CanalClientException: java.io.IOException: end of stream when reading header
defined in com.xpand.starter.canal.config.CanalClientConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.xpand.starter.canal.client.CanalClient]: Factory method 'canalClient' threw exception; nested exception is com.alibaba.otter.canal.protocol.exception.CanalClientException: java.io.IOException: end of stream when reading header
经过检查是主机IP和端口错误。
解决办法：去canal的安装目录下，logs>>canal下的canal日志文件里面查找 IP和端口号
start the canal server[xx.xx.xx.xx():11111]，端口号为11111
在微服务的配置文件里面用上面的IP和端口号，问题解决
