//@ContextConfiguration(classes = {JMSConfig.class})

@Autowired

}

/**

@Test
public void easyGetMsg() throws JMSException
{
while (true)
{
try

//TextMessage message = (TextMessage) jmsTemplate.receive();
//System.out.println(message.getText());
Message message = jmsTemplate.receive();
if (message instanceof ObjectMessage)
{
System.out.println("ObjectMsg Type");
System.out.println(((ObjectMessage) message).getObject());
}
else
{
System.out.println("Other Type..." + message.getJMSType());
}

}catch (Exception e)
{
System.out.println(e.getMessage());
}

}
}

}

异步消息监听器收到了一条消息:UserObj{id=1, username='NikoBleic', password='12345', role='None'}

由于配置了异步消息监听器，使用测试方法时，jmsTemplate.receive()将会与异步消息监听器争抢消息，谁抢到不一定。看下面示例

@Test
public void easyGetMsg() throws JMSException
{
while (true)
{
try
{
//TextMessage message = (TextMessage) jmsTemplate.receive();
//System.out.println(message.getText());
Message message = jmsTemplate.receive();
if (message instanceof ObjectMessage)
{
System.out.println("JMS模板接收到了消息:" + ((ObjectMessage) message).getObject());
System.out.println("");
}
else
{
System.out.println("Other Type..." + message.getJMSType());
}

}catch (Exception e)
{
System.out.println(e.getMessage());
}

}
}

执行后什么都不会输出，记控制台输出窗口为ConsoleA

@Test
public void easySendMsg()
{
for (int i = 0; i < 100; i++)
{
// 方法二
UserObj userObj = new UserObj(i, "NikoBleic", "12345", "None");
jmsTemplate.convertAndSend(userObj);
}

// 方法一
//jmsTemplate.send(queue, session -> {
//    return session.createTextMessage(userObj.toString());
//});

}

执行以后ConsoleA会输出如下，可以看到异步消息监听器与template.receive发生了争抢，但是以下显示的不是全部数据，因为执行发送程序的时候，发送端也会初始化项目中的异步消息监听器，导致总共有2个异步消息监听器和1个template一起争抢消息
