Subject [jira] [Commented] (LOG4J2-623) Better structure of Thread Context Map in JSONLayout
Date Mon, 12 May 2014 14:40:15 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13995116#comment-13995116
] 

Ralph Goers commented on LOG4J2-623:
------------------------------------

Gary, the correct syntax for a map in JSON is 

{code}
"mapName: {
 "MDC.B": "B.Value",
 "MDC.A": "A.Value"
}
{code}

not the way it was previously generated.  The Jackson docs specifically mention that you can
serialize and deserialize a Map with this syntax so I don't know why you would be having a
problem.

> Currently, the Thread Context Map looks like this in JSONLayout:
> {code:JavaScript|title=Current}
>  "Properties":[
>       {
>         "name":"UserName",
>         "value":"admin"
>       },
>       {
>         "name":"OrgName",
>         "value":"test"
>       } 
>     ] 
> {code}
> This does not properly make use of the JSON data format. Since the Thread Context Map
is a map, it should be represented as a JSON object. And why not name it "mdc" rather than
the quite vauge "Properties"?
> {code:JavaScript|title=Suggested}
>   "mdc": {
>     "UserName":"admin", 
>     "OrgName":"test"
>   }
> {code}
