JdbcTemplate queryForInt/Long is deprecated in Spring 3.2.2. What should it be replaced by?

What I think is that somebody realized that the queryForInt/Long methods has confusing semantics, that is, from JdbcTemplate source code you can see its current implementation:

@Deprecatedpublic int queryForInt(String sql, Object... args) throws DataAccessException {    Number number = queryForObject(sql, args, Integer.class);    return (number != null ? number.intValue() : 0);}

which may lead you to think that if the result set is empty it will return 0, however it throws an exception:

org.springframework.dao.EmptyResultDataAccessException: Incorrect result size: expected 1, actual 0

so the the following implementation is essentially equivalent to the current one:

@Deprecatedpublic int queryForInt(String sql, Object... args) throws DataAccessException {    return queryForObject(sql, args, Integer.class);}

And then the non deprecated code now must be replaced with the ugly:

    queryForObject(sql, new Object { arg1, arg2, ...}, Integer.class);

or this (nicer):

    queryForObject(sql, Integer.class, arg1, arg2, ...);

I agree with the original poster that deprecating the convenience method queryForLong(sql) is an inconvenience.

I had developed an app using Spring 3.1 and just updated to the latest Spring version (3.2.3) and noticed that it was deprecated.

Fortunately, it was a one line change for me:

return jdbcTemplate.queryForLong(sql);  // deprecated in Spring 3.2.x

was changed to

return jdbcTemplate.queryForObject(sql, Long.class);

And a couple of Unit Tests seem to indicate, the above change works.

Deprecated in favor of queryForObject(String, Class).
