Resolved - @PreUpdate not working in JUnit test.

 



javax.persistence.PreUpdate





object need to be "dirty" to trigger...


obj.setColumn01("text");
repo.save(obj);


then make obj "dirty" before save to trigger @PreUpdate


obj.setColumn01("new text);
repo.save(obj);




Solution

As you said, the callback method is called the second time, if the entity is detached or fetched again from DB.

I cannot explain it exactly, but can think of the scenario described here, when no dirty fields are identified before the second save() call and thus the @PreUpdate callback not called. Or it may be simply a bug within your version of EclipseLink.
