not-null requirement ignored for primitives in data classes #242
Description
When deserializing a data class with primitive types, the default value for that java primitive type is used instead of throwing an IllegalArgumentException or MissingKotlinParameterException.
Steps to reproduce
- Create new project using maven archetype - org.jetbrains.kotlin:kotlin-archetype-jvm
- Add dependency on jackson-module-kotlin - 2.9.7
- Run the following test class
import com.fasterxml.jackson.module.kotlin.jacksonObjectMapper import com.fasterxml.jackson.module.kotlin.readValue import org.junit.Test import java.lang.IllegalArgumentException import kotlin.test.assertNull data class NullIntValue(val value: Int?) data class NullDoubleValue(val value: Double?) data class NullLongValue(val value: Long?) data class NullBooleanValue(val value: Boolean?) data class IntValue(val value: Int) data class DoubleValue(val value: Double) data class LongValue(val value: Long) data class BooleanValue(val value: Boolean) class DeserializationTest { private val objectMapper = jacksonObjectMapper() @Test fun `test value is null - Boolean`(){ val value : NullBooleanValue = objectMapper.readValue("{}") assertNull(value.value) } @Test fun `test value is null - Double`(){ val value : NullDoubleValue = objectMapper.readValue("{}") assertNull(value.value) } @Test fun `test value is null - Int`(){ val value : NullIntValue = objectMapper.readValue("{}") assertNull(value.value) } @Test fun `test value is null - Long`(){ val value : NullLongValue = objectMapper.readValue("{}") assertNull(value.value) } @Test(expected = IllegalArgumentException::class) fun `test value throws - Boolean`(){ val value : BooleanValue = objectMapper.readValue("{}") assertNull(value.value) } @Test(expected = IllegalArgumentException::class) fun `test value throws - Double`(){ val value : DoubleValue = objectMapper.readValue("{}") assertNull(value.value) } @Test(expected = IllegalArgumentException::class) fun `test value throws - Int`(){ val value : IntValue = objectMapper.readValue("{}") assertNull(value.value) } @Test(expected = IllegalArgumentException::class) fun `test value throws - Long`(){ val value : LongValue = objectMapper.readValue("{}") assertNull(value.value) } }
