问题
- I have a running web-service application on Pivotal Cloud Foundry.
- I have added a service to it which is MySql DB and I bind it with web service application.
- My Question is how to get the data source of My Sql db with Java API Plus Cloud Foundry API in (Spring-boot).
Things I have tried:
public class Configuration {
@Configuration
@Profile("cloud")
static class CloudConfiguration {
@Bean
public DataSource dataSource() {
CloudFactory cloudFactory = new CloudFactory();
Cloud cloud = cloudFactory.getCloud();
String serviceID = cloud.getServiceID();
return cloud.getServiceConnector(serviceID, DataSource.class, null);
}
}
Method Executed:
Configuration.CloudConfiguration cloudConfiguration = new CloudConfiguration();
cloudConfiguration.dataSource();
Error I get:
I get CloudExceptionfrom this code like no suitable CloudConnector is found, the getCloud()
method throws a CloudException.
Manifest File Details:

1 Add below dependencies to your pom.xml
<dependency>
<groupId>io.pivotal.spring.cloud</groupId>
<artifactId>spring-cloud-services-starter-config-client</artifactId>
</dependency>
OR
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-spring-service-connector</artifactId>
<version>1.2.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-cloudfoundry-connector</artifactId>
<version>1.2.3.RELEASE</version>
</dependency>
2 Define datasource:
public class CloudConfig extends AbstractCloudConfig {
@Bean
public DataSource dataSource() {
DataSource dataSource = connectionFactory().dataSource();
return dataSource;
}
}
OR
public class CloudConfig extends AbstractCloudConfig {
@Bean
public DataSource inventoryDataSource() {
return connectionFactory().dataSource("mysql-db-service");
}
}
