# Package org.springframework.jdbc.datasource

Provides a utility class for easy DataSource access, a PlatformTransactionManager for a single DataSource, and various simple DataSource implementations.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  ConnectionHandle | Simple interface to be implemented by handles for a JDBC Connection.
  ConnectionProxy | Subinterface of `Connection` to be implemented by Connection proxies.
  SmartDataSource | Extension of the `javax.sql.DataSource` interface, to be implemented by special DataSources that return JDBC Connections in an unwrapped fashion.

- Class Summary
  Class | Description
  --- | ---
  AbstractDataSource | Abstract base class for Spring's `DataSource` implementations, taking care of the padding.
  AbstractDriverBasedDataSource | Abstract base class for JDBC `DataSource` implementations that operate on a JDBC `Driver`.
  ConnectionHolder | Connection holder, wrapping a JDBC Connection.
  DataSourceTransactionManager | `PlatformTransactionManager` implementation for a single JDBC `DataSource`.
  DataSourceUtils | Helper class that provides static methods for obtaining JDBC Connections from a `DataSource`.
  DelegatingDataSource | JDBC `DataSource` implementation that delegates all calls to a given target `DataSource`.
  DriverManagerDataSource | Simple implementation of the standard JDBC `DataSource` interface, configuring the plain old JDBC `DriverManager` via bean properties, and returning a new `Connection` from every `getConnection` call.
  IsolationLevelDataSourceAdapter | An adapter for a target `DataSource`, applying the current Spring transaction's isolation level (and potentially specified user credentials) to every `getConnection` call.
  JdbcTransactionObjectSupport | Convenient base class for JDBC-aware transaction objects.
  LazyConnectionDataSourceProxy | Proxy for a target DataSource, fetching actual JDBC Connections lazily, i.e.
  SimpleConnectionHandle | Simple implementation of the `ConnectionHandle` interface, containing a given JDBC Connection.
  SimpleDriverDataSource | Simple implementation of the standard JDBC `DataSource` interface, configuring a plain old JDBC `Driver` via bean properties, and returning a new `Connection` from every `getConnection` call.
  SingleConnectionDataSource | Implementation of `SmartDataSource` that wraps a single JDBC Connection which is not closed after use.
  TransactionAwareDataSourceProxy | Proxy for a target JDBC `DataSource`, adding awareness of Spring-managed transactions.
  UserCredentialsDataSourceAdapter | An adapter for a target JDBC `DataSource`, applying the specified user credentials to every standard `getConnection()` call, implicitly invoking `getConnection(username, password)` on the target.
  WebSphereDataSourceAdapter | `DataSource` implementation that delegates all calls to a WebSphere target `DataSource`, typically obtained from JNDI, applying a current isolation level and/or current user credentials to every Connection obtained from it.
