This article introduces the knowledge of "how to develop OpenStack in OpenStack4j". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

I. explanation

The project was built using Maven (3.x) and then using the openstack JAVA version of the SDK tool openstack4j.

Note: before development, the host information of the openstack control node must be added to the hosts file of the host. As shown in the following figure, modify the hosts file under the windows system (file address: C:\ Windows\ System32\ drivers\ etc\ hosts)

II. Pom.xml setting

Add dependencies on slf4j-api, slf4j-log4j12 and openstack4j in the pom file. Since the jdk used in my development environment is 1.7, the version of openstack4j used is 2.x. If the jdk is 1.8, 3.x can be used.

Org.slf4j slf4j-api 1.7.21 org.slf4j slf4j-log4j12 1.7.21 org.pacesys openstack4j 2.20 withdeps

Third, test code

The test code of java is written as follows, which implements the following functions: 1) create an OSClient instance; 2) obtain container information in Swfit; 3) create a new container named xhhuangContainer

Package com.xhhuang.openstack;import java.util.HashMap;import java.util.List;import java.util.Map;import org.openstack4j.model.identity.User;import org.openstack4j.model.storage.object.SwiftAccount;import org.openstack4j.model.storage.object.SwiftContainer;import org.openstack4j.model.storage.object.options.CreateUpdateContainerOptions;import org.openstack4j.openstack.OSFactory;import org.openstack4j.api.OSClient / * Hello world! * * / public class App {public static void main (String [] args) {/ / start certification System.out.println ("start certification:") OSClient os = OSFactory.builder () .customers ("http://10.3.1.123:5000/v2.0"). Customers (" pipsCloud ") "pipsCloudTeam") .tenantName ("pipsCloud") .authenticate () System.out.println ("complete authentication:" + os.toString ()); System.out.println ("get Swift account:"); SwiftAccount swiftAccount = os.objectStorage (). Account (). Get (); System.out.println (swiftAccount); System.out.println ("get object storage metadata information:"); Map metadata = new HashMap () Boolean result = os.objectStorage () .account () .updateMetadata (metadata); System.out.println (result); System.out.println ("get Container Information:"); List
