Question

我们正尝试使用Oracle数据库从Spring云数据流（1.2.3.RELEASE）执行组合任务，以存储任务/作业的状态。当我运行单个任务或作业时，它可以顺利运行而不会出现任何错误。要运行文档中指定的对象任务，我已在SCDF中注册了compos-task-runner（1.1.0.RELEASE）作为应用程序。但是当我从SCDF启动组合任务时，它无法启动具有以下错误的组合任务运行程序：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.batch.core.configuration.annotation.SimpleBatchConfiguration': Unsatisfied dependency expressed through field 'dataSources'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.tomcat.jdbc.pool.DataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Cannot load driver class: oracle.jdbc.driver.OracleDriver

即使我已经尝试在spring-cloud-starter-task-composedtaskrunner / pom中添加oracle依赖，就像我们在SCDF中使用它以使其与Oracle一起工作但它再次给出相同的错误。请在下面找到生成的pom文件：

任何人都可以帮助我理解我错过或需要添加的内容以使其正常工作。

不清楚您是如何尝试从帖子描述/ pom添加Oracle驱动程序的。如果没有在类路径中，它将失败，发现驱动程序未找到错误。

我们为应用程序提供了修补程序。与stream-apps类似，您可以下载编译任务运行程序，使用您的专有Oracle驱动程序依赖项调整pom.xml，最后使用ComposedRunnerVisitorConfiguration调整@Import。

这样你就可以build the App - 验证超级jar确认Oracle驱动程序在类路径中。您还可以在本地运行App（java -jar ..）以确保它启动并连接到所需的Oracle DB。如果它是独立运行的，它也会在从SCDF编排时运行。

另一件事。请确保CTR，SCDF与CTR图中包含的任务之间的datasource配置相同。除非他们共享相同的数据源，否则您无法在SCDF仪表板中可视化执行 - 请参阅文档here。

使用oracle数据库
