fix: map Java Object to Kotlin Any

[allantodd]

The code generator uses Object instead of Any resulting in compiler warnings as described at https://github.com/querydsl/querydsl/issues/3740

Thanks, sorry I didn't get time to reply sooner.

Here's a more complete example of how we're using Any to store arbitrary nested metadata as JSON in Postgres. The problem is that basically Kotlin calls Object Any and it was missed in the mappings.

    @Convert(converter = MetadataConverter::class)
    @Column(columnDefinition = "jsonb")
    var metadata: Map<String, Any> = mutableMapOf()

where the converter is

import com.fasterxml.jackson.module.kotlin.jacksonObjectMapper
import com.fasterxml.jackson.module.kotlin.readValue
import jakarta.persistence.AttributeConverter

class MetadataConverter : AttributeConverter<Map<String, Any>, String> {

    private val objectMapper = jacksonObjectMapper()

    override fun convertToDatabaseColumn(attribute: Map<String, Any>?): String {
        return objectMapper.writeValueAsString(attribute ?: emptyMap<String, Any>())
    }

    override fun convertToEntityAttribute(dbData: String?): Map<String, Any> {
        return objectMapper.readValue(dbData ?: "{}")
    }
}

Well, if you keen, please update the example https://github.com/OpenFeign/querydsl/tree/master/querydsl-examples/querydsl-example-kotlin-codegen

All good if you can't, but amazing if you could

Ah, hadn't seen that module. Okay will take a look. Thanks
