在默认情况,如果你对 Spring Batch 不进行配置的话。
Spring Batch 将会对所有存在的作业(Job)进行执行。
考察项目:https://github.com/cwiki-us-spring/cwiki-us-spring-batch-examples 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 > Configure project : You are using one or more deprecated Asciidoctor Gradle plugin features. To help with migration run with --warning-mode=all. Repository https://jcenter.bintray.com/ replaced by https://maven.ossez.com/repository/internal. BUILD SUCCESSFUL in 10s 6 actionable tasks: 2 executed, 4 up-to-date C:\WorkDir\Repository\Spring\cwiki-us-spring-guides\cwiki-us-spring-batch-examples>
然后你可以运行
java -jar service/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 -jar service/build/libs/service.jar --spring.batch.job.enabled=true --spring.batch.job.names=cloudClean
将会执行你指定的作业。
