test like
insert or select opertion. But it shows error:
