我有以下网络套接字配置
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
private static final long heartbeatTime = 60000L; // 1 minute
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint(Constants.BASE_NOTI).withSockJS().setInterceptors(new HttpSessionHandshakeInterceptor()).setHeartbeatTime(heartbeatTime).setSessionCookieNeeded(true);
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
.....
}
@Override
public void configureClientOutboundChannel(ChannelRegistration registration) {
registration.taskExecutor().corePoolSize(2).maxPoolSize(3);
}
@Override
public void configureWebSocketTransport(WebSocketTransportRegistration registration) {
registration.setMessageSizeLimit(128 * 1024).setSendTimeLimit(15 * 1000).setSendBufferSizeLimit(512 * 1024);
}
}
我不时看到的例外是

答案 0 :(得分：0)
从这个Software caused connection abort: socket write error判断，看起来服务器正在尝试写入套接字，但连接已经关闭。
我能想到的一些原因：
至少在这种情况下，这种情况发生在HTTP升级阶段，这让我想问：你有这些案例的浏览器网络/控制台日志吗？也许客户端不支持HTTP升级并关闭连接？
无论如何，我强烈建议您configure your Tomcat server to use the NIO connector。
