Solace PubSub+ Spring Cloud Connectors

A Spring Cloud Connector for an instance of Solace PubSub+ in Cloud Foundry. Specifically a ServiceInfo and ServiceInfoCreator implementation for Solace PubSub+ in Cloud Foundry.



This project provides an implementation of the ServiceInfo and ServiceInfoCreator interfaces to extend the Spring Cloud Connectors project to the Solace PubSub+ Cloud Foundry service. Using this in your Spring application can make consuming the Solace PubSub+ service simpler than straight parsing of the VCAP_SERVICES environment variable.

The Spring cloud documentation provides both a nice introduction to Cloud Connectors and a nice overview of the options for extending Spring Cloud. This project provides a Cloud Service Support extension to make it easy to consume the Solace PubSub+ Cloud Foundry Service in your Cloud Foundry application. The following diagram attempts to provide an architectural overview of what is implemented in this project.


Spring Cloud connectors

This project extends Spring Cloud Connectors. If you are new to Spring Cloud Connectors, check out their project on GitHub here: https://github.com/spring-cloud/spring-cloud-connectors

The following is a brief introduction copied from their README:

Spring Cloud Connectors simplifies the process of connecting to services and gaining operating environment awareness in cloud platforms such as Cloud Foundry and Heroku, especially for Spring applications. It is designed for extensibility: you can use one of the provided cloud connectors or write one for your cloud platform, and you can use the built-in support for commonly-used services (relational databases, MongoDB, Redis, RabbitMQ) or extend Spring Cloud Connectors to work with your own services.

Java Applications

Applications can use this connector with Spring Cloud to access the information in the VCAP_SERVICES environment variable, necessary for connection to a Solace PubSub+ Service Instance.

In the following example the code finds the Solace PubSub+ Cloud Foundry service instance name MyService and uses the SolaceServiceCredentials object to connect a Solace PubSub+ API for Java (JCSMP) session.

CloudFactory cloudFactory = new CloudFactory();
Cloud cloud = cloudFactory.getCloud();
SolaceServiceCredentials solacemessaging = (SolaceServiceCredentials) cloud.getServiceInfo("MyService");

// Setting up the JCSMP Connection
final JCSMPProperties props = new JCSMPProperties();
props.setProperty(JCSMPProperties.HOST, solacemessaging.getSmfHost());
props.setProperty(JCSMPProperties.VPN_NAME, solacemessaging.getMsgVpnName());
props.setProperty(JCSMPProperties.USERNAME, solacemessaging.getClientUsername());
props.setProperty(JCSMPProperties.PASSWORD, solacemessaging.getClientPassword());

JCSMPSession session = JCSMPFactory.onlyInstance().createSession(props);

Spring Applications

The Spring Cloud Auto-Configure Java, JMS and JNDI tutorials in the Solace PubSub+ with Pivotal Cloud Foundry Getting Started Samples provide easy integration into Spring applications.

Above example for the Solace PubSub+ API for Java (JCSMP) would be further simplified as follows: here Spring creates a SpringJCSMPFactory with all the properties set and all that is required is to autowire this into your application. Check out the tutorial for further details.

private SpringJCSMPFactory solaceFactory;

JCSMPSession session = solaceFactory.createSession();
