Simplification layer over JdbcTemplate for Java 5 and above.

SimpleJdbcTemplate is a wrapper around JdbcTemplate that takes advantage of varargs and autoboxing. It also offers only a subset of the methods available on JdbcTemplate: Hence, it does not implement the JdbcOperations interface or extend JdbcTemplate, but implements the dedicated SimpleJdbcOperations interface.

If you need the full power of Spring JDBC for less common operations, use the `getJdbcOperations()` method of SimpleJdbcTemplate and work with the returned classic template, or use a JdbcTemplate instance directly.
