Minimal Spring Boot sample app.

Requirements

For building and running the application you need:

• JDK 1.8
• Maven 3

Running the application locally

There are several ways to run a Spring Boot application on your local machine. One way is to execute the main method in the de.codecentric.springbootsample.Application class from your IDE.

Alternatively you can use the Spring Boot Maven plugin like so:

mvn spring-boot:run

Deploying the application to OpenShift

The easiest way to deploy the sample application to OpenShift is to use the OpenShift CLI:

oc new-app codecentric/springboot-maven3-centos~https://github.com/codecentric/springboot-sample-app

This will create:

• An ImageStream called "springboot-maven3-centos"
• An ImageStream called "springboot-sample-app"
• A BuildConfig called "springboot-sample-app"
• DeploymentConfig called "springboot-sample-app"
• Service called "springboot-sample-app"

If you want to access the app from outside your OpenShift installation, you have to expose the springboot-sample-app service:

oc expose springboot-sample-app --hostname=www.example.com

--->
Single page website to store, update, delete employee information from the database.

--->
Here for the frontend, I use Angular, and Spring Boot as the backend and MySQL for the database.

--->
In my backend API, I have a model or entity to hold the employee attributes. Have a repository to access the database, extended by JpaRepository. And, service to implements all the business logic to manage the employee operations. A controller to maps requests and handles them and calls the service if needed. For the database, MySQL database has been used and connected with the backend through the application.properties.

--->
I have checked the HTTP requests on this API with Postman.

--->
In the Angular part, also have a model which holds the employee attributes. Have service to connect the angular app with backend controller, here I use HttpClientModule and Observable. And the component for the business logic and handle the user requests by the UI.

--->
Here I learned about the Cross-origin concept.
