我有一个json文档:我需要提取CreateTime和CorrelationId两者结合并记录,示例json文档是belwo { “ MessageId”:“ a156155f-1767-43a5-a6c0-01381291a64a”, “ MessageVersion”:“ 1.0”, “ CreateTime”::“ 2018-07-26T17:59:47.6303585Z”, “ PublishTime”:“ 2018-07-26T17:59:47.6323632Z”, “ TenantId”:“ SF”, “ UserId”:“ jdoe”, “ CorrelationId”:“ 15125215215126”, “ MessageNamespace”:{ “ BusinessUnit”:“ csg-acs”, “产品”:“ dp”, “模块”:“提交帐单”, “ MessageType”:“经过帐单审查” }, “标题”:{}, “ SchemaName”:“ csg.acs.bill”, “ SchemaVersion”:“ 1.0”, “信息”: { “ BillId”:“ bill-9939” }, “主机”:{ “ MachineName”:“ JB97316-D”, “ IPAddress”:“ 172.20.24.37”, “ Region”:“ us”, “ ProcessName”:“发布者”, “ ProcessId”:15804, “ EbeSdkVersion”:“ .NET,Mitchell.Corp.EnterpriseBusinessEvents.Message,0.1.0-dev-00012”, “ OperatingSystemVersion”:“ Microsoft Windows NT 6.2.9200.0” } }
当前实现我有以下转换 1)转换--expression =#jsonPath(payload,'$。CreateTime')>:extractedJson 2)transformCorrId:transform --expression =#jsonPath(payload,'$。CorrelationId')>:extractedJson
3):extractedJson>日志
因此,在此实现中,日志上的输出看起来像两行 2018-09-20 18:12:43.755信息25880 --- [-L-1]日志接收器:15125215215126 2018-09-20 18:12:43.756信息25880 --- [-L-1]日志接收器:2018-07-26T17:59:47.6303585Z
但是,我们希望将correlationIdId和creationTime组合在一起(类似于逗号分隔),例如 15125215215126,2018-07-26T17:59:47.6303585Z在发送到日志接收器之前,但不确定如何使用转换进行合并,因为转换将从两个输入接收有效载荷变量。因此,需要有关spEL表达式的帮助
谢谢您的帮助。
