Spring Integration JMS标头“ priority”必须为数字

Question

我将Spring Integration JMS 5.1.3与ActiveMQ结合使用，但发现映射优先级出错：

我的邮件标题如下：

我为优先级禁用了入站邮件头：

@Bean
public DefaultJmsHeaderMapper jmsHeaderMapper() {
    final DefaultJmsHeaderMapper mapper = new DefaultJmsHeaderMapper();
    {
        mapper.setMapInboundDeliveryMode(true);
        mapper.setMapInboundExpiration(true);
        mapper.setMapInboundPriority(false);
    }
    return mapper;
}

这个问题有解决方案吗？

Answer 1

对我来说，当我在自定义消息中使用标题“ priority”时，就会出现此问题。

 MessageBuilder.withPayload(val).setHeader("priority", true).build();

似乎“优先级”是不得使用的标头值。

更改为

 MessageBuilder.withPayload(val).setHeader("prio", true).build();

为我解决了问题。
