​

implementation("com.fasterxml.jackson.module:jackson-module-kotlin:2.14.2")
@Component
class LoginFilter() : AbstractGatewayFilterFactory() {
    private val objectMapper = jacksonObjectMapper()

    override fun apply(config: Any?): GatewayFilter {
        return GatewayFilter { exchange, chain ->
                    DataBufferUtils.join(exchange.request.body)
                        .map {
                            val bytes = ByteArray(it.readableByteCount())
                            it.read(bytes)
                            DataBufferUtils.release(it)
                            bytes
                        }.flatMap {
                           // request body data get
                           val loginRequest = objectMapper.readValue(inputStream, LoginRequest::class.java)
                        }
                }
}

data class LoginRequest @JsonCreator constructor(
    val loginId: String,
    val password: String,
)
