JPA/Criteria API - Like & equal problem

Question

I\'m trying to use Criteria API in my new project:

public List findEmps(String name) {
    CriteriaBuilder cb = em.getCriteriaBuilder();
             


        

Answer 1

I tried all the proposals and although it did not give an error, it did not recover anything if I did not put all the expected text, in the end what was proposed by user3077341 worked for me but with the variant that I use '%' instead of "%", the like worked perfect.

List predicates = new ArrayList();
if(reference!=null){
    Predicate condition = builder.like(root.get("reference"),'%'+reference+'%');
    predicates.add(condition);
}
