I want to create a REST service that can return either JSON or XML. What request parameter do I set in the request to request a certain mime type? I know how to set it in the response, but there must be a way to request a certain one. Currently I do it in the URL

restServlet/engine/2WS2345

restServlet/engine/2WS2345

jsonServlet/engine/2WS2345

jsonServlet/engine/2WS2345

这让我得到 json 或 xml.但我想我读到有一个参数需要在请求中设置.我正在使用 JAVA...

This gets me json or xml. But I thought I read that there is a parameter to set in the request. I am using JAVA...

推荐答案

如果您使用 jersey，您可以使用 @Produces 注释轻松配置该方法.@Produces({"application/xml", "application/json"})

If you are using jersey you can easily configure the method with @Produces annotation. @Produces({"application/xml", "application/json"})

好消息是您仍然可以将 JAXB 对象作为返回类型.它将自动更改为所需的格式.除非在 Accept Header 中指定 MIME 类型，否则在上述情况下它将始终发送 xml.

Good thing is you can still have a JAXB object as a return type. It will automatically be changed to the required format. Unless MIME type is specified in the Accept Header it will always send xml in the above case.

参考 http://jersey.java.net/nonav/documentation/1.6/user-guide.html
