通过Hibernate将webapp连接到docker mysql容器的延迟非常大

我正在尝试使用Hibernate、针对ApacheTomcat的XAMPP和mysql服务器将我在Windows上创建的web应用程序移植到Linux，使用Docker

完成以下步骤后，我的web.app的第一个功能是登录/注册表单：在Windows上，所有功能都可以正常工作，但使用容器时，延迟大约为几十分钟。。有时也会有500个http错误

docker run-d——名称mysql phpmyadmin-p 127.0.0.1:8686:80-p 127.0.0.1:3306:3306 grzesiekb/mysql phpmyadmin

docker run-d-p 8484:8080-p 8007:8009——名称tomcat8链接——链接mysql phpmyadmin:mysqlphp tomcat:8.0-jre8

然后部署在webapps/文件夹my warfile下

在我的hibernate.cfg.xml中，您可以看到它（我无法以可视方式粘贴它）：）

在my mysql容器my.cnf中有：

默认情况下，这个mysql容器只允许从localhost进行连接：为了允许从任何地方进行连接，我做了以下工作：

授予在上的所有特权。使用GRANT选项发送到由“密码”标识的“根”@“%”； 同花顺特权

然后我通过phpmyadmin导入了我的dql转储

描述您收到的结果：

巨大的延迟，与我不知道是哪个问题有关，并且以随机方式无法连接到mysql。没有日志。我的老师说可能是Docker网络的DNS问题

描述您期望的结果：

---

立即连接到数据库，就像在使用XAMPP的Windows中一样，您应该尽量使您的设置成为标准设置，以避免由于非标准做法而导致的错误

• 使用官方或至少流行的图像（数百万次拉取），而不是mysql phpmyadmin的100次拉取：
• 我不知道为什么要用主机端口和容器端口声明ip，如果没有必要，可能不这样做，只发布主机端口和容器端口，而不是ip

• 不要使用--link，因为它是，创建一个网桥网络并使用--network my bridge network运行每个容器

• 使用适用于此LTS版本的最新可用“HWE”内核将Ubuntu升级到最新的LTS版本（16.04.2）（您必须使用单独的命令升级内核，如下所述：

  sudo apt get install--install建议xserver-xorg-HWE-16.04

谢谢你的回答，Tristan。我尝试了这个新的mysql容器：docker run——命名一些mysql-e mysql\u ROOT\u PASSWORD=pass-p 3307:3306-d mysql然后这个是phpmyadmin:docker run：docker run——命名myadmin-d——链接一些mysql:mysql-p 8686:80 phpmyadmin/phpmyadmin我已经给了值“0.0.0.0”为了在mysql配置文件中绑定_地址，我创建了一个bridge docker网络，连接了tomcat和mysql容器；然后在hibernate.cfg.xml文件中，我指向：3306/at_db，用户为“root”，密码为“pass”。但问题仍然存在！我给了你4个建议，你遵循了前2个，你忽略了后2个。你正在接近，只是不要忽略任何。不要配置mysql配置，这个映像应该是预配置的。如果不清楚：不要忘了更新你的操作系统和内核，不要使用“-link”对于phpmyadmin，如果您在tomcat和mysql之间有一个“延迟”，那么您应该看到phpmyadmin和mysql之间有相同的延迟。
