这是与此问题

相关的问题

https://github.com/ging/fiware-cygnus/issues/6

我已经在docker上部署了物联网堆栈。这些是使用过的容器：

• 固件/猎户座：2.0.0
• ging / fiware-cygnus：latest

ging / fiware-cygnus：latest

当前图像 fiware / orion：2.0.0 正在发送标头，如下所示。

具体来说，标头“ Fiware-Servicepath” 与该行代码所期望的不匹配。 “ fiware-servicepath”，“ Fiware-ServicePath”，“ fiware-servicepath”

     

这会导致以下错误：

     

`2018-10-31 12：15：41,201错误[计时器驱动的进程线程1] oanifi.processors.ngsi.NGSIToMongo NGSIToMongo [id = 8f96c89d-850a-3578-b512-2b3f5f4fdacd] java .lang.NullPointerException

我认为是此行引起的

String fiwareServicePath = (flowFile.getAttribute("fiware-servicepath")==null) ? flowFile.getAttribute("Fiware-ServicePath"):flowFile.getAttribute("fiware-servicepath");
