This approach is the same as JOIN FETCH in JPQL; however, this time, we are using the Criteria API of Hibernate. The following is an example of how to use JOIN FETCH in the Criteria API:

CriteriaBuilder criteriaBuilder = 
    getEntityManager().getCriteriaBuilder();
    CriteriaQuery<?> query = 
    criteriaBuilder.createQuery(Account.class);
    Root root = query.from(Account.class);
    root.fetch("transactions", JoinType.INNER);
    query.select(root);
    query.where(criteriaBuilder.equal(root.get("accountId"), 
    accountId));

    return (Account)this.getEntityManager().createQuery(query)
   .getSingleResult();

This option has the same advantages and disadvantages as JPQL. Most of the time, when we write a query using the Criteria API, it is use case-specific. So, this option might not be a huge problem in those cases, and it would be a good approach to reduce the amount of queries performed.
