Add specification from a loop - jpa

Question

In a spring boot 3 application I try to use specification
public Page<User> advancedSearch(UserSearch search, Pageable page) {
String[] splittedValues = search.name.split(" ");
Specification<User> hasPersonWithName = (Root<User> root, CriteriaQuery<?> cq, CriteriaBuilder cb) -> {
...
return pre;
};
return findAll(specification, page);
}
I need for every value in splittedValues to add a global specification
for (String splittedName: splittedValues) {
specification.or(splittedName);
}
and pass it to findAll
I don't understand how to do it
Edit
you solution seem to work but
that generate
where
1=1
or like e1_0.name "%bob%"
or like e1_0.name "%jame%"
It's there a way to get
where
1=1
and (
like e1_0.name "%bob%"
or like e1_0.name "%jame%"
)

Answer 1

Using or operator , you combine multiple conditions, checking whether the name of User contains one of the splittedValues. Predicate is then returned from specification.
I hope that was what you wanted, in case I didn't understand, please correct me. Here is an example if so, adapt to your own code.
Edit: To get 1=1 and (like e1_0.name "%bob%" or like e1_0.name "%jame%"), you can use cb.or method to combine the conditions, resulting nameConditions is then combined with pre using cb.and.
public Page<User> advancedSearch(UserSearch search, Pageable page) {
String[] splittedValues = search.name.split(" ");
Specification<User> hasPersonWithName = (Root<User> root, CriteriaQuery<?> cq, CriteriaBuilder cb) -> {
Predicate pre = cb.conjunction();
Predicate nameConditions = null;
for (String splittedName: splittedValues) {
if (nameConditions == null) {
nameConditions = cb.like(root.get("name"), "%" + splittedName + "%");
} else {
nameConditions = cb.or(nameConditions, cb.like(root.get("name"), "%" + splittedName + "%"));
}
}
if (nameConditions != null) {
pre = cb.and(pre, nameConditions);
}
return pre;
};
return findAll(hasPersonWithName, page);
}
