java.lang.Object
   org.springframework.dao.support.DaoSupport
      org.springframework.jdbc.core.support.JdbcDaoSupport

All known Subclasses:   org.springframework.jdbc.core.simple.SimpleJdbcDaoSupport,  org.springframework.jdbc.core.namedparam.NamedParameterJdbcDaoSupport,
JdbcDaoSupport
abstract public class JdbcDaoSupport extends DaoSupport (Code)
Convenient super class for JDBC-based data access objects.

Requires a javax.sql.DataSource to be set, providing a org.springframework.jdbc.core.JdbcTemplate based on it to subclasses through the JdbcDaoSupport.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.

Method Summary
protected  voidcheckDaoConfig()
    
protected  JdbcTemplatecreateJdbcTemplate(DataSource dataSource)
     Create a JdbcTemplate for the given DataSource.
final protected  ConnectiongetConnection()
     Get a JDBC Connection, either from the current transaction or a new one.
final public  DataSourcegetDataSource()
     Return the JDBC DataSource used by this DAO.
final protected  SQLExceptionTranslatorgetExceptionTranslator()
     Return the SQLExceptionTranslator of this DAO's JdbcTemplate, for translating SQLExceptions in custom JDBC access code.
final public  JdbcTemplategetJdbcTemplate()
     Return the JdbcTemplate for this DAO, pre-initialized with the DataSource or set explicitly.
protected  voidinitTemplateConfig()
     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.

final protected  voidreleaseConnection(Connection con)
     Close the given JDBC Connection, created via this DAO's DataSource, if it isn't bound to the thread.
final public  voidsetDataSource(DataSource dataSource)
     Set the JDBC DataSource to be used by this DAO.
final public  voidsetJdbcTemplate(JdbcTemplate jdbcTemplate)
     Set the JdbcTemplate for this DAO explicitly, as an alternative to specifying a DataSource.



Method Detail
checkDaoConfig
protected void checkDaoConfig()(Code)



createJdbcTemplate
protected JdbcTemplate createJdbcTemplate(DataSource dataSource)(Code)
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 the new JdbcTemplate instance
See Also:   JdbcDaoSupport.setDataSource




getConnection
final protected Connection getConnection() throws CannotGetJdbcConnectionException(Code)
Get a JDBC Connection, either from the current transaction or a new one. the JDBC Connection
throws:
  CannotGetJdbcConnectionException - if the attempt to get a Connection failed
See Also:   org.springframework.jdbc.datasource.DataSourceUtils.getConnection(javax.sql.DataSource)



getDataSource
final public DataSource getDataSource()(Code)
Return the JDBC DataSource used by this DAO.



getExceptionTranslator
final protected SQLExceptionTranslator getExceptionTranslator()(Code)
Return the SQLExceptionTranslator of this DAO's JdbcTemplate, for translating SQLExceptions in custom JDBC access code.
See Also:   org.springframework.jdbc.core.JdbcTemplate.getExceptionTranslator



getJdbcTemplate
final public JdbcTemplate getJdbcTemplate()(Code)
Return the JdbcTemplate for this DAO, pre-initialized with the DataSource or set explicitly.



initTemplateConfig
protected void initTemplateConfig()(Code)
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:   JdbcDaoSupport.getJdbcTemplate()




releaseConnection
final protected void releaseConnection(Connection con)(Code)
Close the given JDBC Connection, created via this DAO's DataSource, if it isn't bound to the thread.
Parameters:
  con - Connection to close
See Also:   org.springframework.jdbc.datasource.DataSourceUtils.releaseConnection



setDataSource
final public void setDataSource(DataSource dataSource)(Code)
Set the JDBC DataSource to be used by this DAO.



setJdbcTemplate
final public void setJdbcTemplate(JdbcTemplate jdbcTemplate)(Code)
Set the JdbcTemplate for this DAO explicitly, as an alternative to specifying a DataSource.
