我正在使用Spring 4應用程序（不幸的是不是Spring Boot），我無法使Web套接字正常工作。有一個簡單的TextWebSocketHandler實現，我在/ws路徑註冊，和我做得到確認日誌：向現有的Spring應用程序添加網絡套接字支持
映射的URL路徑[/ WS]到類型 [類 org.springframework.web.socket的處理程序.server.support.WebSocketHttpRequestHandler]
...但我無法連接網絡瀏覽器中的地址。我已經試過這基於註解的配置：
@Slf4j
@Configuration
@EnableWebSocket
public class WebSocketConfiguration implements WebSocketConfigurer {
public static final String WEB_SOCKET_PATH = "/ws";
@Autowired
private WebSocketService handler;
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
log.info("Registering web socket handler {} at '{}'.", handler, WEB_SOCKET_PATH);
registry.addHandler(handler, WEB_SOCKET_PATH);
}
}
我可以證實，WebSocketService handler不爲空，實際上實現了WebSocketHandler接口。雖然配置者顯然被觸發，連接與"ws://localhost:8081/ws"導致錯誤：
WebSocket連接到 'WS：//本地主機：8081/WS' 失敗：錯誤時 WebSocket的握手：意外的響應代碼：404
錯誤{目標：網頁套接字，isTrusted：真，currentTarget當前：網頁套接字， 的EventPhase：2，氣泡：假的，或取消：假，defaultPrevented： 假，時間戳：1469616712980247，originalTarget：網頁套接字， explicitOriginalTarget：網頁套接字，NONE：0}
，我使用來測試網絡套接字機制的客戶端代碼是非常簡單的：
var ws = new WebSocket("ws://localhost:8081/ws");
ws.onerror = function(e) { console.log(e); }
ws.onopen = function() { console.log("Opened"); }
我甚至嘗試通過註冊XML配置的處理器，但是當我得到幾乎相同的日誌，它仍然不起作用。請注意，我使用幾乎默認配置的Jetty 9（通過Gretty Gradle插件）運行應用程序。
當通過春調試日誌去，我只能猜測，春促進HTTP請求到web套接字連接失敗：

已經通過官方文檔和示例看着，似乎在網絡插座配置非常標準。是否有我可能錯過的任何配置，或者我可能必須更改以在Spring中啓用Web套接字的配置？
我已經看到了大多數相關的問題，並沒有列出的解決方案爲我工作，真的。我的'@ Configuration'註釋組件被找到並觸發，Web套接字處理程序_seems被正確註冊，但我仍然在'/ ws'獲得404。它似乎從不嘗試將HTTP請求提升到web套接字會話中。 – JustACluelessNewbie
