java - Spring Amqp 在 springframework RetryCallback 类中有 NoClassDefFoundError

标签 java rabbitmq spring-amqp spring-rabbit

我一直在从事分布式 Web 项目，我想在其中使用使用 RabbitMq 的 Spring amqp。我在我的项目中使用 springFramework 版本 4.1.6。为此，我在文件 pom.xml 中添加了以下依赖项。

<dependency>
            <groupId>com.rabbitmq</groupId>
            <artifactId>amqp-client</artifactId>
            <version>3.5.7</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.amqp</groupId>
            <artifactId>spring-amqp</artifactId>
            <version>1.5.3.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.amqp</groupId>
            <artifactId>spring-rabbit</artifactId>
            <version>1.5.3.RELEASE</version>
        </dependency>

另外，我在web.xml下面放了一个RabbitMQ的配置文件

<?xml version="1.0" encoding="UTF-8"?>

        </rabbit:bindings>
    </rabbit:topic-exchange>

    <bean id="rabbitListenerContainerFactory"
        class="org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory">
        <property name="connectionFactory" ref="connectionFactory" />
        <property name="concurrentConsumers" value="3" />
        <property name="maxConcurrentConsumers" value="10" />
    </bean>

    <rabbit:annotation-driven container-factory="rabbitListenerContainerFactory" />

    <rabbit:listener-container
        connection-factory="connectionFactory" />

</beans>

另外，为了发送，我写了方法

@Service
public class PrmSpringRabbitMessageSender {
   @Autowired
   private AmqpTemplate amqpTemplate;

   public void sendMessage(String queueName, String message) {
      amqpTemplate.convertAndSend(queueName, message);
   }
}

并接收如下消息:

@Component
public class PrmSpringRabbitMessageReceiver {
   @RabbitListener(queues = "myQueue")
   public void handleMessage(String data) {
      System.out.println("Received Message : " + data);
   }
}

但是当我运行该项目时，我遇到了如下所示的 java.lang.NoClassDefFoundError:

为了解决这个问题，我将下面的依赖添加到我的项目中:

<dependency>
            <groupId>org.springframework.retry</groupId>
            <artifactId>spring-retry</artifactId>
            <version>1.0.3.RELEASE</version>
        </dependency>

不幸的是，我还有另一个与缺少另一个类有关的错误:

如果有人能帮助我解决这个问题，我将不胜感激。

最佳答案

你错过的类在这个库中:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-messaging</artifactId>
  <version>4.2.4.RELEASE</version>
</dependency>

一般来说，如果您错过了一些晦涩的类(为第三方获取 NoClassDefFoundError)，最好的方法是使用:

central Nexus search by classname
