Method Detail

translate

public DataAccessException translate(String task,
                                     String sql,

Description copied from interface: SQLExceptionTranslator

Translate the given SQLException into a generic DataAccessException.

The returned DataAccessException is supposed to contain the original SQLException as root cause. However, client code may not generally rely on this due to DataAccessExceptions possibly being caused by other resource APIs as well. That said, a getRootCause() instanceof SQLException check (and subsequent cast) is considered reliable when expecting JDBC-based access to have happened.

Specified by:

translate in interface SQLExceptionTranslator

Parameters:

task - readable text describing the task being attempted

sql - SQL query or update that caused the problem (may be null)

ex - the offending SQLException

Returns:

the DataAccessException, wrapping the SQLException

Build a message String for the given SQLException.

Called when creating an instance of a generic DataAccessException class.

Parameters:

task - readable text describing the task being attempted

sql - the SQL statement that caused the problem. May be null.

ex - the offending SQLException

Returns:

the message String to use
