spring boot + apache camel + mongodb集成問題

Question

剛開始，我是apache camel的新手。 我有一個spring boot（MVC）+ mongodb項目已經運行正常，當我嘗試將它與apache camel集成時，我在控制台上遇到異常。 根據我對異常彈簧引導的理解，試圖說當我在項目的其他任何地方使用@ComponentScan(basePackages="packagePath")時，我無法在camel Route文件上使用默認注釋@Component ，因為它是一個MVC架構，我有控制器，服務和存儲庫，我不能忽視，請幫我解決這個問題。

Answer 1

問題是，RelaxedPropertyResolver已在春季啟動（2.0.0.RELEASE）的最新版本中刪除。 但是，最新的camel-spring-boot-starter模塊（寫入時為2.20.2）仍取決於缺少的RelaxedPropertyResolver。

要解決此問題，直到有新版本的Camel，您需要將spring-boot降級為1.5.10.RELEASE。
