stomp content-type 标头为 xml 内容设置为纯文本

Question

我正在使用 stomp 从 ruby​​ 脚本向 ActiveMQ 发送 XML 内容

我明确地将内容类型标头设置为application/xml;charset=utf-8，如下所示

client.publish queue, xml, {'content-type'=>'application/xml;charset=utf-8'}

但是当我从使用 spring-integration 读取消息的 java 客户端读取消息时，内容类型是 text/plain。

因此，当调用 unmarshaller 时，解析失败并出现异常
