Is there a way to validate JSON body (from a request) to ensure the required fields are there, just like form validation?

I'm using play-java, version 2.5

Thanks

Hello, Raunak!

Or course, there is: https://www.playframework.com/documentation/2.5.x/ScalaJsonCombinators#Validation-with-Reads

Oh, sorry, I've noticed that you talk of Play Java only after the answer had been sent.

Yes, looking to do it in Java. Its been possible to do so in scala as far as I can remember. Though, I think its possible to do it in Java in 2.5 as well, just not sure how, yet! :)

This is maybe more of a Jackson question than a Play one. Maybe you can try posting on their mailing list.

Raunak,

How did you finally implement this ?

After doing some research, i had two options available. Depending on your use case, you can pick either, as for me, I went with option 1.

1. Use BeanValidation library

2. Use @JsonProperty(required=true), which is similar to @Constraints.Required in Play.
