## org.springframework.orm.hibernate3
Class LocalDataSourceConnectionProvider

    java.lang.Object
      org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider

All Implemented Interfaces:
  ConnectionProvider

Direct Known Subclasses:
  LocalJtaDataSourceConnectionProvider, TransactionAwareDataSourceConnectionProvider

    public class LocalDataSourceConnectionProvider

extends Object
implements ConnectionProvider

Hibernate connection provider for local DataSource instances in an application context. This provider will be used if LocalSessionFactoryBean's "dataSource" property is set without a Hibernate TransactionManagerLookup.

Since:
  1.2

  Juergen Hoeller

  `AbstractSessionFactoryBean.setDataSource(javax.sql.DataSource)`

Constructor Summary
`LocalDataSourceConnectionProvider()`

Method Summary
`void` `close()` This implementation does nothing: We're dealing with an externally managed DataSource.
`void` `closeConnection(Connection con)` This implementation simply calls `Connection.close`.
`void` `configure(Properties props)`
`Connection` `getConnection()` This implementation delegates to the underlying DataSource.
`DataSource` `getDataSource()` Return the DataSource that this ConnectionProvider wraps.
`protected DataSource` `getDataSourceToUse(DataSource originalDataSource)` Return the DataSource to use for retrieving Connections.
`boolean` `supportsAggressiveRelease()` This implementation returns `false`: We cannot guarantee to receive the same Connection within a transaction, not even when dealing with a JNDI DataSource.
