Creating custom ErrorWebExceptionHandler fails

Question

I am trying to create my own ErrorWebExceptionHandler in Spring Boot 2 by extending the default one but my application fails to start with the following message:

Answer 1

I just did this as well, and after looking at springs implementation I just added the components to the constructor.

@Component
@Order(-2)
class GlobalErrorWebExceptionHandler(
        errorAttributes: ErrorAttributes,
        resourceProperties: ResourceProperties,
        applicationContext: ApplicationContext,
        viewResolvers: ObjectProvider,
        serverCodecConfigurer: ServerCodecConfigurer
) : AbstractErrorWebExceptionHandler(
        errorAttributes,
        resourceProperties,
        applicationContext
) {
    private val logger = LogFactory.getLog(GlobalErrorWebExceptionHandler::class.java)!!

    init {
        setViewResolvers(viewResolvers.orderedStream().collect(Collectors.toList()))
        setMessageWriters(serverCodecConfigurer.writers)
        setMessageReaders(serverCodecConfigurer.readers)
    }

    override fun getRoutingFunction(errorAttributes: ErrorAttributes) = RouterFunctions.route(RequestPredicates.all(), HandlerFunction { request ->
        val ex = getError(request)
        logger.error(ex.message)

        ServerResponse.ok().build()
    })
}
