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

You could do that too.

Repository:

`MyObject findByParameterOneAndParameterTwo( String parameterOne, String parameterTwo);`

if you pass a null parameterTwo, the generated JPQL will include the IS NULL condition:

`myobject0_.parameterTwo is null`

Ex: repository.findByParameterOneAndParameterTwo("D", null);
