Wildfly 数据源未连接到 MySql 数据库

【问题标题】：Wildfly datasource does not connect to MySql databaseWildfly 数据源未连接到 MySql 数据库
【发布时间】：2020-06-19 11:10:34
【问题描述】：

我对 Wildfly/JBoss 完全陌生，所以我不知道该怎么做，从昨天中午开始我就一直在处理这个问题。 我正在尝试使用 mysql-connector-java-8.0.20.jar 作为连接器，而我的 Wildfly 版本是 wildfly-19.0.0.Final。 所以服务器上的部署似乎工作正常，但是每当我尝试添加数据源并测试连接时，我都会收到此错误：

"WFLYJCA0040: failed to invoke operation: WFLYJCA0047: Connection is not valid"

日志/服务器抛出：

正如我所说，我是新人，所以请不要期望有太多关于 Wildfly 的现有知识。 感谢问候！

【问题讨论】：

  • 服务器时区无效。更新 MySQL 上的时区或将时区作为 JDBC URL 中的参数传递。
  • 根据堆栈跟踪：The server time zone value 'Mitteleurop?ische Sommerzeit' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specifc time zone value if you want to utilize time zone support.
  • 我在哪里可以更改设置？谷歌说，应该有一个 my.conf 文件，但我不知道在哪里找到它。

【解决方案1】：

解决方案 1：使用连接器上的数据库 url 传递时区

您的数据库 URL 应类似于 jdbc:mysql://ip_address:port/port?serverTimezone=UTC
您可以更改为您选择的时区

解决方案 2：更改 MySQL 配置文件

在 ubuntu 上，配置文件是 my.cnf。对于 ubuntu 18.04，文件的位置是 /etc/mysql/my.cnf
添加如下一行：
默认时区 = '+01:00'
设置为您的首选时区
重启你的 MySQL 服务器。

    【解决方案2】：

    是的，谢谢，解决方案 2 有效！
    在我的情况下，my.cnf 文件被称为“我的”，所以这有点令人困惑。不知道为什么这么叫。
    我在这个路径找到了文件： C:\ProgramData\MySQL\MySQL 服务器 8.0
