If I use generated jooq Java pojo, I cannot use it...
# http4k

If I use generated jooq Java pojo, I cannot use it in the OpenApi spec. Is this expected?

@Riku what error do you get? There’s nothing in http4k that’d prevent that AFAIK. Most likely that’s a limitation in the json library, as they tend to be picky about how the code should look like.
r
e.g.
I have not had trouble with serialization otherwise. The lens seems to work. I was missing some examples though and when I added them, I ran into these errors.
Well I replaced them with data classes for now
s
That seems like a limitation on how we resolve field names using reflection :(
d
@Riku are the field names capitalised? If so see the faq https://www.http4k.org/guide/modules/json/. you can also write a custom FieldRetreival and plug it into the OpenApi generator.
r
no, they are not
d
Have you got an example of the Json as well?
r
[{"name":"8-12","category":"AGE_GROUP","createdAt":"2020-09-18T10:03:25.429646"},{"name":"Ballet","category":"DANCE_TYPE","createdAt":"2020-09-18T10:03:25.429646"},{"name":"Kid","category":"AGE_GROUP","createdAt":"2020-10-17T21:39:53.879043"},{"name":"Test","category":"DANCE_LEVEL","createdAt":"2020-10-18T10:39:40.855793"},{"name":"Choreography","category":"SPECIAL_GROUP","createdAt":"2020-10-18T10:40:06.172039"},{"name":"Theatre","category":"UNKNOWN","createdAt":"2020-10-18T10:40:43.99458"}]
That is goes with the CourseTags error above.
d
That doesn't match the class you posted above..
If we can get the generated code as well I can try to take a look in a bit.
r
sorry that json was the switched out data class. But it works the same except there is an id field.
Copy code

}
that is the generated code for course tag
d
Could you double check your meta block - the one you posted initially was using a different lens
r
ah not there is not id after all…
I am using Jackson and the lens for that was
Copy code
Body.auto<List<CourseTags>>().toLens()
Copy code
returning(OK, courseTagListOutLens to listOf(exampleTag))
d
If it's not a mistake, it doesnt look like our FieldRetreival works with java pojos. You can write a custom one and plug it in until we add it in the lib
r
Copy code
val exampleTag = CourseTags("Kids", CourseTagCategory.AGE_GROUP, LocalDateTime.now())
ok, it is not a big deal for me as I was only using the generated pojos in a few places. But thought I would raise a flag in case you are interested
d
Thanka for raising it. 🙃
@Riku JTLYK that I've just added support for JavaBeans now in the contract descriptors. Not releasing not, but it will be in 3.269.0 when that drops.

David is Feature as a service. You rise an issue less than 4 hours later, he already added the implementation....
