Question

我正在开发一个接收HL7消息并返回HL7 ACK的简单应用程序。我使用此处的示例开始实现：Acknowledgement example in HL7 DataWeave Examples section

在测试示例代码时，如果HL7中没有错误，则ACK很好，但是当解析HL7时出现任何错误时，ERR段不包含任何字段：

MSH|^~\'|LABADT|MCM|ADT1|MCM|198808181126|SECURITY|ACK^A01^ACK|MSG00001-|P|2.6
MSA|AE|MSG00001-
ERR

在日志中还可以找到以下警告：

WARN  2018-03-28 10:01:13,110 [[hl7ack].HTTP_Listener_Configuration.worker.01] 
com.mulesoft.flatfile.1.3.0.lib.schema.hl7.HL7SchemaWriter: missing required value for component ERR-03: 'HL7 Error Code' for segment ERR at index 2
WARN  2018-03-28 10:01:13,110 [[hl7ack].HTTP_Listener_Configuration.worker.01] 
com.mulesoft.flatfile.1.3.0.lib.schema.hl7.HL7SchemaWriter: missing required value for component ERR-04: 'Severity' for segment ERR at index 2

似乎HL7 EDI转换器组件生成的ERR段的架构与默认的HL7架构不匹配。有什么我做错了吗？我尝试在HL7配置中包含ACK模式，但遇到了同样的问题。

以下是Mule应用程序代码（与示例相同）：

HL7 EDI组件生成的ACK与HL7架构不匹配。具体而言，ERR结构不包含ERR-01列表。我使用以下转换（代替上面的简单转换）来生成正确的确认。

%dw 1.0
%output application/java
---
{
    Id: "ACK",
    Name: "ACK",
    MSH: payload.ACK.MSH,
    Data: {
        ACK: {
            MSH: payload.ACK.MSH,
            MSA: payload.ACK.MSA,
            ERR: [{
                ERR-01: (payload.ACK.ERR map ((eRR , indexOfERR) -> {
                    ERR-01-01: eRR.ERR-01-01,
                    ERR-01-02: eRR.ERR-01-02,
                    ERR-01-03: eRR.ERR-01-03,
                    ERR-01-04-01: eRR.ERR-01-04-01,
                    ERR-01-04-02: eRR.ERR-01-04-02,
                    ERR-01-04-03: eRR.ERR-01-04-03
                }))
            }]
        }
    }
}
