Remove boilerplate from db code

Question

It seems that every time I want to perform a db query, I have to write the following:

Connection conn = null;
Statement stmt = null;
ResultSet rset = null;

If you already have a DataSource you can use Spring JdbcTemplate for:

• greatly reduced boilerplate code
• have a good sql exception hierarchy to handle common database problems with specific runtime exceptions
• (later with further Spring usage) use declarative transaction management

If it seems too heavy for the moment you could implement some utility classes and methods for the 'boilerplate part'. Studying the source of JdbcTemplate should help in this case.
