Got number of type instead null

[RomaIvanovOfficial]

Hello!
I use JdbcTemplate in spring boot. Try to execute update request with null parameter, e.g.
update customer set name = null, isValid = null
And I got name = 12, isValid = -7 in my log. And in method beforeQuery(execInfo: ExecutionInfo, queryInfoList: List<QueryInfo>) in queryInfoList I see the same numbers of type.

I want to get log name = null, isValid = null

When setNull is called, there is a SetNullParameterValueConverter that handles formatting the null value.
For example, setNull(index,Types.VARCHAR) is converted to NULL(VARCHAR).
This is the default implementation.

When setXyz(index, null) is called, the following logic converts to the display value as null.

Lines 128 to 141 in 9601ff0

	protected String getParameterValueToDisplay(ParameterSetOperation param) {
	String value;
	if (ParameterSetOperation.isSetNullParameterOperation(param)) {
	// for setNull
	value = getDisplayValueForSetNull(param);
	} else if (ParameterSetOperation.isRegisterOutParameterOperation(param)) {
	// for registerOutParameter
	value = getDisplayValueForRegisterOutParameter(param);
	} else {
	value = getDisplayValue(param);
	}
	return value;
	}

You may have a custom converter, log entry creator, etc that simply shows an argument value.
In case it is not the case and the issue still persists, please provide a minimal sample project that reproduces the issue.
