No suitable ServiceConnectorCreator found error - Spring cloud/CloudFoundry

Question

All,

I have a spring boot app that gives me an error, when I try to push to IBM Bluemix/CloudFoundry.

This is a spring boot app, using spring cloud and trying to connect to a relational db service (sqldb which is a cloud version of DB2) service.

I could connect without spring cloud, where I explicitly specified the db credentials from vcap_services in my property file. However I am trying to avoid that using spring cloud abstraction, but gets the error mentioned below.

My expectation is the spring boot/cloud should identify the test-sqldb service I bound to the app and create a data source on the fly. Instead I get the error given below when I do cf push.

Is it fair to assume that spring boot/cloud pair will orchestrate the data source for me as I have the db2 driver jar and attached service in environment.? If not, can some one point to me what am I missing?

I have following config in spring context file as given below as mentioned in this link. Using the cloud profile to separate from my local datasource config.

spring config - this is imported to my spring context and is in effect when I run with cloud profile

<beans profile="cloud">
    <cloud:data-source id="dataSourcePref" service-name="test-sqldb">
        <!-- <cloud:pool-data-sources>
            <value>TomcatJdbc</value>
            <value>TomcatDbcp</value>
            <value>BasicDbcp</value>
        </cloud:pool-data-sources>-->
    </cloud:data-source>
</beans>    

Spring Boot Application Class

@SpringBootApplication
@ImportResource("classpath:/META-INF/spring/my-jpa-beans.xml")
public class JpaTestApplication {

    public static void main(String[] args) {
       SpringApplication.run(JpaTestApplication.class, args);
    }
 }

Answer 1

Seems I understood what is happening.

An answer in this thread mentions about Service connectors that gave me a hint.

SqlDb need DB2DataSourceCreator which was not available in spring-cloud-connectors version 1.1.1-release, which I was using. It supports others like MySQL, Postgres, Redis, MongoDB, RabbitMQ, etc..

Upgraded to 1.2.0-release and I am able to pass this error point. Thanks for two of you who tried to help.
