Hibernate criteria query for ((C1 and C2) or C3) and C4

Question

        Predicate C= cb.conjunction();
        C.getExpressions().add(C1);
        C.getExpressions().add(C2)
        Predicate orCondition = cb.disjunction();
        orCondition.getExpressions().add(C3);
        orCondition.getExpressions().add(C);
        C4.getExpressions().add(orCondition);

But it is not working as expected.

I have tried with Criterion also,but it is could not add Criterion to hibernate Expressions. Also it is deprecated API.So,any help would be appreciated.

Answer 1

Shouldn't it rather be something like

Predicate innerAnd = cb.conjunction();
innerAnd.getExpressions().add(C1);
innerAnd.getExpressions().add(C2);

Predicate or = cb.disjunction();
or.getExpressions().add(innerAnd);
or.getExpressions().add(C3);

Predicate outerAnd = cb.conjunction();
outerAnd.getExpressions().add(or);
outerAnd.getExpressions().add(C4);

Your code rather leads to something like

C1 and C2 and C3

and I don't see C4 in your example.
