How to remove Hibernate deprecation warning message

Question

We have a query:

 List<Book> books = session.createQuery(
       "from Book b where :x member of b.bookCategories")
       .setParameter("x", crimeStory)
       .list();

But when executing this query, we got a warning message:

WARN 10:19:41 deprecation: HHH90000016: Found use of deprecated 'collection property' syntax in HQL/JPQL query [null.elements]; use collection function syntax instead [elements(null)].

I tried to change the query to:

List<Book> books = session.createQuery(
    "from Book b where ? in elements(b.bookCategories)")
    .setParameter(0, crimeStory).list();

but the warning message was still there.

Please help me to fix this warning.

P/s: We are currently using Hibernate 5.0.2

Answer 1

It is legal JPA and so should not be deprecated. See also http://download.oracle.com/otndocs/jcp/persistence-2.0-fr-oth-JSpec/ .

See https://hibernate.atlassian.net/browse/HHH-10621 for the JIRA about this bug.

You could just hide the message by adding log4j.logger.org.hibernate.orm.deprecation=error to your log4j.properties .

(I know this was an old question but it is used in the JIRA call)

Answer 2

Instead of using MEMBER OF , rather use an INNER JOIN . The JSQL should then be

from Book b inner join b.bookCategories bc where bc.id = :categoryId

Answer 3

As a side note, to simply hide (not fix) messages like this, as of 2017 and Log4j2 , use org.hibernate.orm.deprecation , for example:

<Logger name="org.hibernate.orm.deprecation" additivity="false" level="WARN">
    <RegexFilter regex=".*HHH90000016.*" onMatch="DENY" onMismatch="NEUTRAL"/>
    …
</Logger>

Be sure to use the specific code for your particular deprecation message, in this particular case it was HHH90000016 , but for Criteria-API deprecation warnings it would be HHH90000022 , and so on.

Or to disable all Hibernate deprecation messages (not recommended):

<Logger name="org.hibernate.orm.deprecation" additivity="false" level="ERROR">
    …
</Logger>
