延迟 Mirth 消息传递

Question

I am interfacing with a system which schedules appointments. The destination system does not allow appointments to be scheduled more than 30 days in advance, but the source system may send the appointment at any time (frequently beyond 30 days). How can I delay the delivery of the message till it is within the 30d window?

Answer 1

Create two channels. Have the first write the file to disk and set the "lastWriteTime" to the date you would like the message to be delivered. The second channel should read from this directory and use the "Check File Time" option to filter only those messages with historical dates.

Channel 1 destination 1:

Transformer Javascript:

    channelMap.put('deliverAfter', msg['SCH']['SCH.11']['SCH.11.1'].toString());

Destination Settings:

Connector Type: Javascript Writer

    var deliverAfter = DateUtil.getDate('yyyyMMddHHmm', $('deliverAfter'));
    var path = 'c:/data/queue/' + connectorMessage.getMessageId();
    org.apache.commons.io.FileUtils.writeStringToFile(new java.io.File(path), connectorMessage.getEncodedData(), 'UTF-8');
    java.nio.file.Files.setLastModifiedTime(java.nio.file.Paths.get(path), java.nio.file.attribute.FileTime.fromMillis(deliverAfter.getTime()));

Channel 2:

Source reader settings:

Path: c:/data/queue/
After Processing Action: Delete
Check File Age: Yes
File age (ms): 1000
Encoding: UTF-8

Answer 2

To avoid queuing messages to meet the delay threshold expected at the destination, I would do a JavaScript filter on the source connector of the source system to only fetch appointments that the destination considers due. For further assistance, you can share a template of a source system message sample (arbitrary values not real data, I am only interested in the place holders).
