Package feign

Interface Summary

Interface	Description
AsyncClient<C>	Submits HTTP requests asynchronously, with an optional context.
Capability	Capabilities expose core feign artifacts to implementations so parts of core can be customized around the time the client being built.
Client	Submits HTTP requests.
Contract	Defines what annotations and values are valid on interfaces.
DeclarativeContract.AnnotationProcessor<E extends Annotation>
DeclarativeContract.ParameterAnnotationProcessor<E extends Annotation>
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.

Class Summary

Class	Description
AsyncClient.Default<C>
AsyncClient.Pseudo<C>	A synchronous implementation of AsyncClient
AsyncFeign<C>	Enhances Feign to provide support for asynchronous clients.
AsyncFeign.AsyncBuilder<C>
Client.Default
Client.Proxied	Client that supports a Proxy.
Contract.BaseContract
Contract.Default
DeclarativeContract	Contract base implementation that works by declaring witch annotations should be processed and how each annotation modifies MethodMetadata
Feign	Feign's purpose is to ease development against http apis that feign restfulness.
Feign.Builder
Feign.ResponseMappingDecoder
InvocationHandlerFactory.Default
Logger	Simple logging abstraction for debug messages.
Logger.ErrorLogger	Logs to System.err.
Logger.JavaLogger	Logs to the category Logger at Level.FINE, if loggable.
Logger.NoOpLogger
MethodMetadata
Param.ToStringExpander
QueryMapEncoder.Default	Deprecated use BeanQueryMapEncoder instead.
ReflectiveAsyncFeign<C>
ReflectiveFeign
Request	An immutable request to an http server.
Request.Body	Request Body
Request.Options	Controls the per-request settings currently required to be implemented by all clients
RequestTemplate	Request Builder for an HTTP Target.
Response	An immutable response to an http invocation which only returns string content.
Response.Builder
Retryer.Default
Target.EmptyTarget<T>
Target.HardCodedTarget<T>
Types	Static methods for working with types.
Util	Utilities, typically copied in from guava, so as to avoid dependency conflicts.

Enum Summary

Enum	Description
CollectionFormat	Various ways to encode collections in URL parameters.
ExceptionPropagationPolicy
Logger.Level	Controls the level of logging.
Request.HttpMethod

Exception Summary

Exception	Description
AsyncJoinException	Thrown to encapsulate an underlying cause when using CompletableFuture.join() to convert an asynchronous call to a synchronous one.
FeignException	Origin exception type for all Http Apis.
FeignException.BadGateway
FeignException.BadRequest
FeignException.Conflict
FeignException.FeignClientException
FeignException.FeignServerException
FeignException.Forbidden
FeignException.GatewayTimeout
FeignException.Gone

FeignException.NotFound
FeignException.NotImplemented
FeignException.ServiceUnavailable
FeignException.TooManyRequests
FeignException.Unauthorized
FeignException.UnprocessableEntity
FeignException.UnsupportedMediaType
RetryableException	This exception is raised when the Response is deemed to be retryable, typically via an ErrorDecoder when the status is 503.

Annotation Types Summary

Annotation Type	Description
Body	A possibly templated body of a PUT or POST command.
Experimental	Indicates that a public API (public class, method or field) is subject to incompatible changes, or even removal, in a future release.
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, Body, POJO fields or beans properties when it expanding
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 uri template supplied in the value, permitting path and query variables, or just the http method.
