JsonTemplateLayout eventTemplateUri from spring cloud config

[paulmarcelinbejan]

I have configured my application to log as JSON using log4j2 configuration:

Configuration:

  status: warn

  Appenders:
    Console:
      name: CONSOLE
      target: SYSTEM_OUT
      JsonTemplateLayout:
        eventTemplateUri: "classpath:log4j2/templates/jsonLayout.json"

  Loggers:
    Root:
      level: INFO
      AppenderRef:
        - ref: CONSOLE

at the moment I'm using a file in the classpath (as configured on property Configuration.Appenders.Console.JsonTemplateLayout.eventTemplateUri), but since I have a cloud config server, I would like to move that file into the cloud config server to be centralized and used by all microservices.

is there a feature to retrieve the file from url ? like I'm doing for logging.config since I'm using

logging.config: http://config-provider:8888/config/coanda-airlines-config-provider/application-config-log-json.yaml

I embed mine into the logging configuration file:

  <Appenders>
    <Console name="log4j" target="SYSTEM_OUT">
        <JsonTemplateLayout locationInfoEnabled="true">
            <eventTemplate><![CDATA[
{
  "@timestamp": {
    "$resolver": "timestamp",
    "pattern": {
      "format": "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'",
      "timeZone": "UTC"
    }
     ...
     ...
  }
}]]></eventTemplate>
        </JsonTemplateLayout>
    </Console>
  </Appenders>

The solution proposed by Ralph is the only one currently available, since JTL only handles file: and classpath: URIs.

I have opened #2537 to fix this.
