Hibernate: Specification is the Spring Data wrapper around Criteria

interface OrderRepository extends JpaRepository<Order, Long>,
                                  JpaSpecificationExecutor<Order> { }

static Specification<Order> hasStatus(Status s) {
    return (root, q, cb) -> cb.equal(root.get("status"), s);
}
static Specification<Order> over(BigDecimal amount) {
    return (root, q, cb) -> cb.gt(root.get("total"), amount);
}

repo.findAll(hasStatus(PLACED).and(over(new BigDecimal("100"))));

select ... from orders where status=? and total>?
Each condition is a reusable, testable unit.
