[Springframework-developer] JDBC refactoring

[Rod J. <rod...@in...>]

Hi Guys,

I've done the following refactoring to the JDBC packages:

- Reworked SQLException translation. Now there's a SQLErrorCodes factory,
not a SQLExceptionTranslator factory. This allows the
SQLErrorCodeSQLExceptionTranslator to be subclassed for custom translation.
There's a new protected customTranslate() method for a first shot at
translation. If it returns null (as the SQLErrorCodeSQLExceptionTranslator
implementation does) resolution is via the codes. I've added tests for error
code lookup.

- Refactored the jdbc.object package to pull the JdbcTemplate field and
related properties into RdbmsOperation.

- This enables multiple RdbmsOperation objects to be created with one
JdbcTemplate. Instead of always creating their own JdbcTemplate, an
RdbmsOperation exposes a JdbcTemplate bean property and (for some
subclasses) constructor argument. This is appropriate for example if you
want to set up custom configuration in the JdbcTemplate such as custom
exception translators, warning policy etc.

I've improved the test suite. Hopefully there won't be any nasty surprises,
but please let me know if there are any implications I've overlooked.

Regards,
Rod
