AWS CodeStar is a managed service from AWS that lets us quickly develop, build & deploy C#, Go, HTML, Java, Node.js, PHP, Python & Ruby apps. This article explores using CodeStar to build Spring Boot microservices.
We begin at the CodeStar home page at https://console.aws.amazon.com/codestar/home. Create a New Project & choose the Java Spring Lambda Web Service template:
Enter Project Name & ID & click Next:
Review Project Details & Create Project:
Select AWS Cloud9 as our Code Editor & click Next:
Click Next:
We now arrive at our Project Dashboard. Wait for the Cloud9 environment to finish creating. Once that’s done, we need a way to try out our brand new microservice. Add the App Endpoints tile to the Dashboard:
Open the App Endpoint in a new tab to see the output:
{
"Output": "Hello World!"
}
Let’s try changing this! To get to our code, switch to the IDE tab & click Open IDE:
In the IDE, open HelloWorldHandler.java & change “Hello World!” to “Hello World 2!”:
Do the same in HelloWorldHandlerTest.java:
Commit & Push these changes:
Wait a few minutes for the automated Build & Deployment to finish. Now reopen the App Endpoint to see the change we made:
{
"Output":"Hello World 2!"
}
This was a simple example demonstrating the power of CodeStar. The code can be further elaborated to create full-fledged microservices!
