Interface SqlMapCallback

public interface SqlMapCallback

Callback interface for data access code that works on an iBATIS Database Layer SqlMap. To be used with SqlMapTemplate's execute method, assumably often as anonymous classes within a method implementation.

public Object doInMappedStatement(MappedStatement stmt, Connection con)
                            throws java.sql.SQLException

Gets called by SqlMapTemplate.execute with an active JDBC Connection. Does not need to care about the lifecycle of the Connection or handling transactions.

If called without a thread-bound JDBC transaction (initiated by DataSourceTransactionManager), the code will simply get executed on the underlying JDBC connection with its transactional semantics. If SqlMapTemplate 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. A thrown RuntimeException is treated as application exception, it gets propagated to the caller of the template.

Parameters:

stmt - the iBATIS Database Layer mapped statement

con - the JDBC Connection to work on

Returns: a result object, or null if none

Throws:

SQLException - if thrown by MappedStatement methods
