EclipseLink set column name for @JoinColumn(name = “”) at runtime

问题

I need to change column names for all fields at runtime. I use eclipselink and do it via SessionCustomizer.

However, I can change column names for usual columns, those which are not in any relations.

Now I have a field in @ManyToOne relation and defines its column using @JoinColumn(name = "thisColumnToChage"). How to do it? This is my code:

private void setNameMaping(ClassDescriptor desc){
  desc.setTableName(NEW TABLE NAME);
 //setting columns for fields
  for (DatabaseMapping mapping : desc.getMappings()) {
    if (mapping.isDirectToFieldMapping()) {
         directMapping.getField().resetQualifiedName(NEW COLUM NAME);
    }else if (mapping.isManyToOneMapping()){
        ManyToOneMapping manyToOneMapping=(ManyToOneMapping)mapping;
         WHAT IS HERE?
      }
   }
}
