我试图在Java中创建简单的Web套接字
import java.io.IOException;
import java.util.List;
import java.util.concurrent.CopyOnWriteArrayList;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.config.annotation.EnableWebSocket;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;
import org.springframework.web.socket.handler.TextWebSocketHandler;
@Configuration
@EnableWebSocket
public class webServiceConfig implements WebSocketConfigurer{
// server site end point as /senderrorlog
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry regestry) {
regestry.addHandler(new errorloghandler(), "/sendErrorLog").withSockJS();
}
class errorloghandler extends TextWebSocketHandler {
private List<WebSocketSession> sessions=new CopyOnWriteArrayList<WebSocketSession>();
@Override
public void afterConnectionEstablished(WebSocketSession session) throws Exception {
sessions.add(session);
}
@Override
protected void handleTextMessage(WebSocketSession session, TextMessage message) {
for(WebSocketSession s:sessions) {
try {
s.sendMessage(message);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
}
但是我一直在跟踪有关webSocketScopeConfigurer的错误，在此编程中可能会出错吗？您能告诉我其他代码仅仅是服务器和jsp吗，但是在此错误中却出现了问题，因为我跟随该站点创建名称为webSocketScopeConfigurer的
