public interface ConnectionCallback
Generic callback interface for code that operates on a JDBC Connection. Allows to execute any number of operations on a single Connection, using any type and number of Statements.
This is particularly useful for delegating to existing data access code
 that expects a Connection to work on and throws SQLException. For newly
 written code, it is strongly recommended to use JdbcTemplate's more specific
 operations, for example a query or update variant.

Object doInConnection(Connection con)
                      throws SQLException,
                             DataAccessException
JdbcTemplate.execute with an active JDBC
 Connection. Does not need to care about activating or closing the
 Connection, or handling transactions.
 If called without a thread-bound JDBC transaction (initiated by DataSourceTransactionManager), the code will simply get executed on the JDBC connection with its transactional semantics. If JdbcTemplate is configured to use a JTA-aware DataSource, the JDBC Connection and thus the callback code will be transactional if a JTA transaction is active.
Allows for returning a result object created within the callback, i.e.
 a domain object or a collection of domain objects. Note that there's special
 support for single step actions: see JdbcTemplate.queryForObject
 etc. A thrown RuntimeException is treated as application exception:
 it gets propagated to the caller of the template.
con - active JDBC Connection
null if none
SQLException - if thrown by a JDBC method, to be auto-converted
 to a DataAccessException by a SQLExceptionTranslator
DataAccessException - in case of custom exceptionsJdbcTemplate.queryForObject(String, Class),
