Rabbitmq 要发布到远程计算机上的消息队列吗

我想将运行在本地的springboot应用程序中的消息pojo发布到消息队列驻留在一台远程计算机上，但它给出了身份验证失败异常。我可以将同一对象发布到本地服务器中的消息队列

我正在使用Springbatch读取、处理和写入消息队列。我已使用AmqpItemWriter并尝试发布到消息队列。它工作得很好，并将消息发布到本地的消息队列中。当我将spring.rabbitmq.host属性从“localhost”更改为“xxx.xx.xx.xxx”时，远程计算机出现运行时异常，表明身份验证失败

下面是我的编写器代码，其中我有发布到消息队列的逻辑

@Component
public class Writer extends AmqpItemWriter<CsvWrapperPojo> {

    @Autowired
     @Qualifier("rabbitTemplate")
     private RabbitTemplate rabbitTemplate;

    public Writer(AmqpTemplate rabbitTemplate) {
        super(rabbitTemplate);
        // TODO Auto-generated constructor stub
    }

    /*@Autowired
    private CSVPostProcess csvPostProcess;*/


    @Override
    public void write(final List<? extends CsvWrapperPojo> items) throws Exception {
        // TODO Auto-generated method stub

        for(CsvWrapperPojo item : items){



            for(CSVPojo pojo :item.getGeneralPojoList()){

            rabbitTemplate.convertAndSend("spring-boot-rabbitmq-BulkSolve.async_BulkSolve_Msg", "BulkSolve_GeneralrequestQueue", pojo);
            }
            for(CSVPojo pojoSummary : item.getSummaryPojoList()){
                rabbitTemplate.convertAndSend("spring-boot-rabbitmq-BulkSolve_summary.async_BulkSolve_Msg", "BulkSolve_SummaryrequestQueue", pojoSummary);
            }
        }

    }



}

我已经安装了Rabbitmq，远程机器上也有相同的队列。但这里似乎没有进行身份验证。下面是我的异常堆栈跟踪。任何人都可以建议需要做什么才能将消息发布到远程机器

guest/guest

默认情况下不允许远程访问

看

默认情况下，禁止来宾用户从远程主机连接；它只能通过环回接口（即本地主机）进行连接。这适用于任何协议的连接。任何其他用户（默认情况下）都不会以这种方式受到限制

---

它接着解释了如果您真的想允许，如何重新配置代理。
