Stock Market Data Application

This application retrieves historical stock market data for a given stock symbol from Alpha Vantage using their API. It supports different time intervals such as intraday, daily, weekly, and monthly.

Features

• Data Retrieval: Fetches historical stock data based on user-specified intervals (intraday, daily, etc.).
• API Integration: Utilizes Alpha Vantage API for data retrieval.
• Concurrency: Supports concurrent data fetching using multiple threads.
• Simple Client: A Java-based client application that makes HTTP GET requests to the backend.

Project Structure

Backend (Spring Boot)

The backend server is built using Spring Boot and provides RESTful APIs for fetching stock data.

Main Components

1. StockService.java:

   • Service class responsible for constructing the API URL and making HTTP GET requests to Alpha Vantage.

2. StockController.java:

   • REST controller that handles incoming requests for fetching stock data based on different intervals.

3. WebServiceArswApplication.java:

   • The main class for bootstrapping the Spring Boot application.

Client (Java)

The Java client application interacts with the backend to fetch and display stock data.

Main Classes

1. StockClient.java:

   • A simple Java client that makes HTTP GET requests to the Spring Boot backend.
   • Retrieves stock data for predefined intervals and prints the response to the console.

2. StockClientTest.java:

   • A test class that executes the StockClient concurrently using multiple threads.
   • Demonstrates how to fetch stock data in parallel to improve performance.

Installation and Setup

Prerequisites

• Java Development Kit (JDK) 8 or higher
• Apache Maven

Installation Steps

1. Clone the Repository:

   git clone https://github.com/JohannBulls/WebServiceARSW
   cd WebServiceARSW

2. Compile and Run the Backend:

   mvn clean package
   mvn spring-boot:run

3. Run the Client:

   mvn clean package
   mvn exec:java -Dexec.mainClass="edu.escuelaing.arsw.ASE.app.WebServiceARSW.StockClient"

4. Access the Application:

   • The client application will fetch data from the backend based on predefined intervals and display it in the console.
