Openfeign How to use @Headers annotation with different produces and consumes types?
问题
我想在我的项目中使用Feign客户端，但某些端点会生成 text/plain，同时消耗 application/json。目前我有类似这样的代码。该方法生成 plain/text，将会消耗 application/json。有没有办法解决这个问题？请注意，这不是一个Spring Boot应用程序，只是一个Java/Maven项目。
@Headers("Content-Type: text/plain")
@RequestLine(value = "POST /containers/{id}/services")
String startService(@Param("id") String id, String serviceType);
在Jaxrs中，我们使用以下头部来指定此方法或类使用的媒体类型。
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.TEXT_PLAIN)
我希望能够做同样的事情，但在Feign客户端中没有Produces或Consumes头部。只有@Headers，您可以在其中指定内容类型。我想知道这个注解的 Content-Type 是用于消耗和生成的，还是仅用于消耗，或者是否可以为生成和消耗分别指定不同的类型？

I want to use Feign client in my project but some endpoints produces text/plain while consuming application/json. Right now I have something like this. Method is producing plain/text and will consume application/json. Is there a way to fix it? Note that this is not a Spring boot application. It's just a Java/Maven project.
@Headers("Content-Type: text/plain")
@RequestLine(value = "POST /containers/{id}/services")
String startService(@Param("id") String id, String serviceType);
In Jaxrs we use below headers to specify the mime types that this method or class uses.
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.TEXT_PLAIN)
I want to be able to do same thing but there is no Produces or consumes headers in feign client. There is only @Headers there you can specify content type. I wonder if this annotation's Content-Type is used for both consuming and producing, or just for consuming, or if you can specify different types for both producing and consuming?

@Headers content should look like this:
@Headers({
"Content-Type: application/json",
"Accept: text/plain",
})
With `Accept` header in place, you tell feign client to produce JSON (in your case it is serviceType passed into the method) and consume text/plain.
