HttpComponents Client 5.0 Alpha1 发布，主要更新如下: * Improved conformance to requirements and recommendations of the latest HTTP/1.1 protocol specification (RFC 7230, RFC 7231, RFC 7235) * Package name space changed to 'org.apache.hc.client5' * Maven group id changed to 'org.apache.httpcomponents.client5' * By default the maximum connections per route limit is set to 5 * By default connection request timeout and connect timeout are set to 3 minutes. HttpClient 5.0 releases can be co-located with earlier versions, meaning you can have both 5.x and 4.x on the classpath without experiencing jar hell. Please note that as of 5.0 HttpClient requires Java 1.7 or newer. Please note that at this point 5.0 APIs are considered API experimental and unstable and are expected to change in the coming releases without providing a migration path.
