Interface HttpInvokerRequestExecutor

All Known Implementing Classes:

AbstractHttpInvokerRequestExecutor, HttpComponentsHttpInvokerRequestExecutor, SimpleHttpInvokerRequestExecutor

public interface HttpInvokerRequestExecutor

Strategy interface for actual execution of an HTTP invoker request. Used by HttpInvokerClientInterceptor and its subclass HttpInvokerProxyFactoryBean.

Two implementations are provided out of the box:

• SimpleHttpInvokerRequestExecutor: Uses JDK facilities to execute POST requests, without support for HTTP authentication or advanced configuration options.
• HttpComponentsHttpInvokerRequestExecutor: Uses Apache's Commons HttpClient to execute POST requests, allowing to use a preconfigured HttpClient instance (potentially with authentication, HTTP connection pooling, etc).

Since:

1.1
