API Reference

Public Methods

Method	Description
delegate	Constructs a DecoratedFeignComponent wrapping the given delegate.
loadInstanceFromContextFactory	Loads a component instance of the given type from the NamedContextFactory,
contextId	Returns the Feign client context ID associated with this decorated component.
refresh	Refreshes this component by clearing the delegate, causing the next call to
getDefaultConfiguration	Returns the Feign component type class used to resolve the delegate implementation.
getCurrentConfiguration	Returns the FeignClientConfiguration for the current Feign client context ID.

Method Details

delegate

public T delegate()

Constructs a DecoratedFeignComponent wrapping the given delegate.

Example Usage:

`// Typically invoked via a subclass constructor
super(contextId, contextFactory, clientProperties, delegate);
`

loadInstanceFromContextFactory

public <T> T loadInstanceFromContextFactory(String contextId, Class<T> componentType)

Loads a component instance of the given type from the NamedContextFactory, falling back to direct instantiation if the bean is not available.

Example Usage:

`Decoder decoder = decoratedFeignComponent.loadInstanceFromContextFactory("my-client", Decoder.class);
`

contextId

public String contextId()

Returns the Feign client context ID associated with this decorated component.

Example Usage:

`String id = decoratedFeignComponent.contextId();
`

refresh

public void refresh()

Refreshes this component by clearing the delegate, causing the next call to #delegate() to reload the instance from the context factory.

Example Usage:

`decoratedFeignComponent.refresh();
`

getDefaultConfiguration

public FeignClientConfiguration getDefaultConfiguration()

Returns the Feign component type class used to resolve the delegate implementation. Subclasses must implement this to return the appropriate configuration class.

Example Usage:

`Class type = decoratedFeignComponent.componentType();
`

getCurrentConfiguration

public FeignClientConfiguration getCurrentConfiguration()

Returns the FeignClientConfiguration for the current Feign client context ID.

Example Usage:

`FeignClientConfiguration currentConfig = decoratedFeignComponent.getCurrentConfiguration();
`
