@ChA0S-f4me Is toMap2 function something that you wrote?

@ChA0S-f4me Is toMap2 function something that you wrote?

Sure

@ChA0S-f4me I use the following example code to solve it

fun <ID : Comparable<ID>> Entity<ID>.toMap(): Map<String, Any?> {
    val map = this::class.declaredMemberProperties.associate {
        it.name to it.apply { isAccessible = true }.call(this)
    }.toMutableMap()
    map["id"] = id.value;
    return map
}

hope that helps to you。

@xiaoliang-cn looks like you are trying to serialize UserTable with gson. Can you show the complete stacktrace to confirm it?

[zxcqirara]

I started using jackson instead of GSON, after that it started working normally
