贴system-config.properties出来看看

[dede8385]

我也碰到这样的问题，system-config.properties 配置如下：

Zookeeper list

kafka.zk.list=192.169.0.61:2181,192.169.0.62:2181,192.169.0.63:2181

zk limit

kafka.zk.limit.size=3

AnotherKafkaMonitor WebUI Port

kafka.eagel.webui.port=8080

Alarm Email Notice Configuration

anotherkafkamonitor.mail.enable=true
anotherkafkamonitor.mail.username=[email protected]
anotherkafkamonitor.mail.password=123456
anotherkafkamonitor.mail.server.host=mail.gyj.com
anotherkafkamonitor.mail.server.port=25

Alarm Mobile Notice Configuration

anotherkafkamonitor.mobile.enable=false
anotherkafkamonitor.mobile.username=xxx
anotherkafkamonitor.mobile.password=xxx

文本的排版有问题，再上传个图片吧！

[triffic-tang]

请替换ZkClient-0.10试试，ZkClient-0.10，若还是不行，请告知。

[triffic-tang]

@jiajie999 @dede8385

[dede8385]

替换了还是不行。jdk 有要求吗？
是不是我们使用的版本太高了，我的是1.8.0_144的，zk的版本也是3.4.11。
建议用到什么版本？

[triffic-tang]

@dede8385 JDK1.8没有本地测过，我有时间本地先测试一下，然后再告知。

[dede8385]

OK，建立测试一下目前主流的配置。
JDK: 1.8.0_XXX
ZK: 3.4.1X
TOMCAT:8.X.X

[dede8385]

简单的看了下你的源码，我这边的问题是：
ZKPoolUtils.http-nio-8080-exec-2 - INFO - Initialization ZkClient pool size [0]
ZKPoolUtils 类中的 poolSize 读取配置文件的没有生效，值为0.
