我使用Wildfly 10.1版本有两个数据源如下，一类使用wildfly数据源使用的InitialContext
<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">
<connection-url>jdbc:mysql://${dbhostname}:3306/${dbname}</connection-url>
<driver>h2</driver>
<security>
<user-name>sa</user-name>
<password>sa</password>
</security>
</datasource>
<datasource jta="true" jndi-name="java:jboss/datasources/jbpmDS" pool-name="MySQLDS" enabled="true" use-java-context="true" use-ccm="true">
<connection-url>jdbc:mysql://${dbhostname}:3306/${dbname}</connection-url>
<driver>mariadb</driver>
<new-connection-sql>select 1</new-connection-sql>
<pool>
<min-pool-size>2</min-pool-size>
<max-pool-size>10</max-pool-size>
<prefill>true</prefill>
<flush-strategy>FailingConnectionOnly</flush-strategy>
</pool>
<security>
<user-name>${dbuser}</user-name>

</security>
<validation>

<check-valid-connection-sql>select 2</check-valid-connection-sql>

</validation>
<timeout>

</statement>
</datasource>
在我的Java代码（这将居住在一个一罐我应用在wildfly服务器上运行），我做了如下的代码来获取数据源，
Context initialContext = new InitialContext();
DataSource datasource = (DataSource)initialContext.lookup("java:jboss/datasources/jbpmDS");
connection = datasource.getConnection();
prepStatement = connection.prepareStatement(sqlQuery);
resultSet = prepStatement.executeQuery();
在的DataSource.getConnection（）线没错，我刚开克以下例外，
java.sql.SQLException: javax.resource.ResourceException: IJ000457: Unchecked throwable in managedConnectionReconnected() cl=org.jboss.jca.core.conne[email protected][state=NORMAL managed conn[email protected]1bd4a01 connection handles=0 lastReturned=1505387264452 lastValidated=1505387157714 lastCheckedOut=1505387264436 trackByTx=false [email protected]19c5e2b [email protected][pool=MySQLDS1] [email protected][connectionListener=183cd1f connectionManager=74916c warned=false currentXid=null productName=MySQL productVersion=5.7.19-log jndiName=java:jboss/datasources/jbpmDS] txSync=null]
