https://github.com/apache/shardingsphere/issues/38336#issuecomment-3996361621
The root cause is that after upgrading to 5.5.3, shardingsphere-jdbc changed
from “bundling many dependencies by default” to a “core + optional plugins”
model.
Your config uses Hikari + SQL Server + ZooKeeper (Cluster), but the
required optional plugins were not fully included. As a result, some SPI
components were missing at runtime, and startup failed during pool
initialization.
For your setup, you should include at least these dependencies:
1. org.apache.shardingsphere:shardingsphere-infra-data-source-pool-hikari
2. org.apache.shardingsphere:shardingsphere-jdbc-dialect-sqlserver (and
keep com.microsoft.sqlserver:mssql-jdbc)
3.
org.apache.shardingsphere:shardingsphere-cluster-mode-repository-zookeeper
(because mode.repository.type=ZooKeeper)
The most direct missing dependency behind this specific error is item #1
(as confirmed by your own issue comment after adding it).
