How to handle java.time.Instance, LocalDateTime, etc., as render-able output?

[bkuntzelman]

For example, any type/class I have that references LocalDateTime gives an error message:

"no suitable method found for writeUserContent(java.time.LocalDateTime)"

How do we add our own "custom renderers" that don't already have support?

Am I completely missing how to do this in the documentation?

I'm running under Spring Boot 3.3.10 and JTE 3.1.16.

Thanks!

Somewhere you're going to want to use a DateTimeFormatter to turn your value into a String.

The localization page in the documentation has some ideas that could work for this too.

You can read more info here.

Since toString() isn't automatically called like other templating frameworks due to security concerns, you will have to output your data down to primitive types yourself.

For my case, I'm using Kotlin, so I just ended up implementing extension methods on data types I'm interested in. In Java, you probably have to create and import static utility methods instead.

Okay, thanks. Once I dug into it a bit deeper, I expected that's what was necessary. Thanks for confirming I wasn't missing some documentation.
