Spring Amqp在springframework RetryCallback类中有NoClassDefFoundError
我一直在研究分布式Web项目，我想在其中使用带有RabbitMq的Spring amqp。 我在我的项目中使用springFramework版本4.1.6。 为此，我将以下依赖项添加到文件pom.xml中。
com.rabbitmq amqp-client 3.5.7 org.springframework.amqp spring-amqp 1.5.3.RELEASE org.springframework.amqp spring-rabbit 1.5.3.RELEASE 另外，我将下面的RabbitMQ配置文件放在web.xml中
此外，我写了一些方法来发送
@Service public class PrmSpringRabbitMessageSender { @Autowired private AmqpTemplate amqpTemplate; public void sendMessage(String queueName, String message) { amqpTemplate.convertAndSend(queueName, message); } }
并接收以下消息：
@Component public class PrmSpringRabbitMessageReceiver { @RabbitListener(queues = "myQueue") public void handleMessage(String data) { System.out.println("Received Message : " + data); } }
但是当我运行项目时，我遇到了如下的java.lang.NoClassDefFoundError：

为了解决这个问题，我将下面的依赖项添加到我的项目中：
org.springframework.retry spring-retry 1.0.3.RELEASE
不幸的是，我还有另一个与缺少另一个类有关的错误：

如果有人帮我解决这个问题，我将非常感激。
你在这里想念的课程在这个lib中：
org.springframework spring-messaging 4.2.4.RELEASE
一般来说，如果你错过了一些晦涩的类（第三方获得NoClassDefFoundError），最好的方法是使用：
