CEP质子关键不在 Map 中，原因是：关键不在 Map 中

我试图将Proton与Orion集成，但是当Orion向Proton发送事件时，我总是得到同样的错误：

com.ibm.hrl.proton.webapp.providers.EventJSONMessageReader readFrom SEVERE：无法解析json事件org.apache.wink.json4j.JSONException：键[Name]不在 Map 中，原因：键[Name]是不在 Map 上

我已经查看了属性名称，它们没问题 .

见下面Cygnus看到的attrNames（已与Orion集成）

我还附加了json导出项目的一部分 .

你能救我一下吗？

先谢谢

    CEP Proactive Technology Online（Proton）和Orion之间的集成使用xml格式（而不是json） .

    猎户座的帖子需要包含

    Content-Type: application/xml

    CEP Proactive Technology Online的user guide中的附录描述了如何在Orion和Proton之间进行集成 .

    请注意，CEP事件定义必须具有一些属性，并且CEP输入事件的名称必须是[entity type] ContextUpdate，如user guide附录中所述

    确保导出更新的定义并停止并启动CEP以使其与更新的定义一起运行

    我在Docker实例中遇到了同样的问题 . 尽管事件定义遵循用户指南附录A中描述的规则，但日志会不断报告：

    INFO: started event message body reader
Oct 26, 2015 1:25:36 PM com.ibm.hrl.proton.webapp.providers.EventXmlNgsiMessageReader readFrom
SEVERE: Could not parse XML NGSI event java.lang.NullPointerException, reason: null
last attribute name: null last value: null
Oct 26, 2015 1:25:36 PM com.ibm.hrl.proton.webapp.providers.EventXmlNgsiMessageReader readFrom
INFO: finished event message body reader
Oct 26, 2015 1:25:36 PM com.ibm.hrl.proton.webapp.resources.EventResource submitNewEvent
INFO: starting submitNewEvent
Oct 26, 2015 1:25:36 PM com.ibm.hrl.proton.webapp.resources.EventResource submitNewEvent
SEVERE: Could not send event, reason: java.lang.NullPointerException, message: null

    我决定尝试使用artifacts文件夹中的.war文件（编辑Dockerfile），而不是Dockerfile（原始文件）中使用的文件 . 现在一切正常，无需更改事件定义 .

    通过比较日志文件，我注意到原始Docker实例的catalina.out中缺少以下部分：

    com.ibm.hrl.proton.server.executor.PropertiesParser loadProperties
INFO: Properties are : 
metadatFile =/tmp/defs/DoSAttack.json 
inputPortNumber =3002 
outputPortNumber =3302

    这里是Dockerfile中的更改：

    #WORKDIR /root/Proton/mvn-repo/com/ibm/hrl/proton/AuthoringTool/0.0.1
#RUN cp *war /var/lib/tomcat7/webapps/AuthoringTool.war
#WORKDIR /root/Proton/mvn-repo/com/ibm/hrl/proton/AuthoringToolWebServer/0.0.1
