严重: Servlet.service() for servlet [springMvc] in context with path [/BimoAPI] threw exception [Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.TransactionException: JDBC begin transaction failed: ] with root cause
java.sql.SQLException: Couldn't perform the operation getAutoCommit: You can't perform any operations on this connection. It has been automatically closed by Proxool for some reason (see logs).
