虽然 zyro 发起的 bug 修复带来了一些改进，但错误仍然没有完全消失。它仍然看起来像这样：

所以实际上只有错误的第二部分消失了......

=== 原始帖子 ===

我在 Tomcat 8.0.28 catalina.out 日志中发现了很多错误。我猜这是由我使用的 websocket 插件引起的。我在如下服务类中进行了实现：

def publishNewChart(def productId) {
        def linechart = chartService.getLinechart(Product.load(productId));

        brokerMessagingTemplate.convertAndSend("/topic/trade_chart/" + productId, linechart);
    }

在客户端以下：

$(function() {
        var socket = new SockJS("${createLink(uri: '/stomp')}");
        var client = Stomp.over(socket);

        client.connect({}, function() {

            client.subscribe("/topic/trade_chart/${product?.id}", function(message) {
                var messageJson = $.parseJSON(message.body);
                refreshPriceChart($.parseJSON(messageJson.data));
                brushed();     
            });
        });
    });

有没有人知道错误来自哪里以及如何处理它们？

提前感谢日志！
