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

Currently this is not possible in Spring-data-jpa.

There is a JIRA ticket regarding this which is still under investigation by the Spring team.

However if you want a workaround you can checkout a simple criteria query example.

Answer 2

I am new in Spring/JPA space,

use 'Query By Example'

i am using (in seviceImp) , all below arguments are optional/ depends on user choice

`
  .
    if (!firstName.isEmpty() ) {
    staff.setFirstName(firstName);
    }



    if (!lastName.isEmpty() ) {
    staff.setLastName(lastName);
    }

    if (!ptAadhar.isEmpty() ) {
        patient.setPtAadhar(ptAadhar);
    }

    if (!Cell.isEmpty() ) {
        staff.setCell(Cell);
    }


      Example<StaffEntity> example = Example.of(staff);  

      List<StaffEntity> staffList =staffRepository.findAll(example);
       .

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<Customer> findCustomerByNameAndEmail(@Param("name") String name, @Param("email") String email);
