Spring Amqp 在 springframework RetryCallback 类中有 NoClassDefFoundError [英] Spring Amqp has NoClassDefFoundError in springframework RetryCallback class
本文介绍了Spring Amqp 在 springframework RetryCallback 类中有 NoClassDefFoundError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我一直在研究一个分布式 Web 项目，我想在其中使用 Spring amqp 和 RabbitMq.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.
I have been working on a distributed web project and I want to utilize Spring amqp using RabbitMq in it. I use springFramework version 4.1.6 in my project. To do this, I have added the following dependencies to the file pom.xml.
<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配置文件
In addition, I place a RabbitMQ configuration file below in web.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"

<rabbit:admin connection-factory="connectionFactory" />
<rabbit:queue name="myQueue" />
<rabbit:topic-exchange name="myExchange">
<rabbit:bindings>
<rabbit:binding queue="myQueue" pattern="myQueue"></rabbit:binding>

</rabbit:topic-exchange>
<bean id="rabbitListenerContainerFactory"

<property name="connectionFactory" ref="connectionFactory" />

<property name="maxConcurrentConsumers" value="10" />
</bean>
<rabbit:annotation-driven container-factory="rabbitListenerContainerFactory" />
<rabbit:listener-container
connection-factory="connectionFactory" />
</beans>
此外，我写了方法来发送
Furthermore, I wrote methods in order to send
@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:
But when I run the project, I faced a java.lang.NoClassDefFoundError like below:

为了解决这个问题，我在我的项目中添加了以下依赖项:
To solve the problem, I added the dependency below to my project:
<dependency>
<groupId>org.springframework.retry</groupId>
<artifactId>spring-retry</artifactId>
<version>1.0.3.RELEASE</version>
</dependency>
不幸的是，我还有另一个错误，与缺少另一个类有关:
Unfortunately, I still have another error which is related to lack of another class:

如果有人帮助我解决这个问题，我将不胜感激.
I will really appreciate if any one help me tackle this problem.
推荐答案
你错过的课程在这个库中:
The class you miss here is in this lib:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-messaging</artifactId>
<version>4.2.4.RELEASE</version>
</dependency>
通常，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:
In general if you miss some obscure class (getting NoClassDefFoundError for a third-party) the best way is to use:
