这里的大多数答案都是误导性的，并提到标准查询比HQL慢，但事实并非如此。

如果你深入研究并执行一些测试，你会发现标准查询比常规HQL执行得更好。

同样，通过Criteria Query，你可以得到HQL所没有的面向对象的控制。

对于动态查询，我更喜欢使用条件查询。例如，根据某些参数，动态地添加一些排序或保留一些部分(例如限制)要容易得多。

另一方面，我使用HQL进行静态和复杂的查询，因为它更容易理解/阅读HQL。此外，我认为HQL更强大一些，例如对于不同的连接类型。

对于动态条件查询，我们可以根据我们的输入构造查询..在Hql查询是静态查询的情况下，一旦我们构造，我们就不能改变查询的结构。

HQL is to perform both select and non-select operations on the data, but Criteria is only for selecting the data, we cannot perform non-select operations using criteria HQL is suitable for executing Static Queries, where as Criteria is suitable for executing Dynamic Queries HQL doesn’t support pagination concept, but we can achieve pagination with Criteria Criteria used to take more time to execute then HQL With Criteria we are safe with SQL Injection because of its dynamic query generation but in HQL as your queries are either fixed or parametrized, there is no safe from SQL Injection.

为了两全其美，HQL的表达性和简洁性以及Criteria的动态特性可以考虑使用Querydsl。

Querydsl支持JPA/Hibernate, JDO, SQL和Collections。

我是Querydsl的维护者，所以这个答案是有偏见的。

We used mainly Criteria in our application in the beginning but after it was replaced with HQL due to the performance issues. Mainly we are using very complex queries with several joins which leads to multiple queries in Criteria but is very optimized in HQL. The case is that we use just several propeties on specific object and not complete objects. With Criteria the problem was also string concatenation. Let say if you need to display name and surname of the user in HQL it is quite easy (name || ' ' || surname) but in Crteria this is not possible. To overcome this we used ResultTransormers, where there were methods where such concatenation was implemented for needed result. Today we mainly use HQL like this:

String hql = "select " +
            "c.uuid as uuid," +
            "c.name as name," +
            "c.objective as objective," +
            "c.startDate as startDate," +
            "c.endDate as endDate," +
            "c.description as description," +
            "s.status as status," +
            "t.type as type " +
            "from " + Campaign.class.getName() + " c " +
            "left join c.type t " +
            "left join c.status s";

Query query =  hibernateTemplate.getSessionFactory().getCurrentSession().getSession(EntityMode.MAP).createQuery(hql);
query.setResultTransformer(Transformers.ALIAS_TO_ENTITY_MAP);
return query.list();

因此，在本例中，返回的记录是所需属性的映射。
