未找到 JMSTemplate Bean - Autowire 不起作用

Question

昨天还好好的，突然就不行了。我什么也没改变。我是 JMS 新手，遵循本教程：Tutorial

我只想使用 Azure 服务总线发送和接收消息。

错误信息：

Field jmsTemplate in com.example.messagesender.MessageSenderApplication required a bean of type 'org.springframework.jms.core.JmsTemplate' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

行动：

考虑在配置中定义“org.springframework.jms.core.JmsTemplate”类型的 bean。

Pom.xml：

                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

Java 文件：

@SpringBootApplication
@EnableJms
public class MessageSenderApplication implements CommandLineRunner {

    private static final Logger LOGGER = LoggerFactory.getLogger(MessageSenderApplication.class);
    private static final String QUEUE_NAME = "queue";

    @Autowired
    private JmsTemplate jmsTemplate;


    public static void main(String[] args) {
        SpringApplication.run(MessageSenderApplication.class, args);
    }

        @Override
        public void run (String...args){
            LOGGER.info("Sending message");
            jmsTemplate.convertAndSend(QUEUE_NAME, "Hello World");
        }

        @JmsListener(destination = QUEUE_NAME, containerFactory = "jmsListenerContainerFactory")
        public void receiveMessage (String message){
            LOGGER.info("Message received: {}", message);
        }
}

与教程中的完全一样。

我将不胜感激。谢谢！

您应该在 @Configuration 文件中创建一个 bean，但接收工厂作为参数。

 @Bean
 public JmsTemplate jmsTemplate(ConnectionFactory jmsConnectionFactory) {
     JmsTemplate template = new JmsTemplate();
     template.setConnectionFactory(jmsConnectionFactory);
     template.setPubSubDomain(true); // false for a Queue, true for a Topic
     return template;
 }
