Ensuring method ordering in an async method

Hi, I have a question on something. I have something like this: 
@Transactional
@Async 
Public void persistObjects() {
    List<Object> someObjects = apiService.getAllObjects(); 
        repo.saveObjects(someObjects); 
    otherApiService.loadObjects(someObjects); //How can I make sure this call is only called after saveObjects() is done completely mainly because this method is also currently async for performance benefits? 
}
@Transactional
@Async 
Public void persistObjects() {
    List<Object> someObjects = apiService.getAllObjects(); 
        repo.saveObjects(someObjects); 
    otherApiService.loadObjects(someObjects); //How can I make sure this call is only called after saveObjects() is done completely mainly because this method is also currently async for performance benefits? 
}

the method will execute in same order here unless is saveOjects also async? then you need to block until it finishes @Kale Vivi

saveObjects isn't async. Just realized you're right but one question. if there's an exception or any issue with the save and this is marked as transactional, it would roll back the changes and NOT execute the following load method right?
