Question

我想从本地运行的springboot应用程序将消息pojo发布到驻留在其中一台远程机器上的消息队列，但是它给Authentication失败提供了例外。我可以将同一对象发布到本地的消息队列中。

我正在使用Springbatch读取，处理和写入消息队列。我已经使用过AmqpItemWriter并尝试发布到消息队列。它运作良好，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Writer代码，在这里我有逻辑可以发布到消息队列。

@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);
            }
        }

    }



}

下面是application.properties

server.port=9060
spring.rabbitmq.dynamic=true
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.host=xxx.xx.xx.xxx(Remote machine IP)
spring.batch.job.enabled=false

我已经安装了Rabbitmq，并且远程计算机上也有相同的队列。但是似乎认证没有在这里进行。以下是我的异常堆栈跟踪。谁能建议将消息发布到远程计算机需要做什么。

Answer 1

guest/guest默认情况下不允许远程访问。

请参见"guest" user can only connect from localhost。

默认情况下，禁止来宾用户从远程主机进行连接；它只能通过回送接口（即本地主机）进行连接。无论协议如何，这都适用于连接。（默认情况下）其他任何用户都不会受到这种方式的限制。

继续说明如果您确实想允许它重新配置代理。
