Spring Boot 2.x.x - Combine 2 conditions in @ConditionalOnProperty

Question

I have the following interface :

@Primary
@ConditionalOnProperty(value = "ms.couchbase.enabled", havingValue = "true", matchIfMissing = true)
@ConditionalOnProperty(value = "iiams.switch.iiamsSingleProcessIdPer100", havingValue = "true", matchIfMissing = true)
public interface AsyncCommonRepository extends CouchbaseRepository<CouchbaseDocument, Long> { }

Of course this does not compile.
All I want is to combine somehow the two @ConditionalOnProperty. Should I use @ConditionalOnExpression?
Thanks in advance!

Answer 1

You can use AllNestedConditions to combine two or more conditions:

class AsyncCommonRepositoryCondition extends AllNestedConditions {

    AsyncCommonRepositoryCondition() {
        super(ConfigurationPhase.PARSE_CONFIGURATION);
    }

    @ConditionalOnProperty(value = "ms.couchbase.enabled", havingValue = "true", matchIfMissing = true)
    static class CouchbaseEnabled {

    }

    @ConditionalOnProperty(value = "iiams.switch.iiamsSingleProcessIdPer100", havingValue = "true", matchIfMissing = true)
    static class SingleProcessIdPer100 {

    }

}

This condition can then be used on your repository:

@Primary
@Conditional(AsyncCommonRepositoryCondition.class)
public interface AsyncCommonRepository extends CouchbaseRepository<CouchbaseDocument, Long> { }
