How to Store Images in a Spring Boot Application

Creating a real estate application with Spring Boot and Thymeleaf opens up exciting possibilities, especially when it comes to handling multimedia elements like images. If you're wondering how to properly manage and store images within your application, you’re in the right place. This guide outlines not just how to insert image uploads, but how to effectively display them in your application.

Understanding the Problem

When building a real estate application, properties can have multiple images associated with them—often as many as 15 to 20. Storing images effectively is crucial for performance and organization. You may be considering creating a separate table for images and linking it to your property entity via a @ ManyToOne relationship. While this is a reasonable approach, understanding how to implement this correctly in code is vital.

Solution Overview

In this guide, we’ll walk through the steps necessary for storing images in a database, uploading files, and then displaying them using Thymeleaf. We will break this down into the following sections:

Creating the Image Entity

Modifying the Add Property Method

Handling File Uploads

Displaying Images in Thymeleaf

1. Creating the Image Entity

First, we need to create an Image entity that will represent images in your database. This should have a relationship with the Property entity to reflect that each property can have multiple images.

2. Modifying the Add Property Method

Next, we need to modify the /add method in your controller to handle the image uploads. You’ll want to include an area to accept a list of images. Here's how you might modify your existing code:

Conclusion

By following these steps, you can successfully manage image uploads in a Spring Boot application tailored to the real estate sector. Always remember, while it's tempting to upload images directly to a database, referencing images using their URLs is a more efficient way to handle storage and retrieval. With this setup, you’ll be able to easily display property images and enhance the user experience in your application.

Now that you're equipped with the knowledge to store and manage images, it's time to implement these solutions and see your real estate application come to life!
