In one of my previous posts, I avoided auto-configuring primitives. Otherwise, the No qualifying bean error will occur. Today, I couldn’t avoid that anymore. I had to auto-configure a boolean so that the consumer can enable or disable a feature in application.yml.
So, how did I resolve this issue? I used @Value("{someKey:someDefault}") final boolean someFlag in the caller constructor.
Before that, I tried attaching only @Bean to the getter, but it didn’t work out. This article helped me demystify @Bean and @Qualifier, even if a little.
