Exception handling in JDBC is not easy. It provides base java.sql.SQLException with getSQLState and getErrorCode
information but it's vendor specific and cumbersome to use. Yes, JDBC 4 (since Java 6) provides some improvements
(additional exception hierarchy including classes like java.sql.SQLIntegrityConstraintViolationException etc.).
Unfortunately not all SQL vendors catched up with those improvements (e.g. PostgreSQL still uses
a single class
for all kinds of errors).
This projects borrows the idea and code from Spring Framework. It provides simplified version of SQLExceptionTranslator - SqlExceptionMapper.
The default implementation of SqlExceptionMapper provides translation similar to SQLErrorCodeSQLExceptionTranslator
and uses the same error codes mapping.
This is a very early version and API can still change.
Big 'thank you' goes to Spring Framework team for their implementation.
