我正在使用带有两个数据源的Wildfly 10.1版本，如下所示
<subsystem xmlns="urn:jboss:domain:datasources:4.0">
<datasources>
<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">

</datasource>
在我的java代码中（它将驻留在我在wildfly服务器上运行的应用程序的一个jar中）我已经制作了如下代码来获取数据源
Context initialContext = new InitialContext();
DataSource datasource = (DataSource)initialContext.lookup("java:jboss/datasources/jbpmDS");
connection = datasource.getConnection();
prepStatement = connection.prepareStatement(sqlQuery);
resultSet = prepStatement.executeQuery();
正好在datasource.getConnection（）行，我得到以下异常，
java.sql.SQLException: javax.resource.ResourceException: IJ000457: Unchecked throwable in managedConnectionReconnected() cl=org.jboss.jca.core.connectionmanager.listener.TxConnectionListener@183cd1f[state=NORMAL managed connection=org.jboss.jca.adapters.jdbc.local.LocalManagedConnection@1bd4a01 connection handles=0 lastReturned=1505387264452 lastValidated=1505387157714 lastCheckedOut=1505387264436 trackByTx=false pool=org.jboss.jca.core.connectionmanager.pool.strategy.OnePool@19c5e2b mcp=SemaphoreConcurrentLinkedQueueManagedConnectionPool@a50680[pool=MySQLDS1] xaResource=LocalXAResourceImpl@41a9e5[connectionListener=183cd1f connectionManager=74916c warned=false currentXid=null productName=MySQL productVersion=5.7.19-log jndiName=java:jboss/datasources/jbpmDS] txSync=null]
