当我关闭JBOSS服务器(ctrl+C)时会导致以下异常

Terminate batch job (Y/N)?

在contextDestroyed（..）

中

            jobScheduler.unscheduleJob(PaaSConsoleUtil.PAAS_CLEANUP_JOB_NAME, PaaSConsoleUtil.JOB_GROUP);

        jobScheduler.shutdown(true);
        //scheduler.shutdown();
        executor.shutdown();   

        //clear the connection pool.
        ConnectionPool.clear();
        //Closing HttpClientIdleConnectionTimeoutThread through connector utils.
        ConnectorUtils.shutdown();

        //Shutdown the monitoring async executor task.
        SyncEventListenerUtil.shutdownThreadPool();

        //Destroy all console related threads here and deregister all drivers.
        ConsoleContextUtil consoleUtil = new ConsoleContextUtil(logger, false);
        consoleUtil.consoleContextDestroyed();

Answer 1

我遇到了同样的问题，现在我已经找到了https://issues.jboss.org/browse/WFLY-944中描述的原因。为避免这种情况而在那里提出的解决方案是将jndi声明为Web应用程序中的资源，以便在应用程序终止之前不与jboss服务器解除绑定。

要实现此目的，请在web.xml中添加以下部分，该部分设置对名为“jdbc / myDS”的jboss jndi的引用。

<resource-ref>
<res-ref-name>jdbc/myDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<lookup-name>java:jboss/datasources/ConsoleDB</lookup-name>
</resource-ref>

然后从你的代码部分查找“java：jboss / datasources / ConsoleDB”而不是查找我认为你用

这样的实际jndi

DataSource ds =（DataSource） ctx.lookup（ “Java的：的JBoss /数据源/ ConsoleDB”）;

，您现在应该查找“java：comp / env / jdbc / myDS”，它将引用您放在web.xml中的资源，该资源实际指向实际的jndi（我们之前指定为'lookup-在web.xml中添加的部分中名为'xml属性'：

DataSource ds =（DataSource） ctx.lookup（ “Java的：comp / env的/ JDBC / myDS”）;

Answer 2

我通过将数据源添加到persistence.xml（不需要web.xml）并在数据源上使用@Resource（lookup =“datasourceName”）注释来解决它。您可以使用@Resource注释来节省大量样板代码，因为您不必担心打开和关闭连接等。只需调用“datasource.getConnection（）”即可检索现有连接。你让容器完成工作:-D
