Class Invocation

java.lang.Object

feign.interceptor.Invocation

@Experimental
public final class Invocation
extends Object

Context for a single method invocation passed to MethodInterceptors. Exposes the resolved RequestTemplate (mutable until the request is sent), the contract's MethodMetadata, the raw method arguments, and — after the chain has executed the HTTP call — the resulting Response.

MethodMetadata	methodMetadata()
RequestTemplate	requestTemplate() The mutable, contract-resolved request template.
Response	response() The HTTP Response captured after the framework's terminal chain step.

Method Detail

target

public Target<?> target()

methodMetadata

public MethodMetadata methodMetadata()

method

public Method method()

Convenience accessor for the underlying reflective Method.

requestTemplate

public RequestTemplate requestTemplate()

The mutable, contract-resolved request template. Mutations are visible downstream.

arguments

public Object[] arguments()

Raw arguments passed to the proxied method. May be null for no-arg methods.

body

public Object body()

Returns the typed argument that will be serialized as the request body, or null if the method has no body parameter or it was passed as null.

response

public Response response()

The HTTP Response captured after the framework's terminal chain step. Returns null when the chain has not yet executed the HTTP call, or when the call failed before a response was received.

response

@Experimental
public void response(Response response)

Framework-internal setter populated by the terminal chain step after the HTTP client returns. Calling this from interceptor code is unsupported and may break in future versions.
