[大数据]rabbitMQ报错之 Only one ConfirmCallback is supported by each RabbitTemplate

设置rabbitTemplate和controller的scope都为prototype即可

   @Bean
    //设置rabbitTemplate的scope为:prototype
    @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
    public  RabbitTemplate noSingleRabbitTemplate() throws IOException, TimeoutException {
        RabbitTemplate rabbitTemplate = new RabbitTemplate(connection());
        //设置消息进入交换机后未被队列接收的消息不被丢弃由broker保存,flase为丢弃
        rabbitTemplate.setMandatory(true);
        rabbitTemplate.setReceiveTimeout(30000);
        rabbitTemplate.setReplyTimeout(30000);
        return rabbitTemplate;
    }

加粗样式

@RestController
//设置controller 的scope为:prototype
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
@RequestMapping("/sendMessage/")
public class SendMessageController {

    @Resource(name = "noSingleRabbitTemplate")
    private RabbitTemplate noSingleRabbitTemplate;
}
