在 Spring Boot 上运行 Spring Batch (JSR-352) 应用程序 [英] Run Spring Batch (JSR-352) application on Spring Boot

问题描述

我有一个符合 JSR-352 的简单 Spring Batch 应用程序.

I have a simple Spring Batch application complying with JSR-352.

我需要将它部署为 Spring Cloud Data Flow 服务器上的托管任务.据我所知 - 为了能够将其部署为任务，我需要将此应用程序转换为 Spring Boot 应用程序.

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.

我尝试添加 Spring Boot 依赖项和 Main 类，但是当我启动应用程序时它没有运行批处理作业.

I have tried to add Spring Boot dependencies and Main class however it is not running the Batch job when I start the app.

主类

@SpringBootConfiguration
@EnableAutoConfiguration
@EnableBatchProcessing
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

批处理文件创建于

META-INF/batch-jobs/myjob.xml

当我在主类中使用 JobOperator 来启动作业(没有 Spring Boot)时，它可以工作.

It works when I use JobOperator in the main class to start the job (without Spring Boot).

将它作为 Spring Boot 应用程序运行我缺少什么?

What am I missing to run this as a Spring Boot app?

推荐答案

您缺少 @EnableTask 注释.这样，您的批处理作业将作为短期应用程序运行.换句话说，只要您的 XML 中的业务逻辑需要运行，应用程序就会运行，并且它会优雅地关闭和释放资源.

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.

请克隆并试用 Spring Cloud 任务示例 [参见:BatchJobApplication].所有这些都应该在 SCDF 中按原样工作.

Please clone and try out the Spring Cloud Task samples [see: BatchJobApplication]. All of them should work as-is in SCDF as well.
