Spring Data JPA ignore null parameter

Say i have the below JPA method :

public List<FrequencyCode> findAllByNameContainingAndAllowExplicitDosingTimesEqualsOrderByName(String name, Boolean allowExplicitDosingTimes); 

This method is called by a user filtering a list of these objects with an input field and a select field :

The boolean value can be true, false or null in this case if the user is not making a search with that field. It looks like JPA is ACTUALLY searching for a null value when i would like it to ignore any null values. I have been able to make this combined search work with the below code :

@Override public List<FrequencyCode> findAllWithFilters(String name, Boolean allowExplicitDosingTimes) { if (allowExplicitDosingTimes == null) { return ((FrequencyCodeRepository) baseRepository).findAllByNameContainingOrderByName(name); } else if (allowExplicitDosingTimes == true) { return ((FrequencyCodeRepository) baseRepository).findAllByNameContainingAndAllowExplicitDosingTimesTrueOrderByName(name); } else if (allowExplicitDosingTimes == false) { return ((FrequencyCodeRepository) baseRepository).findAllByNameContainingAndAllowExplicitDosingTimesFalseOrderByName(name); } return null; } 

This works but, obviously, on a page with 8 search options this would become a nightmare. The String parameters do not have this problem because they are actually an empty String when the user doesn't choose a filter. This paired with the Containing keyword, any value contains "" so it behaves as if that parameter is ignored which is exactly what I want for other types. Is there a way for a JPA findAll...() method to simply ignore null parameters?

******SOLUTION******

Here is how i made this work with the help of the accepted answer :

FrequencyCode fc = new FrequencyCode(); fc.setName(name); fc.setAllowExplicitDosingTimes(allowExplicitDosingTimes); ExampleMatcher matcher = ExampleMatcher.matching() .withMatcher("name", match -> match.contains()) .withMatcher("allowExplicitDosingTimes", match -> match.exact()) .withIgnorePaths("id", "uuid") .withIgnoreNullValues(); Example<FrequencyCode> example = Example.of(fc, matcher); List<FrequencyCode> frequencyCodes = ((FrequencyCodeRepository) baseRepository).findAll(example); 

You HAVE to tell it to ignore any ID fields or really any other fields you do not intend to search with but this is INCREDIBLY powerful!

Thanks!
