Spring Data - ignore parameter if it has a null value

Question

I want to have a spring data repository interface that takes two parameters. Is there a way to make it have the following behaviour?

MyObject findByParameter         


        

Answer 1

Here is the way for do so:

@Query("SELECT c FROM Customer c WHERE (:name is null or c.name = :name) and (:email is null"
      + " or c.email = :email)")
    List findCustomerByNameAndEmail(@Param("name") String name, @Param("email") String email);
