That’s right, you can remote debug your standalone Java applications with your favorite IDE. If we are running against a local cloud, remote debug options will also be added to JAVA_OPTS if we push or start the app with –debug. When this app is deployed, Cloud Foundry will set JAVA_OPTS to a min and max heap size based on the memory reservation we provide. The generated start script, target/appassembler/bin/demo, uses the JAVA_OPTS environment variable to pass options to Java. Enter the Maven Application Assembler Plugin. In order to run this example on Cloud Foundry, we’ll need to package up all of the dependencies.
RUN A LOCAL CLOUD FOUNDRY INSTANCE CODE
The only code in this project is a single class that activates the cloud profile and bootstraps the ApplicationContext.
The cloud profile uses the cloud namespace provided by theĬloudfoundry-runtime library to create a connection to a single Rabbit service bound to the app. The user and text from each tweet is published to an AMQP exchange named “tweets.” The connection to Rabbit is controlled by the choice of “default” or “cloud” profile. Using Spring Integration, we’ve set up an Inbound Twitter Channel Adapter to query Twitter for the word “cloud” every five seconds. mycomp:twitter2rabbit$ more src/main/resources/org/springsource/samples/twitter/context.xml In fact, all of the worker’s logic is contained in a single Spring context file. The worker app is written with Spring Integration. Mycomp:dev$ cd twitter-rabbit-socks-sample/twitter2rabbit Let’s clone the sample app from Github: mycomp:dev$ git clone The worker publishes tweet information to a RabbitMQ exchange, and the web application consumes the tweets and pushes them to the browser using SockJS. The applications communicate via a shared RabbitMQ service. Deploying the Cloud Foundry Twitter Search SampleĬloud Foundry Twitter Search includes two applications: a standalone Java application that periodically polls Twitter for tweets containing the word “cloud” and a Node.js web application that displays the results.
