这是我第一次尝试在我的 Wildfly 服务器中设置数据源。我尝试按照我在 Google 上找到的一些教程进行操作，但它仍然不起作用。

我正在处理 Web 服务，但在部署 .war 文件时我总是遇到一些错误。

这是部署应用程序时的最新日志:

最佳答案

进入您的 Wildfly 控制台(类似于 localhost:9990)并编辑 Configuration->Container->EE->Default Bindings 部分。将默认数据源设置为某个有效数据源的 JNDI 名称。

我删除了默认的那个，只是将它指向我的主数据源，因为服务器只运行一个应用程序。

关于java - 使用 DataSource 的 Wildfly 配置，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22749570/
