From your log trace, it says: Unable to get managed connection for java:jboss/EmirDS
从您的日志跟踪中，它说：无法获得 java:jboss/EmirDS 的托管连接
I suspect you didn't configure EmirDS as datasource at your JBoss. Here is how you can check using Jboss CLI, whether you have created it successfully!
我怀疑您没有在 JBoss 中将 EmirDS 配置为数据源。以下是如何使用 Jboss CLI 检查您是否已成功创建它！
- From commandprompt, enter into JBOSS_HOME\bin
- Type connect YOUR_IP:YOUR_PORT (example 192.169.1.10:9999)
Type this to see whether your datasource is available or not:
/subsystem=datasources/data-source=EmirDS:test-connection-in-pool
- 从命令提示符进入 JBOSS_HOME\bin
- 输入connect YOUR_IP:YOUR_PORT（例如192.169.1.10:9999）
键入此内容以查看您的数据源是否可用：
/subsystem=datasources/data-source=EmirDS:test-connection-in-pool
You should see a msg like below if you are having a configured datasource named EmirDS
如果您有一个名为 EmirDS 的配置数据源，您应该会看到如下所示的消息
connection-in-pool
{
"outcome" => "success",
"result" => [true]
}
