问题
I am trying to use the S/4HANA SDK to call the CompanyCode OData VDM service but if I do this in the Cloud Foundry environment I'm getting the attached error. I have been using the SDK before but this did not happened. Can you please help me here?
Code:
public List<CompanyCode> findAll() {
try {
return compCodeService.getAllCompanyCode().execute(erp())
.stream()
.map(this::toCompCode)
.collect(Collectors.toList());
} catch (ODataException e) {
throw SapException.create(e.getMessage());
}
}
private ErpConfigContext erp(){
return new ErpConfigContext(REPLICATE_WORKFORCE);
}
public static final String REPLICATE_WORKFORCE = "REPLICATE_WORKFORCE";
Error:
[Request processing failed; nested exception is 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?] with root cause

回答1:
Can you try to make sure that the RequestContextServletFilter is picked up in your application? The RequestContextServletFilter uses the @WebFilter annotation by default.
Example for Spring Boot:
@SpringBootApplication
@ServletComponentScan( "com.sap.cloud.sdk" )
public class Application extends SpringBootServletInitializer
{
...
}
See also: https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/web/servlet/ServletComponentScan.html
EDIT: Note that when running your code in a background job (not triggered by a request), you have to wrap your code with RequestContextExecutor::execute.
