原因分析：

提示：我这里是websocket在断开连接时就会提示这个错误，但websocket连接的时候没问题，不太清楚怎么回事，如有大佬清楚，希望可以指教一下，谢谢

解决方案：

既然提示没有为它配置错误处理，那我们就为它配置一下错误处理

	/**
     * 配置错误信息处理
     * @param session
     * @param t
     */
	@OnError
    public void onError(Session session, Throwable t) {
    	//什么都不想打印都去掉就好了
        log.info("【websocket消息】出现未知错误 ");
        //打印错误信息，如果你不想打印错误信息，去掉就好了
        //这里打印的也是  java.io.EOFException: null
        t.printStackTrace();
    }
