spring - 弹簧网络套接字；处理程序没有适配器

Question

我一直在尝试设置一个简单的 WebSocketHandler 实现，但我遇到了这个javax.servlet.ServletException: No adapter for handler [turnip.gg.TurnipWebSocketHandler@5fdceca2]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler我无法解决的错误。

这是我的配置；

@Configuration
class WebSocket {
    @Autowired
    @Qualifier("TurnipWebSocket")
    private lateinit var handler: WebSocketHandler

    @Bean
    fun handlerMapping() = SimpleUrlHandlerMapping(mapOf("/socket" to handler), 1)

    @Bean
    fun handlerAdapter() = WebSocketHandlerAdapter()
}

这是我的简单 WebSocketHandler

@Component("TurnipWebSocket")
class TurnipWebSocketHandler : WebSocketHandler {
    override fun handle(session: WebSocketSession): Mono<Void> = session.receive()... // Does other stuff with it
}

提前致谢！
