If I use a @MappedSuperclass (which is a very useful annotation btw) I have to manually
copy any queries I want with taht class up to all subclasses. The binder should check any
mapped superclasses and pull those named queries up. i.e.
/**
* Base User class that different projects user classes derive from.
* Hibernate annotations doesn't pick up that query, so you have to copy it up to your
subclass
*/
@MappedSuperclass
@NamedQueries({
@NamedQuery(name="User.findByLoginName",
query="FROM User WHERE loginName = ?") // this is useless down here, i just
put it here for reference
})
public class BaseUser<PK extends Serializable> extends IdEntity<PK> {
private static final long serialVersionUID = -4443522925041212381L;
protected String loginName;
@Column(unique=true)
public String getLoginName() {
return this.loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
}
/**
* Custom user class for a certain application
*/
@Entity
@Table(name="tbl_user")
@GenericGenerator(name=IdGen.NAME, strategy=IdGen.AUTO)
@NamedQueries({
@NamedQuery(name="User.findByLoginName",
query="FROM User WHERE loginName = ?") // had to copy this up from the base
class
})
public class User extends BaseUser<Short> {
private static final long serialVersionUID = -6199544722824321999L;
private String firstName;
...
}
so in short it would be nice if the scanner would check for that and bind any named
queries up to the subclass
