接口 SmartDataSource
- 所有超级接口:
CommonDataSource,DataSource,Wrapper
- 所有已知实现类:
SingleConnectionDataSource
public interface SmartDataSource extends DataSource
Extension of thejavax.sql.DataSourceinterface, to be implemented by special DataSources that return JDBC Connections in an unwrapped fashion.Classes using this interface can query whether or not the Connection should be closed after an operation. Spring's DataSourceUtils and JdbcTemplate classes automatically perform such a check.

方法详细资料
shouldClose
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.
- 参数:

- whether the given Connection should be closed
