Spring Boot 2.xx - 在 @ConditionalOnProperty 中結合 2 個條件

Question

我有以下界面：

@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> { }

當然這不會編譯。
我想要的只是以某種方式將這兩個@ConditionalOnProperty結合起來。 我應該使用@ConditionalOnExpression嗎？
提前致謝！

Answer 1

您可以使用AllNestedConditions組合兩個或多個條件：

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 {

    }

}

然后可以在您的存儲庫上使用此條件：

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