如何不配置Spring Batch在默认状态中执行任务？

2025-02-15 技术教程

在默认情况，如果你对 Spring Batch 不进行配置的话。

你可以 Check out 到本地后运行：

gradlew:service:bootJar

将会对项目进行编译，程序将会输出：

C:\WorkDir\Repository\Spring\cwiki-us-spring-guides\cwiki-us-spring-batch-examples>gradlew:service:bootJar>Configureproject:YouareusingoneormoredeprecatedAsciidoctorGradlepluginfeatures.Tohelpwithmigrationrunwith--warning-mode=all.Repositoryhttps://jcenter.bintray.com/replacedbyhttps://maven.ossez.com/repository/internal.BUILDSUCCESSFULin10s6actionabletasks:2executed,4up-to-dateC:\WorkDir\Repository\Spring\cwiki-us-spring-guides\cwiki-us-spring-batch-examples>

然后你可以运行

java-jarservice/build/libs/service.jar

你会发现没有作业被执行

程序输出如下：

如果你希望有作业被默认执行的话，你需要修改你检出项目的 application.properties 文件

将参数

spring.batch.job.enabled=false

修改为 true

然后重新编译然后执行，你将会发现所有作业将会被默认执行了。

请注意，在这里我们配置了

spring.batch.job.names=cloudClean

所以默认将会执行 cloudClean 作业。

或者你可以执行运行命令：

java-jarservice/build/libs/service.jar--spring.batch.job.enabled=true--spring.batch.job.names=cloudClean

将会执行你指定的作业。
