【问题讨论】：
我有类似的问题。清理了这很简单。您在服务器配置（检查standalone.xml）和 Przychodnia-ds.xml 中注册了两次数据源。您只想选择一个地方吗？
【讨论】：
【参考方案2】：在您的../wildfly-X.X.X/standalone/configuration/standalone.xml 中，您将看到以下内容：
<deployments>
<deployment name="your_file.war" runtime-name="your_file.war">
<fs-archive path=".../your_file.war"/>
</deployment>
...
</deployments>
这会导致 DuplicateServiceException。只需将其删除。
【讨论】：
这对我来说非常有效。你能解释一下，为什么上面的行会导致 DuplicateServiceException。 编辑standalone.xml后别忘了重启服务器。【参考方案3】：
我认为这里的问题是关于数据源条目的重复
