Document ID as UUID

See original GitHub issue

Hello,

quick question, the documentation is a bit confusing on that part :

The @Id annotation needs to be present because every document in Couchbase needs a unique key. This key needs to be any string with a length of maximum 250 characters. Feel free to use whatever fits your use case, be it a UUID, an email address or anything else.

In case of UUID, the @Id has to be a stringified UUID ?

I’m asking because I tried to set a document Id as an UUID :

  • the write path is working well, the UUID is converted to a String
  • I’m facing this exception with the read path :
@Document
data class TestUUID(
    @field:Id
    val id: UUID,

    @field:Field
    val test: String
)

Caused by: java.lang.ClassCastException: class java.lang.String cannot be cast to class java.util.UUID (java.lang.String and java.util.UUID are in module java.base of loader 'bootstrap')

The issue is that the id for CouchbaseDocument is a String. I’m going to change it to Object and this should solve the problem.

btw - if you have a field named “id”, it doesn’t need the @Id annotation.
