假设Person与语言有关，这就是您在较早的Hibernate中所做的事情：
Criteria criteria = entityManager.createCriteria(Person.class);Criteria languageCriteria = criteria.createCriteria("language");languageCriteria.add(Restrictions.like("locale", locale));criteria.add(Restrictions.like("name", name));criteria.add(Restrictions.between("time", startDate, endDate));criteria.addOrder(Order.asc("name"));我第一次尝试使用JPA 2.0：
CriteriaBuilder builder = entityManager.getCriteriaBuilder();CriteriaQuery<Person> criteria = builder.createCriteria(Person.class);Root<Person> pRoot = criteria.from(Person.class);Join<Person, Language> langJoin = criteria.join("language", JoinType.LEFT);Predicate conjunction = builder.conjunction();criteria.where(builder.and( builder.like(langJoin.get(Language_.locale), locale), builder.like(pRoot.get(Person_.name), name), builder.between(pRoot.get(Person_.time), startDate, endDate));criteria.orderBy(builder.asc(pRoot.get(Person_.name)));请让我知道这是否适合您。
编辑： 更新查询以仅使用一个
where呼叫。
