问题
I have a simple Spring Batch application complying with JSR-352.
I need to deploy this as a managed Task on Spring Cloud Data Flow server. As far as I know - to be able to deploy this as a Task I need to convert this application as a Spring Boot app.
I have tried to add Spring Boot dependencies and Main class however it is not running the Batch job when I start the app.
Main Class
@SpringBootConfiguration
@EnableAutoConfiguration
@EnableBatchProcessing
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Batch File created at
META-INF/batch-jobs/myjob.xml
It works when I use JobOperator in the main class to start the job (without Spring Boot).
What am I missing to run this as a Spring Boot app?
回答1:
You're missing @EnableTask annotation. With that, your batch-job will be run as a short-lived application. In other words, the application will run as long as the business logic in your XML needs to run, and it will gracefully shut down and free-up resources.
Please clone and try out the Spring Cloud Task samples [see: BatchJobApplication]. All of them should work as-is in SCDF as well.
