提供下完整的错误额。
已经解决了，我是使用spring的kafka模版发送消息的，每次都新建了一个producer，没有使用到单例创建producer，导致kafka报了异常，阻止新的producer继续创建。kafka抛异常的源码：
private KafkaProducer(ProducerConfig config, Serializer<K> keySerializer, Serializer<V> valueSerializer) { try { log.trace("Starting the Kafka producer"); .... } catch (Throwable t) { // call close methods if internal objects are already constructed this is to prevent resource leak. see KAFKA-2121 close(0, TimeUnit.MILLISECONDS, true); // now propagate the exception throw new KafkaException("Failed to construct kafka producer", t); }ok，解决就好。
最后是怎么解决的呢
博主你好! 我也遇到这样的问题,我想歘构建2个不同的producer该怎么解决?
你提个新问题吧，描述一下你的情况。
1.博主 你好!我用springboot框架,创建2个不同地址的producer,只有一个地址的生产者被创建,而另一个确没有创建,一直报这个错误:Closing the Kafka producer with timeoutMillis = 0,Failed to construct kafka producer;这个问题有解决的思路吗?谢谢您!
博主,没有及时回复你,不好意思哈!

你可以参考下这个例子来解决你的问题。
你提供的信息太少了，如果还没解决，你发起一个新问题，把关键代码带上。
