How to add a dynamic where in #Query? - spring-boot

Question

I need to add my where conditions based in my filter object. If some value in the filter object is null, isn't necessary add the where condition of this parameter.
How to add a dynamic where?
Exemple:
FilterObject{
name: "Teste";
age: null;
}
#Query(value="SELECT id FROM user WHERE name = FilterObject.name", nativeQuery = true)
public List<User> getUsers(???)
Other example:
FilterObject{
name: "Teste";
age: 12;
}
#Query(value="SELECT id FROM user WHERE name = FilterObject.name AND age = FilterObject.age", nativeQuery = true)
public List<User> getUsers(???)
This is a highlevel example. Isnt the correct code. But... Is the necessary to understand my question
If a parameter of my filter is null this parameter isnt used in my where
Im Using spring boot with Spring Data JPA and my Query stay in my repository a Repository.

You can use Spring Data JPA specifications:
https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#specifications
You simply have to implement the method toPredicate:
Predicate toPredicate(Root<T> root, CriteriaQuery<?> query, CriteriaBuilder builder);
In this method you get root, query and the CriteriaBuilder to create a Criteria API where predicate.
Event methods like findAll take a Specification.
