Spring数据流Kubernetes JDBC驱动程序

Question

I'm trying to deploy an jdbc-sink to a Helm based Kuberentes install of Spring Cloud Data Flow.

How would I go about adding JDBC jars in order to make use of the starters? I'm getting the following error when trying to deploy the app (in this case MySQL):

***************************
APPLICATION FAILED TO START
***************************
 Description:
 Failed to bind properties under '' to com.zaxxer.hikari.HikariDataSource:
     Property: driverclassname
    Value: com.mysql.cj.jdbc.Driver
    Origin: "driverClassName" from property source "source"
    Reason: Failed to load driver class com.mysql.cj.jdbc.Driver in either of HikariConfig class loader or Thread context classloader

Would I need to extend the existing starter, and manually add the Driver as there's no way of guaranteeing which driver it should be using?

Thanks!

Answer 1

We ship the OSS license-friendly drivers for few databases in SCDF and the app-starters that require database access, including the jdbc applications.

For proprietary drivers, there's a procedure to patch the out-of-the-box app-starters that we maintain and ship — more details in the reference guide here .

Once when you bundle the relevant driver in the classpath, you'd produce a docker image to then use it in SCDF.
