在Maven依賴關係中添加pubnub後，Spring啓動應用程序無法啓動

Question

我在maven中添加pubnub後，我的Spring啓動應用程序無法啓動。

這裏是我的pom.xml

我建微的服務，爲實時web應用程序，我想要使用pubnub發送通知到Web瀏覽器。 如果我刪除了pubnub，那麼它工作正常。 你能幫忙解決這個問題嗎？

Answer 1

似乎pubnub具有傳遞性依賴於：

<dependency> 
    <groupId>org.slf4j</groupId> 
    <artifactId>slf4j-nop</artifactId> 
    <version>1.7.21</version> 
    <scope>compile</scope> 
</dependency> 

如果您添加排除您pubnub性（請參閱here）它可能已經工作。但是，這可能會破壞pubnub中的日誌記錄：/ - 但我會試一試。
