Spring JPA Query by Example returns no results

Question

I am using Spring's JPA ExampleMatcher without success.

So far, I have:

    ExampleMatcher matcher = ExampleMatcher.matching()
            .withIgnoreNullValues()
            .withMatcher("surname",  match -> match.contains().ignoreCase());
    Person p = new Person();
    v.setSurname("Sm");

Hoping to match Person objects whose surname field contains the specified substring.

But I consistently get no results.

On looking up the query log, can see why: at tries to match all the other fields too.

How can I get ExampleMatcher to ignore all other fields?

Use .withIgnorePaths() to ignore primitive fields in Person.

can'g it ignore all paths except those for which matchers are defined? The list of matchers is not constant. – NickJ Mar 02 '18 at 19:59

Could it be that you use primitive fields in `Person`? See https://stackoverflow.com/a/45230155/1602555. – Karol Dowbecki Mar 02 '18 at 20:01
Yes, I do have primitive fields. I have swapped them for the primitive wrapper objects. That did the trick! – NickJ Mar 02 '18 at 20:07
