db2 as a service in Cloud foundry - db2

Question

Im trying to connect to db2 service defined in my Cloudfoundry and it is bound to my application.
#Configuration
#ServiceScan
#Profile("cloud")
public class Db2CloudConfig extends AbstractCloudConfig {
#Bean
public DataSource db2servicenew() {
CloudFactory cloudFactory = new CloudFactory();
Cloud cloud = cloudFactory.getCloud();
DB2ServiceInfo db2ServiceInfo= (DB2ServiceInfo) cloud.getServiceInfo("db2servicenew");
return cloud.getServiceConnector(db2ServiceInfo.getId(), DataSource.class, null);
}
#Bean(name = "db2JdbcTemplate")
public JdbcTemplate jdbcTemplate(DataSource db2servicenew) {
return new JdbcTemplate(db2servicenew);
}
}
I have added below 2 files in resource Path /META-INF/services
org.springframework.cloud.cloudfoundry.CloudFoundryServiceInfoCreator(File)
org.springframework.cloud.cloudfoundry.DB2ServiceInfoCreator
org.springframework.cloud.service.ServiceConnectorCreator (File)
org.springframework.cloud.service.relational.DB2DataSourceCreator

Answer 1

I think If you are creating using serviceInfo it looks for certain tags/properties in cups. You can create a data source using connectionFactory.datasource("cups service name") or define the cups correctly as mentioned in the following document http://cloud.spring.io/spring-cloud-connectors/spring-cloud-cloud-foundry-connector.html#_db2
