【问题描述】:
我的 Mule 流程中有一个消息丰富器,如下所示:
<set-variable doc:name="Variable" value="#[payload['MeterUID']]" variableName="#['theKey']"/>
<enricher target="#[payload]" doc:name="Message Enricher">
<mongo:find-objects-using-query-map config-ref="Mongo_DB1" collection="meterentity" doc:name="Mongo DB">
<mongo:query-attributes>
<mongo:query-attribute key="_id">#[theKey]</mongo:query-attribute>
</mongo:query-attributes>
<mongo:fields>
<mongo:field>IpAddress</mongo:field>
<mongo:field>LastSetTime</mongo:field>
<mongo:field>LastReadGsmData</mongo:field>
</mongo:fields>
</mongo:find-objects-using-query-map>
这是消息丰富器从我的入站端点收到的有效负载:
{TimeStamp=2013-12-16 08:48:33,270, MeterUID=4B414D000000011613CF, SignalStrengthIndication=15, CellID=4938, LocationAreaCode=280, MobileCountryCode=238, MobileNetworkCode=1}
在 Mongo-collection to json 中,我的有效载荷如下所示:
[ { "_id" : "4B414D000000011613CC" , "IpAddress" : "10.12.189.12" , "LastSetTime" : { "$date" : "2014-03-11T14:40:36.987Z"} , "LastReadGsmData" : { "$date" : "2014-03-11T14:40:47.253Z"}}]
这对我来说似乎是错误的。首先,我的第一个有效载荷去哪儿了? 其次,当流尝试插入我的 mongodb 时,我得到了这个错误:
Exception stack is:
1. BasicBSONList can only work with numeric keys, not: [_id] (java.lang.IllegalArgumentException)
org.bson.types.BasicBSONList:161 (null)
2. Failed to invoke insertObject. Message payload is of type: String
我怎样才能做到这一点? 我对骡子还是很陌生,所以我希望你们能在这里帮助我。
我的整个流程:

我想读取一个 CSV 文件,将其拆分为更小的消息,用来自 MongoDB 的数据丰富每条消息,最后将每条消息插入另一个 MongoDB。
