我正在使用Hazelcast XA Transactions进行一些测试,并且在使用Bitronix作为事务管理器时遇到问题。
我遵循了Hazelcast官方文档:
http://docs.hazelcast.org/docs/3.5/manual/html/xatransactions.html
库版本:
Hazelcast: 3.5.4
Bitronix Transaction Manager: 2.1.4
Java: 1.7
法典:
测试方法:
@Test
public void hazelcastBitronixXATransactionTest() throws Exception{
try{
doHazelcastXATransactionTest(createInstance("myCluster"));
}catch(Exception e){
Assert.fail();
System.out.println("Other Exception:" + e.getMessage());
}
}
榛子实例创建方法:
private HazelcastInstance createInstance(String clusterName){
System.setProperty("hazelcast.logging.type", "slf4j");
Config config = new Config();
config.getGroupConfig().setName(clusterName);
config.getNetworkConfig().getJoin().getMulticastConfig().setEnabled(true);
TcpIpConfig tcpIpConfig = config.getNetworkConfig().getJoin().getTcpIpConfig();
tcpIpConfig.setEnabled(false);
return Hazelcast.newHazelcastInstance(config);
}
做方法:
private void doHazelcastXATransactionTest(HazelcastInstance hazelcastInstance) throws Exception{
BitronixTransactionManager btm = TransactionManagerServices.getTransactionManager();
btm.setTransactionTimeout(60);
btm.begin();
HazelcastXAResource xaResource = hazelcastInstance.getXAResource();
Transaction transaction = btm.getTransaction();
transaction.enlistResource(xaResource);
try {
TransactionContext context = xaResource.getTransactionContext();
TransactionalMap map = context.getMap("m");
map.put("key", "value");
transaction.delistResource(xaResource, XAResource.TMSUCCESS);
btm.commit();
} catch (Exception e) {
System.out.println("Exception do rollback:" + e.getMessage());
btm.rollback();
}
}
我收到一个BitronixSystemException
,在尝试登记 XA 资源transaction.enlistResource(xaResource)
时抛出。
完整的堆栈跟踪:
bitronix.tm.internal.BitronixSystemException: unknown XAResource HazelcastXaResource {myCluster}, it does not belong to a registered resource
有人遇到过这个问题吗?有什么线索吗?
显然Bitronix在使用它们之前需要注册XAResources。获得HazelcastXAResource
后,我在下面添加了行,它起作用了。
EhCacheXAResourceProducer.registerXAResource(xaResource.getName(), xaResource);
