Class Overview
Convenient super class for JDBC-based data access objects.
Requires a DataSource to be set, providing a
JdbcTemplate based on it to
subclasses through the getJdbcTemplate() method.
This base class is mainly intended for JdbcTemplate usage but can
also be used when working with a Connection directly or when using
org.springframework.jdbc.object operation objects.

Public Constructors
public JdbcDaoSupport ()
Public Methods
public final JdbcTemplate getJdbcTemplate ()
Return the JdbcTemplate for this DAO, pre-initialized with the DataSource or set explicitly.
public final void setDataSource (DataSource dataSource)
Set the JDBC DataSource to be used by this DAO.
public final void setJdbcTemplate (JdbcTemplate jdbcTemplate)
Set the JdbcTemplate for this DAO explicitly, as an alternative to specifying a DataSource.
Protected Methods
protected void checkDaoConfig ()
Abstract subclasses must override this to check their configuration.
Implementors should be marked as final
protected JdbcTemplate createJdbcTemplate (DataSource dataSource)
Create a JdbcTemplate for the given DataSource. Only invoked if populating the DAO with a DataSource reference!
Can be overridden in subclasses to provide a JdbcTemplate instance with different configuration, or a custom JdbcTemplate subclass.
Parameters
| dataSource | the JDBC DataSource to create a JdbcTemplate for |
|---|
Returns
- the new JdbcTemplate instance
See Also
protected final Connection getConnection ()
Get a JDBC Connection, either from the current transaction or a new one.
Returns
- the JDBC Connection
Throws
| CannotGetJdbcConnectionException | if the attempt to get a Connection failed |
|---|
See Also
protected final SQLExceptionTranslator getExceptionTranslator ()
Return the SQLExceptionTranslator of this DAO's JdbcTemplate, for translating SQLExceptions in custom JDBC access code.
See Also
protected void initTemplateConfig ()
Initialize the template-based configuration of this DAO. Called after a new JdbcTemplate has been set, either directly or through a DataSource.
This implementation is empty. Subclasses may override this to configure further objects based on the JdbcTemplate.
See Also
protected final void releaseConnection (Connection con)
Close the given JDBC Connection, created via this DAO's DataSource, if it isn't bound to the thread.
Parameters
| con | Connection to close |
|---|
