Spring @ConfigurationProperties arbeitet sorgfältig, vielleicht falsch ⇐ Java

[Anonymous]

arbeitete an Konfigurationsklassen und entdeckte seltsames Verhalten. Vorbereiteter kleiner Test, um es zu reproduzieren: < /p>

Ich hatte erwartet, dass der Frühling einige davon injizieren kann, aber alle waren null.>
