Method Summary

T	doInSqlMapClient(com.ibatis.sqlmap.client.SqlMapExecutor executor) Gets called by SqlMapClientTemplate.execute with an active SqlMapExecutor.

Method Detail

doInSqlMapClient

T doInSqlMapClient(com.ibatis.sqlmap.client.SqlMapExecutor executor)
                   throws SQLException

Gets called by SqlMapClientTemplate.execute with an active SqlMapExecutor. Does not need to care about activating or closing the SqlMapExecutor, 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 using 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 custom RuntimeException is treated as an application exception: It gets propagated to the caller of the template.

Parameters:

executor - an active iBATIS SqlMapSession, passed-in as SqlMapExecutor interface here to avoid manual lifecycle handling

Returns:

a result object, or null if none

Throws:

SQLException - if thrown by the iBATIS SQL Maps API
