报错的原因是在配置spring-rabbitmq.xml文件时的connectionFactory与redis的connectionFactory的Id命名冲突
改好之后有报错：
spring报错org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.xxx] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
原因：对应要注入的实现类没有 加注解，如dao层 @Repository 如service层 @Service
解决：在相应的实现类加上注解即可
将MQProducer接口和MQProducerImpl放在Service层，并且加上@Service注解即可
