Question

我还没有完成从Jonas到Wildfly的迁移，但是当我在UAT环境中进行测试时，我意识到一些连接泄漏，例如：

<script src="http://threejs.org/build/three.min.js"></script>
<script src="http://threejs.org/examples/js/controls/OrbitControls.js"></script>

当服务器在Jonas上运行时，没有连接泄漏。然后，我决定检查我们在项目中使用的每个连接：尝试使用ressource块的只有标准JDBC，除了使用connection.setAutocommit（false）的“事务”。

例如：

  javax.resource.ResourceException: IJ000453: Unable to get managed 
  connection for java:
  java.sql.SQLException: javax.resource.ResourceException: IJ000453: Unable 
  to get managed connection for java:/jdbc/xxxxx/xxxxDs
    at org.jboss.jca.adapters.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:154)
    at zz.pp.xx.pp.hh.kk.j.getConnection(Unknown Source)
 Caused by: javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/jdbc/xxxxx/xxxxDs

    at org.jboss.jca.core.connectionmanager.tx.TxConnectionManagerImpl.getManagedConnection(TxConnectionManagerImpl.java:421)
    at org.jboss.jca.core.connectionmanager.AbstractConnectionManager.allocateConnection(AbstractConnectionManager.java:515)
    at org.jboss.jca.adapters.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:146)
    ... 55 more
Caused by: javax.resource.ResourceException: IJ000655: No managed connections available within configured blocking timeout (30000 [ms])
    at org.jboss.jca.core.connectionmanager.pool.mcp.SemaphoreArrayListManagedConnectionPool.getConnection(SemaphoreArrayListManagedConnectionPool.java:511)
    at org.jboss.jca.core.connectionmanager.pool.AbstractPool.getSimpleConnection(AbstractPool.java:461)
    at org.jboss.jca.core.connectionmanager.pool.AbstractPool.getConnection(AbstractPool.java:433)
    at org.jboss.jca.core.connectionmanager.AbstractConnectionManager.getManagedConnection(AbstractConnectionManager.java:379)
  ... 58

有人可以解释一下为什么Wildfly与connection.setAutocommit（false）不兼容吗？

将Jonas迁移到Wildfly：connection.commit（）问题
