There was a problem hiding this comment. I don't think it'll be handy in all cases. There was a problem hiding this comment. @eugene-shevchenko any thoughts on that? There was a problem hiding this comment. The method uses only in java config, and as I mentioned earlier such bean definition hides component dependencies.

PS: It's sad that java config which should configure There was a problem hiding this comment. I think it's not a bad thing if we want to get rid of Spring one day. |
