The Spring cloud dataflow documentation mentions
When executing tasks externally (i.e. command line) and you wish for Spring Cloud Data Flow to show the TaskExecutions in its UI, be sure that common datasource settings are shared among the both. By default Spring Cloud Task will use a local H2 instance and the execution will not be recorded to the database used by Spring Cloud Data Flow.
I am new to Spring cloud dataflow and spring cloud task. Can somebody help me how to setup a common datasource for both. For my development purpose I'm using the embedded H2 database. Can I use the embedded one to see task execution details in Spring Flo/Dashboard?
回答1:
A common "datasource" must be shared between Spring Cloud Data Flow (SCDF) and your Spring Cloud Task (SCT) applications in order to track and monitor task executions. If the datasource is not shared, both SCDF and SCT applications by default use a individual H2 database. And because they are on different databases, the task-executions in SCDF won't have visibility to independent execution history of SCT microservice applications.
Make sure to supply common DB properties to both. In your case, you can supply the same H2 DB properties. It is as simple as Spring Boot DB property overrides.
