…nection pool - Add DB2-specific validation query "SELECT 1 FROM SYSIBM.SYSDUMMY1" - Same pattern as existing Oracle validation query handling - Fixes DB2 connection pool validation error when using datasource name Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Exclude Jetty jars to avoid version conflicts with public-module - Exclude SLF4J bindings to prevent multiple binding errors - Exclude Hadoop jars to use shared public-module versions These exclusions prevent class loading conflicts when JDBC engine starts and uses jars from both plugin lib and public-module.

…t database types - Add configuration parameter 'wds.linkis.jdbc.validation.query.mapping' - Default mapping: oracle:SELECT 1 FROM DUAL,db2:SELECT 1 FROM SYSIBM.SYSDUMMY1 - Remove hardcoded database-specific validation query logic - To add new database type, just update configuration, no code change needed Benefits: - Configuration-driven approach for extensibility - Easy to add support for new databases without modifying source code - Default values work for most common databases Usage example: Add to linkis-engineconn.properties: wds.linkis.jdbc.validation.query.mapping=oracle:SELECT 1 FROM DUAL,db2:SELECT 1 FROM SYSIBM.SYSDUMMY1,postgresql:SELECT 1 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
