SpringBoot应用程序多次启动，并与Logstash断开连接 [英] SpringBoot app starts multiple times and disconnects from logstash

问题描述

我有一个使用./mvnw在docker上运行的springboot应用程序(Spring Boot v1.3.5.RELEASE);

I have an springboot application (Spring Boot v1.3.5.RELEASE) that is run on docker with ./mvnw;

它会在1-2分钟后重新启动"，并且在第二次启动后，它们不会将任何日志发送到logstash.

it "restarts" after 1-2 minutes and after second start they don't send any log to logstash..

首先，我们在下面的日志中看到

in first start we see below log

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

在第二个日志记录提供程序日志丢失后出现

bug.

bug after the second one logging provider log is missing..

另一观察..看到第二个起点仅仅是"0.899秒"，这是不可能的..实际上，似乎第二个起点不是真正的起点，但logstash连接已消失..

another observation.. see second start is just "0.899 seconds" which is not possible.. Actually it seems second one is not a real start but logstash connection is gone..

第二次开始的原因可能是什么?我应该在哪里检查和调查；

What may be the reason for this second start? Where should I check and investigate;
