org.springframework.jdbc.datasource

public Interface SmartDataSource

extends DataSource
Known Direct Implementers
org.springframework.jdbc.datasource.SingleConnectionDataSource
Imports
java.sql.Connection, javax.sql.DataSource
Extension of the javax.sql.DataSource interface, to be implemented by special DataSources that return JDBC Connections in an unwrapped fashion.

Classes using this interface can query whether the Connection should be closed after an operation. Spring's DataSourceUtils and JdbcTemplate classes automatically perform such a check.

Method Detail

public boolean shouldClose(Connection con)

Should we close this Connection, obtained from this DataSource?

Code that uses Connections from a SmartDataSource should always perform a check via this method before invoking close().

Note that the JdbcTemplate class in the 'jdbc.core' package takes care of releasing JDBC Connections, freeing application code of this responsibility.
