在启动cloud-s4-sdk-book / RequestContextServletFilter问题期间找不到租户

Question

During (local) startup of the example application cloud-s4-sdk-book in the branch 15_2_spring_boot the following exception is thrown:

16:01:38.786 [localhost-startStop-1] DEBUG com.sap.cloud.sdk.cloudplatform.servlet.RequestContextServletFilter - Filter initialization parameter factory not defined.

com.sap.cloud.sdk.cloudplatform.tenant.exception.TenantAccessException: Failed to get current tenant: no RequestContext available. Have you correctly configured a RequestContextServletFilter or have you wrapped your logic in a RequestContextExecutor when executing background tasks that are not triggered by a request?

The exception is thrown inside method "loadFactory" of class RequestContextServletFilter.

I am starting the application using mvn spring-boot:run.

What can I do the get the application started correctly?

Answer 1

This exception is expected and can usually be ignored if you are running this application locally, where no tenant is available. The application should still work, because there is a fallback in place to a tenant identifier default-tenant .

Keep in mind that you need to subscribe the default tenant before interacting with the database - do an HTTP request PUT /api/callback/tenant/default-tenant .

Please note that this exception is only being logged as a warning. If you want to clean the log, adapt the TenantIdentifierResolver class.
