Examples of org.springframework.jdbc.datasource.SingleConnectionDataSource

org.springframework.jdbc.datasource.SingleConnectionDataSource
Implementation of {@link SmartDataSource} that wraps a single JDBC Connectionwhich is not closed after use. Obviously, this is not multi-threading capable.
Note that at shutdown, someone should close the underlying Connection via the close() method. Client code will never call close on the Connection handle if it is SmartDataSource-aware (e.g. uses DataSourceUtils.releaseConnection).
If client code will call close() in the assumption of a pooled Connection, like when using persistence tools, set "suppressClose" to "true". This will return a close-suppressing proxy instead of the physical Connection. Be aware that you will not be able to cast this to a native OracleConnection or the like anymore; you need to use a {@link org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractor} then.
This is primarily intended for testing. For example, it enables easy testing outside an application server, for code that expects to work on a DataSource. In contrast to {@link DriverManagerDataSource}, it reuses the same Connection all the time, avoiding excessive creation of physical Connections. @author Rod Johnson @author Juergen Hoeller @see #getConnection() @see java.sql.Connection#close() @see DataSourceUtils#releaseConnection @see org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractor
