【问题描述】：
我有 java EE 项目。我在服务器端使用 Spring Hibernate，在这个项目的客户端使用 Backbone、RequireJS、Jquery。我正在尝试使用 POST 方法保存，但返回 HTTP 415 错误。
我的 Get 方法工作正常。我在 Postman 上测试过。
我的网址：localhost:8080/rest/travel

【问题讨论】：
-
415 Unsupported Media Type 请求实体具有服务器或资源不支持的媒体类型。例如客户端上传图片为image/svg+xml，但服务器要求图片使用不同的格式。您可以发布正在发送的消息吗？

添加了我的帖子数据@MosheArad
-
您应该在此处添加 DTO 对象结构。模型类不是必需的。
-
@gaganbm 添加了 dto 和服务
-
我已经添加了答案。您可以通过 curl 或 postman 尝试，并设置正确的标题。
