Java 在spring批处理管理中加载外部配置文件

java spring spring-batch

Java 在spring批处理管理中加载外部配置文件,java,spring,spring-batch,spring-batch-admin,Java,Spring,Spring Batch,Spring Batch Admin,我在repo中下载了spring批处理管理应用程序，并在eclipse中导入了它。它工作得很好然后，我问自己如何将外部配置文件导入到我可以在作业定义类中使用的应用程序中我试过这个： VM参数 -Dspring.config.location=C:/path/to/config/file/application.properties 作业配置 src/main/java org.springframework.batch.admin.sample.job ------------------

我在repo中下载了spring批处理管理应用程序，并在eclipse中导入了它。它工作得很好

然后，我问自己如何将外部配置文件导入到我可以在作业定义类中使用的应用程序中

我试过这个：

VM参数

-Dspring.config.location=C:/path/to/config/file/application.properties
