Creating a job

We'll create a job that will simply execute some Java code. It will be a job with only one step. The step will be a Tasklet object (a single task, as opposed to a read-process-write step, which we'll cover later). We will execute this job in two different ways in the next two recipes.

How to do it…

Create a Tasklet class, which you will use to define a step and the job:

1. Create the Task1 class implementing Tasklet:

   public class Task1 implements Tasklet {    
   
   }

2. In the Task1 class, add an execute() method with the code to be executed for the job:

   public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext)
           throws Exception {
       System.out.println("Starting job..");
   
       // ... your code
       
       System.out.println("Job done..");
       return RepeatStatus.FINISHED;
   }

3. In the configuration class, add an autowired JobBuilderFactory attribute and an autowired StepBuilderFactory attribute:

   @Autowired
   private JobBuilderFactory jobs;
   
   @Autowired
   private StepBuilderFactory...
