Mixing annotations at field/setters

[doegi]

Hi!

I don't know wether this is a bug or required by the spec. However, I couldn't figure how to file it into JIRA as an unregistered user, and JIRA wouldn't let me register as a new user, so I have to post it here.

If you make differences in how you annotate the fields in
I have this simple class:

@Embeddable
public class BlaPK
 implements Serializable {

 private Long id;

 private Integer type = TYPE_UNSPECIFIED;

 @Column(name="bla_pk_id")
 public Long getId() {
 return id;
 }

 public void setId(Long id) {
 this.id = id;
 }


 @Column(name="bla_pk_type")
 public Integer getType() {
 return type;
 }
 public void setType(Integer type) {
 this.type = type;
 }
}


@Entity
public class Foo implements Serializable {
 @Id
 private Long id;

 @Embedded
 private BlaPK bla;

 // getters and setts for id/bla
}

JBoss will throw a "duplicate column id" error for class Foo. It doesn't seem to see the @Column name override in the @Embeddable class which are set on the getters.

This used to work in JBoss 4.0.3SP1. However, in 4.0.4RC1 I have to move the annotations in the BlaPK class to the fields as well. I have the impression JBoss makes a lookup for class Foo and sees field-wise annotations, and hence doesn't recognize the annocations at the functions when it inspects the @Embedded class.

I don't know if this required by the spec, if not, take this as a bug report (and again, sorry for not filing in JIRA).

The new spec by default does not allow mixed field and method access on an entity, it's mapped superclass and embedded entities. There is a way around this, if you really want to do it (check the spec).

Before, the @Entity annotation took an AccessType.FIELD or AccessType.METHOD attribute. This is no longer the case. The access type is now determined by whether you annotate the entity's @Id on the field or method. This is inherited by @Embeddable and when extending @MappedSuperclass.

Note that you can fall back to the previous behavior using @o.h.a.AccessType
