杨老师好，您这份微服务课程中，没有涉及到分布式事务，什么时候会有这样的课程，或者有没有推荐的文章？

波波老师您好，我请求http://localhost:8080/s2g-zuul-mobile/admin/filterLoader.jsp没有任何响应是怎么回事QAQ。。。

老师，将cat去掉后，可以启动了，但访问http://localhost:8080/s2g-zuul-mobile/admin/filterLoader.jsp时页面是空白的，不知道为什么，请老师指点下，谢谢

出现下面错误是什么原因，麻烦老师知道一下 2020-05-05 22:13:43,857 [http-nio-8080-exec-3] ERROR io.spring2go.zuul.servlet.AsyncZuulListener- Access http://localhost:8080/s2g-zuul-mobile/ timeout in AsyncServlet. 2020-05-05 22:14:12,055 [ZuulFilterPoller] ERROR com.zaxxer.hikari.HikariPool- Timeout of 1000ms encountered waiting for connection. 2020-05-05 22:14:43,064 [ZuulFilterPoller] ERROR com.zaxxer.hikari.HikariPool- Timeout of 1000ms encountered waiting for connection. 2020-05-05 22:15:14,074 [ZuulFilterPoller] ERROR com.zaxxer.hikari.HikariPool- Timeout of 1000ms encountered waiting for connection. 2020-05-05 22:15:45,082 [ZuulFilterPoller] ERROR com.zaxxer.hikari.HikariPool- Timeout of 1000ms encountered waiting for connection. 2020-05-05 22:16:16,092 [ZuulFilterPoller] ERROR com.zaxxer.hikari.HikariPool- Timeout of 1000ms encountered waiting for connection. 2020-05-05 22:16:47,106 [ZuulFilterPoller] ERROR com.zaxxer.hikari.HikariPool- Timeout of 1000ms encountered waiting for connection. 2020-05-05 22:17:18,113 [ZuulFilterPoller] ERROR com.zaxxer.hikari.HikariPool- Timeout of 1000ms encountered waiting for connection.

我这边foundation-service依赖的 jar包是存在的，但是一直报下面错误 java.lang.NoSuchMethodError: org.unidal.lookup.ContainerLoader.getDefaultContainer()Lorg/codehaus/plexus/PlexusContainer; at com.dianping.cat.Cat.initialize(Cat.java:178) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.checkAndInitialize(Cat.java:75) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.getProducer(Cat.java:157) ~[cat-client-3.0.0.jar:na] at io.spring2go.zuul.filters.ZuulFilterPoller$1.run(ZuulFilterPoller.java:94) ~[s2g-zuul-core-1.0.0.jar:na]

老师，我这边一直下不下来cat-client.jar,然后自己去别的地方找了个，编译就没问题了。但是启动后，过会就报这个错误 信息: Server startup in 4724 ms 2019-12-07 16:55:55,535 [ZuulFilterPoller] ERROR io.spring2go.zuul.filters.ZuulFilterPoller- ZuulFilterPoller run error! java.lang.ExceptionInInitializerError: null at com.dianping.cat.message.internal.DefaultMessageManager.<init>(DefaultMessageManager.java:45) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageManager.<clinit>(DefaultMessageManager.java:52) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageProducer.<init>(DefaultMessageProducer.java:33) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageProducer.<clinit>(DefaultMessageProducer.java:37) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.initializeInternal(Cat.java:311) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.checkAndInitialize(Cat.java:72) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.getProducer(Cat.java:211) ~[cat-client-3.0.0.jar:na] at io.spring2go.zuul.filters.ZuulFilterPoller$1.run(ZuulFilterPoller.java:94) ~[s2g-zuul-core-1.0.0.jar:na] Caused by: java.lang.RuntimeException: Error when get cat router service, please contact cat support team for help! at com.dianping.cat.configuration.ApplicationEnvironment.loadClientConfig(ApplicationEnvironment.java:151) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.configuration.DefaultClientConfigService.<init>(DefaultClientConfigService.java:72) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.configuration.DefaultClientConfigService.<clinit>(DefaultClientConfigService.java:52) ~[cat-client-3.0.0.jar:na] ... 8 common frames omitted Caused by: java.net.SocketTimeoutException: connect timed out 一直卡在这检查了好久。暂时没有头绪。是我下的jar的问题还是啥问题。感觉我都按照老师的都做了，就是jar一直下不来，如果是jar的问题的话，老师可以给我一个下载方式么？

波波老师，数据库连接正常。但是，启动还是报如下错误： 2019-11-16 23:52:21,877 [ZuulFilterPoller] ERROR io.spring2go.zuul.filters.ZuulFilterPoller- ZuulFilterPoller run error! java.lang.ExceptionInInitializerError: null at com.dianping.cat.message.internal.DefaultMessageManager.<init>(DefaultMessageManager.java:45) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageManager.<clinit>(DefaultMessageManager.java:52) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageProducer.<init>(DefaultMessageProducer.java:33) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageProducer.<clinit>(DefaultMessageProducer.java:37) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.initializeInternal(Cat.java:311) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.checkAndInitialize(Cat.java:72) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.getProducer(Cat.java:211) ~[cat-client-3.0.0.jar:na] at io.spring2go.zuul.filters.ZuulFilterPoller$1.run(ZuulFilterPoller.java:94) ~[s2g-zuul-core-1.0.0.jar:na]

波波老师，请教一个问题：如何配置连接MySQL8.0数据,我偿试了好多方法都不成功。如下错误是数据罪连接的问题？还是jar版本的不匹配的问题？ 数据连接试了如下二个配置: zuul.data-source.class-name=com.mysql.cj.jdbc.Driver zuul.data-source.url=jdbc:mysql://localhost/clientdb?serverTimezone=UTC 或者 zuul.data-source.url=jdbc:mysql://localhost:3306/clientdb?characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true&allowPublicKeyRetrieval=true 如报如下错误: 2019-11-16 22:08:15,435 [ZuulFilterPoller] ERROR io.spring2go.zuul.filters.ZuulFilterPoller- ZuulFilterPoller run error! java.lang.ExceptionInInitializerError: null at com.dianping.cat.message.internal.DefaultMessageManager.<init>(DefaultMessageManager.java:45) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageManager.<clinit>(DefaultMessageManager.java:52) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageProducer.<init>(DefaultMessageProducer.java:33) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.message.internal.DefaultMessageProducer.<clinit>(DefaultMessageProducer.java:37) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.initializeInternal(Cat.java:311) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.checkAndInitialize(Cat.java:72) ~[cat-client-3.0.0.jar:na] at com.dianping.cat.Cat.getProducer(Cat.java:211) ~[cat-client-3.0.0.jar:na] at io.spring2go.zuul.filters.ZuulFilterPoller$1.run(ZuulFilterPoller.java:94) ~[s2g-zuul-core-1.0.0.jar:na]
