Question

我正在尝试在我的应用中使用LocalDate和LocalDateTime和Java 8。我正在使用Hibernate 4.3.5和Spring。我按照这个有趣的教程here进行了所有工作但是当我使用DATE（）构造时我遇到了问题。

当我尝试做的时候：

SELECT * FROM TABLE WHERE DATE(data)=DATE(:data)

如果我手动创建的查询（复制和过去的查询Hibernate打印）工作正常，我也总是一个空列表。我认为问题是Hibernate在内部进行的转换;它尝试将LocalDate转换为java.util.Date。我告诉这个，因为如果我以这种方式更改查询：

SELECT * FROM TABLE WHERE DATE(data)=:data

我有这个例外：

java.lang.IllegalArgumentException: Parameter value [2014-05-27T00:00] did not match expected type [java.util.Date (n/a)]

我也做了这个测试：

TypedQuery<Date> test = manager.createQuery("select DATE(:test) FROM Appuntamento", Date.class);

    test.setParameter("test", LocalDate.now());
    for (Date t : test.getResultList()) {
        log.debug("T----------->" + t);
    }

不幸的是DATE（：test）总是空的!!

感谢任何建议

非常感谢

如果您使用JPA 2.1，这很简单。转换器允许JPA实体使用新的java.time.LocalDate和java.time.LocalDateTime类。只需定义所需的转换器类：

<强> LocalDatePersistenceConverter.java

import java.time.LocalDate;
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

@Converter
public class LocalDatePersistenceConverter implements AttributeConverter<LocalDate, java.sql.Date> {

  @Override
  public java.sql.Date convertToDatabaseColumn(LocalDate entityValue) {
    if (entityValue != null) {
      return java.sql.Date.valueOf(entityValue);
    }
    return null;
  }

  @Override
  public LocalDate convertToEntityAttribute(java.sql.Date databaseValue) {
    if (databaseValue != null) {
      return databaseValue.toLocalDate();
    }
    return null;
  }
}

<强> LocalDateTimePersistenceConverter.java

import java.time.LocalDateTime;
import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

@Converter
public class LocalDateTimePersistenceConverter implements AttributeConverter<LocalDateTime, java.sql.Timestamp> {

  @Override
  public java.sql.Timestamp convertToDatabaseColumn(LocalDateTime entityValue) {
    if (entityValue != null) {
      return java.sql.Timestamp.valueOf(entityValue);
    }
    return null;
  }

  @Override
  public LocalDateTime convertToEntityAttribute(java.sql.Timestamp databaseValue) {
    if (databaseValue != null) {
      return databaseValue.toLocalDateTime();
    }
    return null;
  }
}

然后使用@Converter注释注释适当的实体属性：

@Convert(converter = LocalDatePersistenceConverter.class)
private LocalDate completedDate;

Hibernate 5本身支持java 8 Date / Time API。只需确保hibernate-java8 jar在您的类路径上。

Answer 2

好消息

5.0.0.CR2开发版中不再需要转换器。根据官方网站，它支持java8特定的数据类型，包括java.time.LocalDate。

http://hibernate.org/orm/downloads/

改进了bootstrapping， hibernate-java8 ，hibernate-spatial，Karaf支持

Answer 3

Hibernate似乎不支持LocalTime，LocalDate和LocalDateTime。但是，您可以自己添加功能。

请参阅http://blog.progs.be/550/java-time-hibernate

Answer 4

您需要做的是将日期转换为字符串。您甚至可以使用java.time.LocalDate或java.time.LocalDateTime。

LocalDateTime myDate = LocalDateTime.of(2015, 04, 30, 15, 43, 12);

int numberOfIdOfDate = ((Long) session.createQuery(
   "SELECT count(*) FROM domain.PromoCard WHERE CREATE_DATE= :my_date")
   .setParameter("my_date", myDate.toString())
   .uniqueResult()).intValue();

log.info("Count of records with date '{}' is {}", myDate, numberOfIdOfDate);

输出：

[main] INFO myhibernate.PromoCardTest - Count of records with date '2015-04-30 15:43:12' is 6

Hibernate 4使用java.time.LocalDate和DATE（）构造
