Is annotating a class with @Transactional the same as annotating all its methods as @Transactional?

If I annotate a class with @Transactional like so:

@Transactional
class MyService { ... }

Is that the same as annotating all of its methods with @Transactional like so:

class MyService {
    @Transactional
    void myFunction() { ... }
}

There are also some other things to consider such as: how does this propagate to sub classes, inner classes, and static methods?

Solution

  • From the documentation

    …The result is that all methods are wrapped in a transaction and automatic rollback occurs if a method throws an exception (both Checked or Runtime exceptions) or an Error…

    So yes it is the same.

    how does this propagate to sub classes

    It is inherited - but it is recommended to annotate only concrete classes

    inner classes

    AFAIK not.
    If any I would only define POJOs as an inner class - business logic always goes into services

    static methods

    AFAIK not
