Can you specify multiple @Conditional annotations?

Question

With Spring Boot, can one use multiple @Conditional annotations on one @Bean definition? If so, is there a predictable order that they are resolved? In other words, can I specify both @ConditionalOnResource and @ConditionalOnMissingBean on the same @Bean def? Which one would take precedence?

I'm using Spring Boot 1.0.2.RELEASE.

Do you have any special reason that would make the order of conditional evaluations relevant? — geoand, Jul 06 '14 at 14:49
No, you're right. Looking at my case again, the order is not important, so long as the behavior that Dave describes below is accurate, that should be fine for me. — Justin Miller, Jul 06 '14 at 17:44

I don't think the order is important: any Condition that doesn't match will cause the bean to be omitted. If they all match, it will be included.

How can we define multiple @Conditional annotation in Spring 4.0? – Sahil Chhabra Mar 27 '17 at 07:08
Is it possible to express an OR relation such as `@ConditionalOnProperty` OR `@ConditionalOnMissingBean`? – lanoxx Mar 17 '18 at 09:23

Have a look at the javadoc for `AnyNestedCondition` – Dave Syer Mar 17 '18 at 12:58
