Package org.glassfish.jersey.apache.connector

Class ApacheConnectorProvider

java.lang.Object

org.glassfish.jersey.apache.connector.ApacheConnectorProvider

All Implemented Interfaces:

ConnectorProvider

public class ApacheConnectorProvider
extends Object
implements ConnectorProvider

Connector provider for Jersey connectors that utilize Apache HTTP Client to send and receive HTTP request and responses.

The following connector configuration properties are supported:

• ApacheClientProperties.CONNECTION_CLOSING_STRATEGY
• ApacheClientProperties.CONNECTION_MANAGER
• ApacheClientProperties.CONNECTION_MANAGER_SHARED
• ApacheClientProperties.CONNECTION_CLOSING_STRATEGY
• ApacheClientProperties.CREDENTIALS_PROVIDER
• ApacheClientProperties.DISABLE_COOKIES
• ApacheClientProperties.KEEPALIVE_STRATEGY
• ApacheClientProperties.PREEMPTIVE_BASIC_AUTHENTICATION
• ClientProperties.PROXY_URI
• ClientProperties.PROXY_USERNAME
• ClientProperties.PROXY_PASSWORD
• ClientProperties.REQUEST_ENTITY_PROCESSING - default value is RequestEntityProcessing.CHUNKED
• ApacheClientProperties.REQUEST_CONFIG
• ApacheClientProperties.RETRY_HANDLER
• ApacheClientProperties.REUSE_STRATEGY
• ApacheClientProperties.USE_SYSTEM_PROPERTIES

Connector instances created via this connector provider use chunked encoding as a default setting. This can be overridden by the ClientProperties.REQUEST_ENTITY_PROCESSING. By default the ClientProperties.CHUNKED_ENCODING_SIZE property is only supported when using the default org.apache.http.conn.HttpClientConnectionManager instance. If custom connection manager is used, then chunked encoding size can be set by providing a custom org.apache.http.HttpClientConnection (via custom org.apache.http.impl.conn.ManagedHttpClientConnectionFactory) and overriding it's createOutputStream method.

Use of authorization by the AHC-based connectors is dependent on the chunk encoding setting. If the entity buffering is enabled, the entity is buffered and authorization can be performed automatically in response to a 401 by sending the request again. When entity buffering is disabled (chunked encoding is used) then the property ApacheClientProperties.PREEMPTIVE_BASIC_AUTHENTICATION must be set to true.

If a ClientResponse is obtained and an entity is not read from the response then InboundMessageContext.close() MUST be called after processing the response to release connection-based resources.

Registration of ApacheHttpClientBuilderConfigurator instance on the Client is supported. A configuration provided by ApacheHttpClientBuilderConfigurator will override the HttpClientBuilder configuration set by using the properties.

If a response entity is obtained that is an instance of Closeable then the instance MUST be closed after processing the entity to release connection-based resources.

The following methods are currently supported: HEAD, GET, POST, PUT, DELETE, OPTIONS, PATCH and TRACE.
