We’re happy to announce the release of Hibernate OGM 5.3.1.Final.
This is the first maintenance release of the 5.3 branch.
What’s new compared to 5.3.0.Final?
This is a maintenance release fixing issues related to native queries pagination and projection.
Pagination now works perfectly for MongoDB native queries that use aggregates.
You can see a complete list of the changes in the release notes.
This version is fully compatible with 5.3.0.Final.
Projection and addEntity are not allowed in the same query
It is not possible anymore to execute a native query with projection and extract the returned values as an entity list.
Given the entity:
@Entity
public class Movie {
@Id
private Integer id;
private String name;
private String author;
private Integer year;
public Movie() {
}
}If we try to get all movies using projection and addEntity:
session.createNativeQuery( "db.Movie.find( {}, { 'id' : 1, 'name' : 1 } )" )
.addEntity( Movie.class )
.uniqueResult();An exception will be thrown and this message will be logged:
OGM000091: Projection and addEntity are not allowed in the same query on <Movie>It is allowed either to use projection without addEntity:
session.createNativeQuery( "db.Movie.find( {}, { 'id' : 1, 'name' : 1 } )" )
.uniqueResult();Or to use addEntity without projection:
session.createNativeQuery( "db.Movie.find( {} )" )
.addEntity( Movie.class )
.uniqueResult();This is true for all dialects supporting native queries, which at the moment of writing those lines are the MongoDB and Neo4j dialects.
This is consistent with the behavior of Hibernate ORM.
Where can I get it?
