Interface Summary

Interface	Description
Client	Submits HTTP requests.
Contract	Defines what annotations and values are valid on interfaces.
InvocationHandlerFactory	Controls reflective method dispatch.
InvocationHandlerFactory.MethodHandler	Like InvocationHandler.invoke(Object, java.lang.reflect.Method, Object[]), except for a single method.
Param.Expander
QueryMapEncoder	A QueryMapEncoder encodes Objects into maps of query parameter names to values.
RequestInterceptor	Zero or more RequestInterceptors may be configured for purposes such as adding headers to all requests.
Response.Body
ResponseMapper	Map function to apply to the response before decoding it.
Retryer	Cloned for each invocation to Client.execute(Request, feign.Request.Options).
Target<T>	relationship to JAXRS 2.0 Similar to javax.ws.rs.client.WebTarget, as it produces requests.

Annotation Types Summary

Annotation Type	Description
Body	A possibly templated body of a PUT or POST command.
HeaderMap	A template parameter that can be applied to a Map that contains header entries, where the keys are Strings that are the header field names and the values are the header field values.
Headers	Expands headers supplied in the value.
Param	A named template parameter applied to Headers, RequestLine or Body
QueryMap	A template parameter that can be applied to a Map that contains query parameters, where the keys are Strings that are the parameter names and the values are the parameter values.
RequestLine	Expands the request-line supplied in the value, permitting path and query variables, or just the http method.
