Welcome to the world of Software Development! In this guide, we’ll take you through the key elements of creating a RESTful application using Angular for the frontend and SpringBoot for the backend. If you’re someone who loves staying in control of their code and is looking to dive into an implementation that covers both security and efficient data handling — keep reading!

Project Overview

This application is designed to demonstrate a service-oriented architecture utilizing RESTful services. We’ll leverage a robust technology stack composed of:

• Angular 5 for the frontend
• SpringBoot for the backend
• Token-based security using Spring Security and JWT
• Documentation using Swagger and ReDoc
• In-memory database using H2

Getting Started

Before we dive into building, make sure you have the following prerequisites installed:

• Java 8
• Maven 3.3.9+ or Gradle 3.3+
• Node 6.0 or above
• npm 5 or above
• Angular CLI 1.6.3

Folder Structure

Here’s how the project folder is structured:

PROJECT_FOLDER
  ├── README.md
  ├── pom.xml
  ├── build.gradle
  ├── src
  │   ├── main
  │   │   ├── java
  │   │   ├── resources
  │   │   │   ├── application.properties // Spring Boot Configurations
  │   │   │   ├── schema.sql // Database Schema Script
  │   │   │   ├── data.sql // Sample Data Script
  │   ├── public // HTML, CSS, etc.
  └── target // Build files

Think of this folder structure like a well-organized library where each section is dedicated to a specific purpose — configuration scripts in one section, business logic in another, and resources easily accessible for the user.

Building Your Application

Now, let’s get our hands dirty!

Build the Backend

To get started with the backend using Maven, navigate to the project folder and run:

mvn clean install

If you’re using Gradle, run:

gradle build

Start the API and WebUI Server

Run the server using the following command:

java -jar target/app-1.0.0.jar

Accessing Your Application

Once your server is up and running, you can access the application using the following URLs:

• Frontend: http://localhost:9119 (credentials: demo/demo)
• H2 Database Console: http://localhost:9119/h2-console
• Swagger API Documentation: http://localhost:9119/swagger-ui.html

Token-Based Security

The application uses token-based security to protect the REST API endpoints. To obtain a token, you’ll need to log in with valid credentials:

curl -X POST --header "Content-Type: application/json" \
-d '{"username":"demo", "password":"demo"}' \
http://localhost:9119/session

After receiving your token, include it in the header for all subsequent API requests:

curl -X GET --header "Authorization: xxx.xxx.xxx" http://localhost:9119/version

Troubleshooting

If you encounter issues, consider the following troubleshooting tips:

• Double-check that your server is running without errors.
• Ensure that your database credentials in data.sql are correct.
• Verify your URL endpoints for typos.
• If the Swagger UI doesn’t load, check if springfox is properly integrated.
