Storing Images in MySQL Database Using Spring Boot

In modern web applications, storing images in databases is a common practice, allowing for centralized data management and retrieval. In this tutorial, we are going to store images in a MySQL database using Spring Boot.

Storing Images in MySQL Database Using Spring Boot


Before we start, ensure you have the following prerequisites:

  1. Java Development Kit (JDK) installed on your machine.
  2. MySQL database server installed locally or remotely with appropriate access credentials.
  3. An IDE for development

Setting Up the Spring Boot Project

Create a Spring Boot Project

Let’s create our spring boot project. You can use for creating spring boot projects. Make sure that you have included all the necessary dependencies like Spring Web, Spring Data JPA, and MySQL Driver in your project.

MySQL Properties for Spring Boot

Now we have to Configure or application.yml file to set up the MySQL database connection. Replace the username and password with your MySQL database credentials

Entity Class for Storing Images

Let’s create an entity class to represent the image entity and map it to the database using JPA annotations. Here’s our entity class names FileObj .


JPA Repository

Let’s create a repository interface that extends JpaRepository to handle CRUD operations for the FileObj .

Service Layer Implementation

Let’s implement our Service class for business logic. Here we are creating two methods one for storing images to MySQL and one for fetching images from MySQL Database.

Controller Implementation

Let’s Create our controller. The ImageController is a class in our Spring Boot application that handles incoming HTTP requests related to image operations. It serves as an interface between the client (e.g., web browser, mobile app) and the backend logic responsible for managing image storage, retrieval, and other related functionalities

Testing the End-Points

Our Spring Boot Application is ready let’s run this application and test in Post-Man

Testing end points in Post-Man

That’s all for this tutorial, the entire source code is available here. Congratulations! You’ve learned how to store images in a MySQL database using Spring Boot. This tutorial provides a basic setup, and you can extend this functionality for more advanced features like image resizing, validation, or implementing additional endpoints for image manipulation. Always consider best practices and security measures when handling file uploads in a production environment.

Thanks !!!
