Get early access and see previews of new features. Unable to acquire JDBC Connection; nested exception is org.hibernate.exception.JDBCConnectionException: Unable
java.sql.SQLSyntaxErrorException: Access denied for user 'service-account'@'%' to database 'our_database' The problem is that that specific exception is not being caught by the catch (Exception e) block in the above code.
Get early access and see previews of new features. [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]. I have tried this on old version of hibernate and it Hibernate wraps SQLExceptions thrown while interacting with the database in a JDBCException. In fact, Hibernate will attempt to convert the exception into a more meaningful subclass of JDBCException. The underlying SQLException is always available via JDBCException.getCause(). Data Access Objects (or DAOs for short) are used as a direct line of connection and communication with our database. DAOs are used when the actual CRUD (CRUD = Create, Read, Update, Delete) operations are needed and invoked in our Java code. These data access objects also represent the “data layer” of our application.
Sorted by: 15. The MySQL JDBC driver times out after 8 hours of inactivity and drops the connection. You can set autoReconnect=true in your JDBC URL, and this causes the driver to reconnect if you try to query after it has disconnected.
In addition to JDBC exceptions, Spring can also wrap Hibernate-specific exceptions, converting them from proprietary, checked exceptions (in the case of versions of Hibernate prior to Hibernate 3.0), to a set of focused runtime exceptions (the same is true for JDO and JPA exceptions).
I have a User object class which is was mapped using hbm.xml and the database is connecting fine, however returns the following error: ERROR: Syntax error: Encountered "USER" at line 1, column 13. Exception in thread "main" org.hibernate.exception.SQLGrammarException: could not prepare statement. GATPCcB.
