名为Discount的实体中的属性声明如下。
@Column(name = "discount_start_date")
private LocalDateTime discountStartDate; // Getter & setter.
MySQL中的TIMESTAMP类型。我需要在某处根据给定字段discount_start_date的日期部分搜索行列表，忽略该字段的时间部分（这只是一个示例）。
从java.time.LocalDateTime到java.sql.Timestamp的转换和反之亦然由JPA（2.1）转换器透明处理。
以下尝试肯定会失败。
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy hh:mm:ss a Z");
LocalDateTime dateTime = LocalDateTime.parse("25-Feb-2016 00:52:33 AM +0000", formatter); // This is submitted by clients.
Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone(ZoneOffset.UTC));
calendar.setTime(Date.from(dateTime.toInstant(ZoneOffset.UTC)));
TypedQuery<Discount> query = entityManager.createQuery("SELECT d FROM Discount d WHERE d.discountStartDate >= :param", Discount.class);
List<Discount> list = query.setParameter("param", calendar, TemporalType.DATE).getResultList();
查询失败，出现以下异常。

Parameter<Calendar> parameter = criteriaBuilder.parameter(Calendar.class);
criteriaQuery.where(criteriaBuilder.greaterThanOrEqualTo(root.get(Discount_.discountStartDate), parameter));
List<Discount> list = entityManager.createQuery(criteriaQuery).setParameter(parameter, calendar, TemporalType.DATE).getResultList();
第二行不会编译，因为Discount_.discountStartDate指向的SingularAttribute<Discount, LocalDateTime>与Parameter<Calendar>不匹配，作为greaterThanOrEqualTo()的参数。
根据TIMESTAMP类型字段的日期部分提取结果的方法是什么？
它可能适用于目标实体本身使用@Temporal(TemporalType.TIMESTAMP)指定的字段，但它需要进行更改，这使我们无法灵活地使用autoApply设置为true的标准JPA转换器。
TypedQuery<X>接口没有重载的setParameter()方法，因为现在接受来自Java SE 8的JavaTime API的java.time.LocalDateTime类型的参数，原因显而易见。
public <T extends Object> TypedQuery<X> setParameter(Parameter<T> param, T value);
public TypedQuery<X> setParameter(Parameter<Calendar> param, Calendar value, TemporalType temporalType);
public TypedQuery<X> setParameter(Parameter<Date> param, Date value, TemporalType temporalType);
public TypedQuery<X> setParameter(String name, Object value);
public TypedQuery<X> setParameter(String name, Calendar value, TemporalType temporalType);
public TypedQuery<X> setParameter(String name, Date value, TemporalType temporalType);
public TypedQuery<X> setParameter(int position, Object value);
public TypedQuery<X> setParameter(int position, Calendar value, TemporalType temporalType);
public TypedQuery<X> setParameter(int position, Date value, TemporalType temporalType);
那么，在JPA的下一个版本发布之前没有解决方法吗？

CriteriaBuilder具有日期转换功能：参考：how to find by date from timestamp column in JPA criteria。您可以使用它们来构建谓词：
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Discount> q = cb.createQuery(Discount.class);
Root<Discount> d = q.from(Discount.class);
// split up localdatetime field.
Path<LocalDateTime> ldt = d.<LocalDateTime>get("localDataTime");
Expression<Integer> dbYear = cb.function("year", Integer.class, ldt);
Expression<Integer> dbMonth = cb.function("month", Integer.class, ldt);
Expression<Integer> dbDay = cb.function("day", Integer.class, ldt);
// build query
q.select(d).where(cb.equal(dbYear, 2016), cb.equal(dbMonth, 3), cb.equal(dbDay, 11));
Discount r = em.createQuery(q).getSingleResult();
System.out.println(r);
这将产生以下SQL：
select
discount0_.id as id1_0_,
discount0_.localDataTime as localDat2_0_
from
Discount discount0_
where
extract(year from discount0_.localDataTime)=2016
and extract(month from discount0_.localDataTime)=3
and extract(day from discount0_.localDataTime)=11

尝试使用Expression.as()
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery<Discount> criteriaQuery = criteriaBuilder.createQuery(Discount.class);
Root<Discount> root = criteriaQuery.from(entityManager.getMetamodel().entity(Discount.class));
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy hh:mm:ss a Z");
LocalDateTime dateTime = LocalDateTime.parse("25-Feb-2016 00:52:33 AM +0000", formatter);
Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone(ZoneOffset.UTC));
calendar.setTime(Date.from(dateTime.toInstant(ZoneOffset.UTC)));
ParameterExpression<Calendar> parameter = criteriaBuilder.parameter(Calendar.class);
criteriaQuery.where(criteriaBuilder.greaterThanOrEqualTo(root.get(Discount_.discountStartDate).as(Calendar.class), parameter));
List<Discount> list = entityManager.createQuery(criteriaQuery).setParameter(parameter, calendar, TemporalType.DATE).getResultList();
在查询的.as(Calendar.class)子句中注意WHERE。它生成以下SQL查询。
select
discount0_.`discount_id` as discount1_12_,
discount0_.`discount_code` as discount2_12_,
discount0_.`discount_end_date` as discount3_12_,
discount0_.`discount_percent` as discount4_12_,
discount0_.`discount_start_date` as discount5_12_,
discount0_.`row_version` as row_vers6_12_
from
`jboss_projectdb`.`discount` discount0_
where
cast(discount0_.`discount_start_date` as datetime)>=?
请注意，Hibernate提供程序会将列强制转换为datetime - cast(discount0_.discount_start_date as datetime)，这不是我们感兴趣的。
我们要么
cast(discount0_.`discount_start_date` as date)
或
date(discount0_.`discount_start_date`)
两种可能的方法。
按如下方式处理CriteriaBuilder.function()。
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery<Discount> criteriaQuery = criteriaBuilder.createQuery(Discount.class);
Root<Discount> root = criteriaQuery.from(entityManager.getMetamodel().entity(Discount.class));
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy hh:mm:ss a Z");
dateFormat.setTimeZone(TimeZone.getTimeZone(ZoneOffset.UTC));
Date date = dateFormat.parse("25-Feb-2016 00:52:33 AM +0000");
Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone(ZoneOffset.UTC));
calendar.setTime(date);
Expression<Calendar> function = criteriaBuilder.function("date", Calendar.class, root.get(Discount_.discountStartDate));
ParameterExpression<Calendar> parameter = criteriaBuilder.parameter(Calendar.class);
criteriaQuery.where(criteriaBuilder.greaterThanOrEqualTo(function, parameter));
List<Discount> list = entityManager.createQuery(criteriaQuery).setParameter(parameter, calendar, TemporalType.DATE).getResultList();
它生成以下SQL语句。
select
discount0_.`discount_id` as discount1_12_,
discount0_.`discount_code` as discount2_12_,
discount0_.`discount_end_date` as discount3_12_,
discount0_.`discount_percent` as discount4_12_,
discount0_.`discount_start_date` as discount5_12_,
discount0_.`row_version` as row_vers6_12_
from
`jboss_projectdb`.`discount` discount0_
where
date(discount0_.`discount_start_date`)>=?
然而，上述方法与标准查询本身嵌入的底层数据库函数date()略有结合，从而影响了可移植性。
因此，更可行的方法是使用.as(java.sql.Date.class)如下。
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery<Discount> criteriaQuery = criteriaBuilder.createQuery(Discount.class);
Root<Discount> root = criteriaQuery.from(entityManager.getMetamodel().entity(Discount.class));
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy hh:mm:ss a Z");
dateFormat.setTimeZone(TimeZone.getTimeZone(ZoneOffset.UTC));
Date date = dateFormat.parse("25-Feb-2016 00:52:33 AM +0000");
ParameterExpression<Date> parameter = criteriaBuilder.parameter(Date.class);
criteriaQuery.where(criteriaBuilder.greaterThanOrEqualTo(root.get(Discount_.discountStartDate).as(java.sql.Date.class), parameter));
List<Discount> list = entityManager.createQuery(criteriaQuery).setParameter(parameter, date, TemporalType.DATE).getResultList();
这在不同的RDBMS中是完全可移植的。它生成以下SQL查询。
select
discount0_.`discount_id` as discount1_12_,
discount0_.`discount_code` as discount2_12_,
discount0_.`discount_end_date` as discount3_12_,
discount0_.`discount_percent` as discount4_12_,
discount0_.`discount_start_date` as discount5_12_,
discount0_.`row_version` as row_vers6_12_
from
`jboss_projectdb`.`discount` discount0_
where
cast(discount0_.`discount_start_date` as date)>=?
Java文档中有关于Expression.as()的注意事项。
对表达式执行类型转换，返回一个新表达式 宾语。此方法不会导致类型转换：运行时类型 没有改变。 警告：可能会导致运行时失败。
然而，这不会影响这种特殊情况，因为我们知道我们期望它投射到什么类型。
在java.time.LocalDateTime / java.time.ZonedDateTime和java.util.Date或java.util.Calendar之间切换是一个独特的故事。因此，为了简洁起见，该部分已完全排除在此答案之外。
