How can I directly output a message object into a JSON structure?

[youngledo]

For example, this method supports messages passed in to an "Object" object, but the actual output is just a simple string.

Therefore, to achieve this, I need to convert to a "JSON" string in advance before I can output the JSON structure I want.

And there are also warning prompts.

This is the output result:

Note that "JsonTemplateLayout" is not what I want, because it requires the JSON template to be defined in advance.

@youngledo, do you want a custom Object to be encoded in JSON along with the rest of the JSON-encoded LogEvent?

If so, you can achieve this by combining JSON Template Layout (JTL) with following logging schemes:

1. You can pass a MapMessage
2. You can wrap your object in an ObjectMessage

If you wrap your Object in an ObjectMessage, and if your Object is either a Map, Collection, Number, Boolean, CharSequence, JTL will take care of JSON encoding for you. Otherwise, your custom Object either need to a) implement the StringBuilderFormattable interface to encode the object in JSON, or b) do the same in the object's toString() method.

If none of the above work for you, please provide an example of your use case with code that we can reproduce the issue on our side.
