JdbcTransactionManager

class JdbcTransactionManager(val connector: () -> Connection) : TransactionManager(source)

TransactionManager implementation based on JDBC.

This class is capable of working in any environment with any JDBC driver. It accepts a connector function used to obtain SQL connections. Applications should return a native JDBC connection in the callback function, no matter it's newly established by DriverManager directly, or obtained from a connection pool such as DataSource.

Database instances created by Database.connect functions use this implementation by default.
