Jackson Kotlin Module

If you are using Jackson you are likely to want to add com.fasterxml.jackson.module:jackson-module-kotlin dependency in order to allow it to deal with data classes with no default constructor or with Kotlin collections.

In addition to the dependency, you need to register it in Jackson ObjectMapper:

@SpringBootApplication
open class Application {

	@Bean
	open fun objectMapperBuilder(): Jackson2ObjectMapperBuilder
	    = Jackson2ObjectMapperBuilder().modulesToInstall(KotlinModule())

	// ...
}
