我真的不知道瓶颈在哪里。
我从零开始创建了一个新项目，试图隔离变量。
现在我有一些简单的事情
生产者：
public void createTasks() throws JMSException {
for(int i=0;i<1000;i++){
if (i%100 == 0){
System.out.println(i);
}
MyEntity my = new MyEntity("xyz"+i);
my = this.baseService.getMyEntityDAO().addAndFlush(my);
jmsService.enqueue(my);
}
}
JMS
@Singleton
@Lock(LockType.WRITE)
public class JmsService implements Serializable{
public void enqueue(MyEntity target) throws JMSException{
Connection connection = null;
Session session = null;
try {
ConnectionFactory connectionFactory = this.connectionFactory;
connection = connectionFactory.createConnection();
connection.start();
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = this.driverJobQueue;
MessageProducer producer = session.createProducer(queue);
Message message = session.createMessage();
message.setLongProperty("id",target.getId());
message.setStringProperty("type", "xyz");
producer.send(message,DeliveryMode.PERSISTENT,1,0);
} finally {
// Clean up
if (session != null){
session.close();
}
if (connection != null){
connection.close();
}
}
}
