Spring (Grails) WebSocket 立即记录错误：SubProtocolWebSocketHandler - ms 后未收到消息

groovy
import org.springframework.messaging.handler.annotation.MessageMapping
import org.springframework.messaging.handler.annotation.SendTo
import org.springframework.stereotype.Controller
@Controller
class ErrorController {
    @MessageMapping("/error")
    @SendTo("/topic/errors")
    def recordError(String errorMessage) {
        // 记录错误到日志或数据库等
        println("记录错误：" + errorMessage)
        return "Error recorded: " + errorMessage
    }
}

groovy
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker
import org.springframework.web.socket.config.annotation.WebSocketConfigurer
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry
@EnableWebSocketMessageBroker
class WebSocketConfig implements WebSocketConfigurer {
    @Override
    void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(new ErrorController(), "/error").setAllowedOrigins("*")
    }
}

javascript
var socket = new WebSocket("ws://localhost:8080/error");
socket.onopen = function() {
    console.log("WebSocket连接已打开");
    var errorMessage = "发生了一个错误";
    socket.send(errorMessage);
};
socket.onmessage = function(event) {
    console.log("收到服务器的响应：" + event.data);
};
socket.onclose = function() {
    console.log("WebSocket连接已关闭");
};
