SpringBoot3.0整合RocketMQ时出现未能加载bean文件

问题

APPLICATION FAILED TO START

Description:

Field rocketMQTemplate in com.spt.message.service.MqProducerService required a bean of type ‘org.apache.rocketmq.spring.core.RocketMQTemplate’ that could not be found.

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

Action:

Consider defining a bean of type ‘org.apache.rocketmq.spring.core.RocketMQTemplate’ in your configuration.

解决方案

定义一个配置类

@Configuration
public class RocketMqConfig {
    @Value("${rocketmq.producer.group}")
    private String producerGroup;

    @Value("${rocketmq.name-server}")
    private String nameServer;

    /**
     * 由于使用的Spring版本是3.0.0以上，与rocketMq不是很兼容，对于rocketMqTemplate
     * 的自动注入存在差异，如果不采用这种方式注入则会报出缺少bean的信息
     */
    @Bean("RocketMqTemplate")
    public RocketMQTemplate rocketMqTemplate(){
        RocketMQTemplate rocketMqTemplate = new RocketMQTemplate();
        DefaultMQProducer defaultMqProducer = new DefaultMQProducer();
        defaultMqProducer.setProducerGroup(producerGroup);
        defaultMqProducer.setNamesrvAddr(nameServer);
        rocketMqTemplate.setProducer(defaultMqProducer);
        return rocketMqTemplate;
    }
}
