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

Question

I'm trying to use LocalDate and LocalDateTime with Java 8 in my app. I'm using Hibernate 4.3.5 and Spring. I followed this interesting tutorial here and all works but I've a problem when I use DATE() construct.

When I try to do:

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

I've always an empty list also if the query I made manually (copy and past query Hibernate print) works fine. I think that the problem is the conversion that Hibernate do internally; it try to convert LocalDate to java.util.Date. I tell this because if I change the query in this way:

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

I've this exception:

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

I made also this test:

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);
    }

And unfortunally DATE(:test) is always null!!

Any suggestion is appreciated

Thanks very much

Answer 1

If you use JPA 2.1 this is simple to do. Converters allow your JPA entities to use the new java.time.LocalDate and java.time.LocalDateTime classes. Simply define the needed converter classes:

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;
  }
}

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;
  }
}

And then annotate the appropriate entity property with the @Converter annotation:

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

Update September 2015
Hibernate 5 natively supports the java 8 Date/Time APIs. Just ensure that the hibernate-java8 jar is on your class path.

Answer 2

GOOD NEWS

There is no longer need for converters in the 5.0.0.CR2 development version. According to the official site, it supports the java8 specific data types, including java.time.LocalDate.

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

Improved bootstrapping, hibernate-java8 , hibernate-spatial, Karaf support

Answer 3

It appears that LocalTime, LocalDate, and LocalDateTime are not supported in Hibernate. You can, However add the functionality yourself.

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

Answer 4

What you've got to do is convert the date into String. You may even use the java.time.LocalDate or 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);

Output:

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