Hi all,

 

I have done the following

 

1. Created org.hibernate.annotations.Column.java 

 (Well, I know its very minor task ;-) )

 

 

2. Understood code flow from

 

AnnotationConfiguration --> AnnotationBinder (bindClass and EJB3Column.buildColumnFromAnnotation)--> EntityBinder(processComplementaryTableDefinitions).

 

3. Specifically I understood how org.hibernate.annotations.Table (comment) works

 

 

Hence I tried to add column comment in similar fashion. The first hurdle I am facing is, the ColumnAnnotation class is not available at bindClass().

 

 

Here the code:

 

AnnotationBinder.java  {

 

---

bindClass(..) {

 

----

---

//add process complementary Table definition (index & all)

entityBinder.processComplementaryTableDefinitions( annotatedClass.getAnnotation( org.hibernate.annotations.

Table.class ) );

//Prasanna

org.hibernate.annotations.

Table tablecomment = annotatedClass.getAnnotation( org.hibernate.annotations.Table.class ) ;

if(null == tablecomment)

System.

out.println("Table annotation class not available");

else if(null!=tablecomment && null!=tablecomment.comment())

System.

out.println(" tablecomment :"+tablecomment.comment());

else

System.

out.println(" tablecomment not available");

org.hibernate.annotations.

Column columncomment = annotatedClass.getAnnotation( org.hibernate.annotations.Column.class ) ;

if(null == columncomment)

System.

out.println(" Column Annotation class not available");

else if(null != columncomment && null!=columncomment.comment())

System.

out.println(" columncomment :"+columncomment.comment());

else

System.

out.println(" column comment not available");

entityBinder.processComplementaryTableDefinitions( annotatedClass.getAnnotation( org.hibernate.annotations.

Tables.class ) );

}

 

 

 

}

 

 

 

Here I always get "Column Annotation class not available". But not so in case in table annotation. It perfectly works.

 

I tried adding Column Annotation class using AnnotationConfiguration --> addAnnotatedClass(..). But it didn't worked.

 

Please see the attachment for the relevant files.

Regards,

Prasanna

While not strictly useful for the comment feature, I want to add a
@ColumnOrFormula annotation to be able to support mixing formula and
columns in a user type (and a FK definition). Let's say it's a
lightly correlated feature.
