Creating Real-Time Data Analytics with Spring Boot and Spring AI

In the era of big data, the ability to analyze and visualize real-time data is critical for businesses seeking a competitive edge. Whether you’re tracking customer interactions, monitoring IoT devices, or analyzing financial transactions, having the right tools to process and visualize data can make a significant difference in decision-making. In this blog post, we’ll explore how to leverage Spring Boot combined with Spring AI to create a robust real-time data analytics application.

Understanding the Tech Stack

Before we dive into the implementation, let’s quickly discuss the technologies involved:

  • Spring Boot: A powerful framework for building Java applications easily and quickly. It simplifies the setup of new applications with minimal configuration requirements.
  • Spring AI: A relatively new component of the Spring ecosystem that integrates artificial intelligence and machine learning capabilities into Spring applications.
  • WebSocket: A protocol for full-duplex communication channels over a single TCP connection, ideal for real-time data transfer.
  • Data Visualization Libraries: Libraries like Chart.js or D3.js are commonly used to create compelling visual representations of your data.

Getting Started with Your Project

Step 1: Setting Up the Spring Boot Application

Head over to Spring Initializr and set up a new project with the following dependencies:

  • Spring Web
  • Spring AI
  • Spring Data JPA (for database interactions)
  • H2 Database (for a lightweight, in-memory database)

Once you’ve generated the project, import it into your favorite IDE.

Step 2: Configuring WebSocket for Real-Time Communication

To enable real-time updates, we will use Spring WebSocket. First, we need to add the dependency in our pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

Next, create a configuration class to enable WebSocket support:

import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
    
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/data").withSockJS(); // endpoint for WebSocket connection
    }
    
    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic"); // configure message broker
        config.setApplicationDestinationPrefixes("/app");
    }
}

Step 3: Creating a Data Model and Repository

For demonstration purposes, let’s assume we’re analyzing sales data. Create a simple Sale entity:

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Sale {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String product;
    private int quantity;
    private double price;

    // Getters and setters
}

Next, create a repository interface for data access:

import org.springframework.data.jpa.repository.JpaRepository;

public interface SaleRepository extends JpaRepository<Sale, Long> {
}

Step 4: Implementing Data Processing Logic

We’ll process incoming sale data and publish updates to the WebSocket channel. Create a service for this purpose:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.stereotype.Service;

@Service
public class SaleService {
    
    private final SaleRepository saleRepository;
    private final SimpMessagingTemplate messagingTemplate;

    @Autowired
    public SaleService(SaleRepository saleRepository, SimpMessagingTemplate messagingTemplate) {
        this.saleRepository = saleRepository;
        this.messagingTemplate = messagingTemplate;
    }

    public Sale recordSale(Sale sale) {
        Sale savedSale = saleRepository.save(sale);
        messagingTemplate.convertAndSend("/topic/sales", savedSale); // publish to WebSocket
        return savedSale;
    }
}

Step 5: Creating a REST Controller

To accept incoming sale data via an HTTP POST request, set up a REST controller:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/api")
public class SaleController {

    private final SaleService saleService;

    @Autowired
    public SaleController(SaleService saleService) {
        this.saleService = saleService;
    }

    @PostMapping("/sales")
    public Sale createSale(@RequestBody Sale sale) {
        return saleService.recordSale(sale);
    }
}

Step 6: Client-Side Visualization

You can use a simple HTML page combined with JavaScript and Chart.js to visualize the data in real-time. Here’s a foundational structure for the client-side code:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <script src="https://cdnjs.cloudflare.com/ajax/libs/sockjs-client/1.5.0/sockjs.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/stomp.js/2.3.3/stomp.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
    <title>Real-Time Sales Data</title>
</head>
<body>
    <canvas id="salesChart"></canvas>
    <script>
        var socket = new SockJS('/data');
        var stompClient = Stomp.over(socket);
        var salesData = [];

        stompClient.connect({}, function (frame) {
            console.log('Connected: ' + frame);
            stompClient.subscribe("/topic/sales", function (data) {
                updateChart(JSON.parse(data.body));
            });
        });

        function updateChart(sale) {
            salesData.push(sale);
            // Logic for updating your Chart.js chart
        }
    </script>
</body>
</html>
