Class TaskletStep

java.lang.Object
  org.springframework.batch.core.step.AbstractStep
      org.springframework.batch.core.step.tasklet.TaskletStep

All Implemented Interfaces:

Step, BeanNameAware, InitializingBean

public class TaskletStep
extends AbstractStep

A Step that executes a Tasklet directly. This step does not manage transactions or any looping functionality. The tasklet should do this on its own. If the Tasklet itself implements StepExecutionListener it will be registered automatically, but its injected dependencies will not be. This is a good way to get access to job parameters and execution context if the tasklet is parameterized.
