How can I customize date time JSON encoder output?

[Kazuo Koga]

I created a new app with lein template.

% lein new luminus myapp +reitit +swagger +service 

I would like to customize application/json output string of java-time/offset-date-time object.

default output is "2019-08-18T00:36:03.841+09:00"

and I want to output like "2019/8/18 00:36:03"

How can I?

I found file in template: src/clj/myapp/middleware/formats.clj

but I couldn't get a way.

I'm glad to appreciate any help.

Thank you,

Hi,

Sorry for the late reply. The easiest way would be to encode the data as json explictly in the handler using Cheshire, and you could specify a custom encoder for dates that uses the desired format https://github.com/dakrone/cheshire#custom-encoders

You can achieve that using something like (.format (java.text,SimpleDateFormat. "yyyy/M/dd HH:mm:ss") (java.util.Date.))
