Error querying database. Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is com.alibaba.druid.pool.DataSourceClosedException: dataSource already closed at xxxx
Contributor guide
Research direction
Start by reproducing the failure with Spring Boot DevTools restart and the Druid datasource, then trace the datasource lifecycle around restart. Done means the application can obtain JDBC connections after restart without a DataSourceClosedException.
