This sample code helps get you started with a simple Java web service deployed by AWS Elastic Beanstalk.
This sample includes:
- README.md - this file
- .ebextensions/ - this directory contains configuration files that allows AWS Elastic Beanstalk to deploy your Java service
- buildspec.yml - this file is used by AWS CodeBuild to build the web service
- pom.xml - this file is the Maven Project Object Model for the web service
- src/ - this directory contains your Java service source files
These directions assume you want to develop on your local computer, and not from the Amazon EC2 instance itself. If you're on the Amazon EC2 instance, the virtual environment is already set up for you, and you can start working on the code.
To work on the sample code, you'll need to clone your project's repository to your local computer. If you haven't, do that first. You can find instructions in the AWS CodeStar user guide.
-
Install maven. See https://maven.apache.org/install.html for details.
-
Install tomcat. See https://tomcat.apache.org/tomcat-7.0-doc/setup.html for details.
-
Build the service.
$ mvn -f pom.xml compile $ mvn -f pom.xml package -
Copy the built service to the Tomcat webapp directory. The actual location of that directory will vary depending on your platform and installation.
$ cp target/ROOT.war <tomcat webapp directory> -
Restart your tomcat server
-
Open http://127.0.0.1:8080/ in a web browser to view your service.
Once you have a virtual environment running, you can start making changes to the sample Java web service. We suggest making a small change to /src/main/java/com/aws/codestar/projecttemplates/controller/HelloWorldController.java first, so you can see how changes pushed to your project's repository are automatically picked up and deployed to the Amazon EC2 instance by AWS Elastic Beanstalk. (You can watch the progress on your project dashboard.) Once you've seen how that works, start developing your own code, and have fun!
