Question

Starting a new project I’d like to use Hibernate annotations with MySQL instead of the configuration files I’ve used so far.
And I can’t seem to find the equivalent of:

    <id name="id" type="long" >
        <generator class="native"></generator>
    </id>

I tried using:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY, generator = "native")
private long id;

but got:

org.hibernate.AnnotationException: Unknown Id.generator: native

or:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;

Give me:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: PROCEDURE projectName.identity does not exist

Does anyone successfully deployed MySQL and Hibernate3 annotations for automatically generating ids?

Answer 1

Prior to version 5.0, using the strategy AUTO was the equivalent of using native in a mapping. This used the LegacyFallbackInterpreter:

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
public Long getId() {
    return id;
}

Since Hibernate 5.0, the default interpreter is the FallbackInterpeter which will either use a SEQUENCE generator or TABLE generator depending on the underlying database.

To use the LegacyFallbackInterpreter, set hibernate.id.new_generator_mappings to false.
