HttpClientBuilder.@ThreadSafe @Deprecated public abstract class AbstractHttpClient extends CloseableHttpClient
HttpClient implementations.
This class acts as a facade to a number of special purpose handler or
strategy implementations responsible for handling of a particular aspect
of the HTTP protocol such as redirect or authentication handling or
making decision about connection persistence and keep alive duration.
This enables the users to selectively replace default implementation
of those aspects with custom, application specific ones. This class
also provides factory methods to instantiate those objects:
HttpRequestExecutorcreateRequestExecutor() must be
implemented by concrete super classes to instantiate this object.
BasicHttpProcessorcreateHttpProcessor() must be
implemented by concrete super classes to instantiate this object.
HttpRequestRetryHandlercreateHttpRequestRetryHandler() must be
implemented by concrete super classes to instantiate this object.
ClientConnectionManagerConnectionReuseStrategycreateConnectionReuseStrategy() must be
implemented by concrete super classes to instantiate this object.
ConnectionKeepAliveStrategycreateConnectionKeepAliveStrategy() must be
implemented by concrete super classes to instantiate this object.
CookieSpecRegistrycreateCookieSpecRegistry() must be implemented by concrete
super classes to instantiate this object.
CookieStorecreateCookieStore() must be implemented by
concrete super classes to instantiate this object.
AuthSchemeRegistrycreateAuthSchemeRegistry() must be implemented by concrete
super classes to instantiate this object.
CredentialsProvidercreateCredentialsProvider()
must be implemented by concrete super classes to instantiate
this object.
AuthenticationStrategycreateTargetAuthenticationStrategy() must be implemented
by concrete super classes to instantiate this object.
AuthenticationStrategycreateProxyAuthenticationStrategy() must be implemented
by concrete super classes to instantiate this object.
HttpRoutePlannercreateHttpRoutePlanner() must be implemented
by concrete super classes to instantiate this object.
RedirectStrategyUserTokenHandlercreateUserTokenHandler() must be implemented by
concrete super classes to instantiate this object.
This class also maintains a list of protocol interceptors intended
for processing outgoing requests and incoming responses and provides
methods for managing those interceptors. New protocol interceptors can be
introduced to the protocol processor chain or removed from it if needed.
Internally protocol interceptors are stored in a simple
ArrayList. They are executed in the same natural order
as they are added to the list.
AbstractHttpClient is thread safe. It is recommended that the same
instance of this class is reused for multiple request executions.
When an instance of DefaultHttpClient is no longer needed and is about
to go out of scope the connection manager associated with it must be
shut down by calling ClientConnectionManager.shutdown()!
