Configuring Annotations to be RUNTIME Retention By Default (without individual @Retention)

Is it possible to have a configuration where all Annotations of a given name or type are automatically RetentionPolicy.RUNTIME?



I came across a poblem where I need to use reflection at runtime to search for certain Annotations. But those are common Annotations scattered all over the app, such as @Service or @Transactional, and I can't go one by one and add @RetentionPolicy to each one, it would be too long.

          The Java Language Specification, section 9.6.4.2. @Retention states:




          If T does not have a (meta-)annotation m that corresponds to java.lang.annotation.Retention, then a Java compiler must treat T as if it does have such a meta-annotation m with an element whose value is java.lang.annotation.RetentionPolicy.CLASS.




          As you can see, it is a strict requirement that missing annotation is same as @Retention(RetentionPolicy.CLASS).



          If you need @Retention(RetentionPolicy.RUNTIME), then you must explicitly specify that.

                    What visual should I use to simply compare current year value vs last year in Power BI desktop

                    Image
                    0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

Trompette piccolo en si bémol, avec des branches d'embouchure différentes pour le si bémol (la plus courte) ou la (la plus longue) Trompette piccolo La trompette piccolo est la plus petite de la famille des trompettes. Elle joue une octave plus haut que la trompette standard en si bémol. La plupart des trompettes piccolo sont conçues pour jouer dans les deux tonalités de si bémol ou la, en utilisant une branche d'embouchure différente pour chaque tonalité. Le tube de la trompette piccolo en si bémol a une longueur moitié de celle de la trompette normale en si bémol. Des trompettes piccolo en sol, fa, ut sont également fabriquées, mais elles sont rares. La trompette soprano en ré, aussi connu comme la « trompette Bach », a été inventée vers 1890 par le facteur belge Victor-Charles Mahillon pour jouer les parties hautes de la trompette dans la musique de Bach et Haendel.
