expose ReflectionUtils.getDeclaredFields [SPR-17360]

[spring-projects-issues]

Caleb Cushing opened SPR-17360 and commented

I find myself fairly often wanting to do stuff like this

public static String[] getFieldNames( Class<?> clazz ) {
    return Stream.of( clazz.getDeclaredFields() ).map( Field::getName ).toArray( String[]::new );
}

however this is less efficient because it doesn't take advantage of a Field cache, I'd rather make use of Spring's Field Cache than use my own. So if I could write the following that'd be great.

public static String[] getFieldNames( Class<?> clazz ) {
    return Stream.of( ReflectionUtils.getDeclaredFfields(clazz) ).map( Field::getName ).toArray( String[]::new );

P.S. I understand Util is not generally meant as a published api, though I still think it should be (and possibly in it's own jar)
