MessageListener onMessage方法中的Spring RabbitMQ断点

问题描述 投票:0回答:1

我在基于Spring RabbitMQ的应用程序的消费者端有这个代码 -

public class MyReceiver implements ChannelAwareMessageListener {

    public MyReceiver() {
        super();
    }

    @Autowired
    @Qualifier("some_name")
    private SomeDependency dep;

    @Override
    public void onMessage(Message message, Channel channel) throws Exception {
        try {
            String messageString = new String(message.getBody());
            if (StringUtils.isNotEmpty(messageString)) {
                LOGGER.info("Received Message is:" + messageString);

                dep.someMethod();
                channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);
            }
        } catch (Exception e) {

        }
    }

}

当我在try中的第一行放置break时,控制到达断点并继续执行后面的LOGGER.info()调用,但是其他行在大多数时间没有执行,并且控制在其他地方之前移出到达那里。如何确保执行onMessage中的整个代码?

这是控制台输出 -

在catch块中添加异常日志记录(永远不会捕获异常,而不会在catch块中执行任何有用的操作),并在try块的最后一行添加日志记录。

编辑:

我找到了这个话题:http://rabbitmq.1065348.n5.nabble.com/reply-code-406-reply-text-PRECONDITION-FAILED-unknown-delivery-tag-td21310.html

我认为调用channel.basicAck可能是多余的,尝试删除它。
