Annotations: is there a way to set a prefix for embeddeed?

Is there a possibility to annotate an embedded component to use some prefix to be applied to column name? otherwise if you include a component more than once in the same entity you get name clashes.

example:

Code:

@Embeddable
public class RouteInfo {
    private Date   time;
    private Double   counterValue;
    private Double   cashAmount;

    // getters and setters here
}


@Entity
public class Route extends Persistent {
    private RouteDefinition routeDefinition;
    private String          note;

    private RouteInfo       startInfo   = new RouteInfo();

    private RouteInfo       finishInfo  = new RouteInfo();

    @Embedded
    @AttributeOverrides({ @AttributeOverride(name = "time", column = @Column(name = "start_time")),
                    @AttributeOverride(name = "cashAmount", column = @Column(name = "start_cashAmount")),
                    @AttributeOverride(name = "counterValue", column = @Column(name = "start_counterValue")) })
    public RouteInfo getStartInfo() {
        return startInfo;
    }

    @Embedded
    @AttributeOverrides({ @AttributeOverride(name = "time", column = @Column(name = "finish_time")),
                    @AttributeOverride(name = "cashAmount", column = @Column(name = "finish_cashAmount")),
                    @AttributeOverride(name = "counterValue", column = @Column(name = "finish_counterValue")) })
    public RouteInfo getFinishInfo() {
        return finishInfo;
    }

    // more getters and setters here
}

Any way to make it shorter? Annotations docs does not mention any possibility.

Awesome, so we'll be able to do this :

Code:

@Embeddable 
public class RouteInfo { 
    private Date   time; 
    private Double   counterValue; 
    private Double   cashAmount; 

    // getters and setters here 
} 


@Entity(access=AccessType.FIELD)
public class Route extends Persistent { 
    private RouteDefinition routeDefinition; 
    private String          note; 

    private RouteInfo       startInfo;

    private RouteInfo       finishInfo; 

    // more getters and setters here 
} 

soon?

I've commited it in HEAD as org.hibernate.test.annotations.strategy.DefaultComponentSafeNamingStrategy
