Class TaskLaunchRequestFunctionConfiguration

java.lang.Object

org.springframework.cloud.fn.task.launch.request.TaskLaunchRequestFunctionConfiguration

@Configuration
 @EnableConfigurationProperties(value=TaskLaunchRequestFunctionProperties.class)
public class TaskLaunchRequestFunctionConfiguration
extends Object

Configuration for a TaskLaunchRequestFunction, provided as a common function that can be composed with other Suppliers or Functions to transform any Message to a TaskLaunchRequest which may be used as input to the TaskLauncherFunction to launch a task. Command line arguments used by the task, as well as the task name itself may be statically configured or extracted from the message contents, using SpEL. See TaskLaunchRequestFunctionProperties for details. It is also possible to provide your own implementations of CommandLineArgumentsMessageMapper and TaskNameMessageMapper.
