SpringBoot應用程序啓動多次並從logstash斷開連接

Question

我有一個在docker上運行的springboot應用程序（Spring Boot v1.3.5.RELEASE），它使用./mvnw;

它「重新啓動」 1-2分鐘後，和第二開始後他們不發送任何日誌logstash ..

在第一次啓動，我們看到下面的日誌之後的第二

2016-07-27 08:54:29,616 DEBUG [background-preinit] logging: Logging Provider: org.jboss.logging.Slf4jLoggerProvider found via system property 

錯誤一個記錄提供商日誌缺少..

另一個觀察..看到第二次創業就是「0.899秒」這是不可能的..其實這似乎第二個是不是一個真正的開始，但logstash連接不見了。

這第二次啓動的原因是什麼？我應該在哪裏檢查和調查;

Answer 1

我發現了問題，細節在這裏; https://github.com/spring-cloud/spring-cloud-stream/issues/605

Answer 2

從documentation：

使用彈簧引導devtools會自動重啓 應用程序只要在classpath變化的文件。

您可以exclude resources或disable restarts。
