Package de.iip_ecosphere.platform.examples

Class SpringStartup

java.lang.Object

de.iip_ecosphere.platform.examples.SpringStartup

public class SpringStartup
extends Object

Spring Cloud Stream emulating startup code. Considers system properties ("iip.test.java8" and "iip.springStart.args") as well as command line arguments "iip.test.brokerPort" (broker port to use) and ARG_STOP (auto-stop time in ms). In contrast to a startup of an application with the platform and the service manager, services are started here in arbitrary sequence without considering their dependencies. Testing input shall consider a certain startup time before causing actions.

SpringStartup

public SpringStartup()

Method Details

main

public static void main(String[] args)

Main program to start the application. Takes into account additional args via system property "iip.springStart.args" to allow for maven basic execution with fixed parameters in POM and additional arguments passed in via "iip.springStart.args".

Parameters:

args - the command line arguments; the first is the artifact file to start, the remaining is passed on to Spring

start

public static final void start(String... args)

Starts the application. Used from generated templates. Do not change signature.

Parameters:

args - the command line arguments; the first is the artifact file to start, the remaining is passed on to Spring

start

public static void start(File artifact,
 String... args)

Starts the application. Used from examples. Do not change signature.

Parameters:

artifact - the artifact file (JAR/ZIP) containing the application

args - the command line arguments

addAasNotificationMode

private static void addAasNotificationMode(String[] args,
 List<String> cmdArgs)

Retrieves the AAS notification mode from cmd line argument Starter.ARG_AAS_NOTIFICATION and adds it to cmdArgs.

Parameters:

args - the command line arguments

cmdArgs - the command line arguments to be modified as a side effect

See Also:

• Starter.setAasNotificationMode(String[], NotificationMode)

addAppId

private static void addAppId(String[] args,
 List<String> cmdArgs)

If given in args, adds Starter.PARAM_IIP_APP_ID to cmdArgs.

Parameters:

args - the command line arguments

cmdArgs - the command line arguments to be modified as a side effect

start

public static void start(File artifact,
 boolean doExit,
 Consumer<ProcessBuilder> procCfg,
 String... args)

Starts the application. Considers system property "iip.test.java8" as java binary for Java 8 if not running under Java 8.

Parameters:

artifact - the artifact file (JAR/ZIP) containing the application

doExit - whether at the end of the timing if a timeout is given by args the JVM shall be shut down

procCfg - a configurer for the process being generated, may be null for none

args - the command line arguments

getArtifacts

private static Collection<de.iip_ecosphere.platform.services.spring.SpringCloudArtifactDescriptor> getArtifacts(File file)

Returns the artifact descriptor(s) from the deployment descriptor in file.

Parameters:

file - the file to read the artifact from

Returns:

the artifact descriptor(s), may be empty
