问题描述
我正在将一个项目从 Wildfly 8.2.1.Final 迁移到更新的版本。主要目标是将 Hibernate 5 与 Java 8+ 一起使用，并在与 java 11 兼容的 Wildfly 版本上运行，以便以后迁移（因此问题出现在 java 8 上）。
我们选择了 Wildfly 24.0.1.Final (Hibernate 5.3.20.Final)，因为它是 jboss-migration-tool 帮助迁移standalone.xml 的最后一个版本（WF 25 删除了对遗留内容的支持，所以这将是手动迁移步骤）。
我们正在使用 Mariadb 10，最新版本的 Mysql 连接器 8。与 MySQL 连接器版本 5 或 mariadb jdbc 驱动程序相同的问题。
迁移非 XA 数据源（XA 数据源正常工作）时会出现此问题。在 EAR 部署后，Wildfly 在映射每个实体（请参阅日志）时一直警告我“未选择数据库”，然后在查询数据库时返回错误。
- 正如其他人所建议的那样，我检查了 connection-url 是否以正确的模式名称结尾。
- 测试与数据库的连接是可以的。
- 将数据源指定为 XA 时，它可以正常工作（请参阅standalone.xml 的摘录）
- 在 wildfly 8 上，XA 和非 XA 数据源都正常运行。
- 我尝试使用休眠属性 hibernate.default_schema 再次指定默认模式（voting_db）；我现在得到了 XA 和非 XA 数据源的错误，所以这似乎不是一个好主意（但是错误是不同的）。
- 我尝试降级到 2.0 版本的 persistence.XML
Wildfly 启动后，我收到以下警告：
WARN [org.jboss.as.connector.subsystems.datasources.AbstractDataSourceService$AS7DataSourceDeployer] IJ020020: Connection Properties for DataSource: 'java:jboss/datasources/votingDS' is empty, try to use driver-class: 'com.mysql.cj.jdbc.Driver' and connection-url: 'jdbc:mysql://localhost:3306/voting_db' to connect database
因此，我在通过 Wildfly 管理界面添加的数据源上检查了standalone.xml 语法，没有发现任何错误。下一条日志消息是通知数据源已正确绑定。不过，提示有问题吗？
我错过了什么？我已经尝试了几天，在网上搜索..
Standalone.xml 中的非 XA 数据源规范（简化）
这是产生错误的规范

日志
以下是日志的摘录。这向我提出了几个问题：
- 默认情况下是否启用二级缓存？还是因为某些实体被标记为 @cacheable 而被激活？
- hibernate.properties 文件有多重要？
