这是我的bootstrap.properties文件：

注意：我在HTTP(端口80(连接上工作的应用程序没有任何问题，只有https(端口443(有此问题。
注意：此问题仅在Docker容器上解决，我在本地Machin(外部容器(上测试我的应用程序所有端口所有端口都没有任何问题。
这是应用程序服务器null指针异常
从我可以看出的情况下，此NPE发生是因为没有任何值集的HTTP标头将传递到按下。鉴于堆栈看起来像是Bad标头源于Open Liberty的Servlet 4实施。我已经打开了一个问题来跟踪这一点 - 您可以添加反馈吗？https://github.com/openliberty/open-liberty/issues/8474
至于您的应用程序为何在本地工作，我会检查是否正在使用HTTP/2实际上正在使用。如果您在Java 8上，则需要一个特定的环境才能通过ALPN通过SSL工作 - 请参阅https://www.ibm.com/support/knowledgecenter/knowledgecenter/en/sseqtp_liberty/com.ib.ib.ibm.m.websphere.wlp.doc/ae/cwlp_alpnsupport.html
