JarCastingcf-java-client 
This is a facade that hides the official Cloud Foundry Java client (https://github.com/cloudfoundry/cf-java-client) under a synchronous API similar to the one it had back in version 1.1.4.RELEASE (see https://github.com/cloudfoundry/cf-java-client/tree/v1.1.4.RELEASE).
Introduction
The cf-java-client project is a Java language binding for interacting with a Cloud Foundry instance. It provides similar functionality to the Cloud Foundry command line client (https://github.com/cloudfoundry/cli), such as creating services and applications, binding services to applications or even registering service brokers. It communicates with the Cloud Foundry Controller by making HTTP requests to the controller's REST API, which is documented at https://apidocs.cloudfoundry.org/ (V2) and https://v3-apidocs.cloudfoundry.org/ (V3).
Usage
In order to use this client in your application, you need to include the following dependency in your pom.xml:
<dependency>
<groupId>com.sap.cloud.lm.sl</groupId>
<artifactId>cloudfoundry-client-facade</artifactId>
<version>...</version>
</dependency>
The latest version can always be found in Maven Central: https://mvnrepository.com/artifact/com.sap.cloud.lm.sl/cloudfoundry-client-facade
The following is a very simple sample application that connects to a Cloud Foundry instance, logs in, and displays some information about the Cloud Foundry account. When running the program, provide the Cloud Foundry target API endpoint, along with a valid user name and password as command-line parameters.
import java.net.MalformedURLException;
import java.net.URI;
import java.net.URL;
import com.sap.cloudfoundry.client.facade.domain.CloudApplication;
import com.sap.cloudfoundry.client.facade.domain.CloudServiceInstance;
import com.sap.cloudfoundry.client.facade.domain.CloudSpace;
public final class JavaSample {
public static void main(String[] args) {
String target = args[0];
String username = args[1];
String password = args[2];
CloudCredentials credentials = new CloudCredentials(username, password);
CloudControllerClient client = new CloudControllerClientImpl(getTargetURL(target), credentials);
client.login();
System.out.printf("%nSpaces:%n");
for (CloudSpace space : client.getSpaces()) {
System.out.printf(" %s\t(%s)%n", space.getName(), space.getOrganization()
.getName());
}
System.out.printf("%nApplications:%n");
for (CloudApplication application : client.getApplications()) {
System.out.printf(" %s%n", application.getName());
}
System.out.printf("%nServices%n");
for (CloudServiceInstance service : client.getServiceInstances()) {
System.out.printf(" %s\t(%s)%n", service.getName(), service.getLabel());
}
}
private static URL getTargetURL(String target) {
try {
return URI.create(target)
.toURL();
} catch (MalformedURLException e) {
throw new IllegalArgumentException("The target URL is not valid: " + e.getMessage());
}
}
}
Compiling and Packaging
The project is built using Apache Maven and you can use the following command to do so:
mvn clean install
Additionally, the project uses Immutables to generate value objects. As a result, it won't compile in IDEs like Eclipse or IntelliJ unless you also have an enabled annotation processor. See this guide for instructions on how to configure your IDE.
