sqlex-mapper
Map java.sql.SQLException
to a more meaningful exceptions hierarchy
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.
Credits
Big 'thank you' goes to Spring Framework team for their implementation.
