Context: I am using Kotlin with Micronaut and for this project I will not add Spring dependencies.
I created successfully a Hello Word enpoint and I can post to it from Postman. The issue started when I evolulated the data to have birthday (java.time.LocalDate).
Copied from Postman
curl --location --request POST 'localhost:8080/accountholders' --header 'Content-Type: application/json' --data-raw '{
"name": "Jimis",
"age":42,
"birthDate":"1978-04-14",
"category":"'\''Student'\''"
}'
Resulted in
{
"message": "Required argument [AccountHolder accountHolder] not specified",
"path": "/accountHolder",
"_links": {
"self": {
"href": "/accountholders",
"templated": false
}
}
}

The whole project git hub (the error in the branch date_issue, not in the master)
You should annotate the method parameter with @Body
:
import io.micronaut.http.annotation.*
// ...
@Post
@Consumes(MediaType.APPLICATION_JSON)
fun addAccountHolder(@Body accountHolder: AccountHolder): AccountHolder {
return accountHolderService.addAccountHolder(accountHolder)
}
