java POST contentType始终显示文本/纯文本，即使内容是XML

Question

我正在使用Apache Karaf, OSGi, JPA, JAX-RS & JAX-B.开发一个RESTful应用程序

在执行POST操作时，我面临一个问题，即在发送APPLICATION_XML时，我总是在日志中获取contentType as text/plain

以下是日志：

我尝试了其他操作，比如GET，DELETE，它们能够正确调用后续函数，但我似乎无法发送POST，并且每次都会显示这个问题

有人能帮我吗

从评论中，对邮递员的发展做了更多的研究

当前simple extension version不会根据与原始帖子正文标题关联的下拉列表中的内容类型来默认请求的内容类型。您需要显式地使用头来替换内容类型

看邮递员的Github，这似乎是not a new bug。深入研究问题，似乎还有一个Packaged App version of Postman可以正常运行，并为XML (application/xml)和XML (text/xml)提供不同的选项
