SpringJPA – save/retrieve Files/Images to MySQL database with @Lob annotation

In the tutorial, JavaSampleApproach will show you how to create a SpringBoot project that uses SpringJpa with @Lob annotation to save Files/Images to MySQL database.

I. Technologies

– Java 1.8
– Maven 3.6.1
– Spring Tool Suite – Version 3.9.0.RELEASE
– MySQL
– Spring Boot – 1.5.9.RELEASE

II. Goal

– We create a SpringBoot project to save files/images to MySQL database as below structure:

Spring JPA saves Files-Images to MySQL server - project structure

Create MySQL table:

Spring JPA saves Files-Images to MySQL server - mysql structure

-> Run and check results:

Spring JPA saves Files-Images to MySQL server - mysql results

Spring JPA saves Files-Images to MySQL server - retrieve files results

III. Practice

Step to do:
– Create SpringBoot project
– Create data model
– Create JPA Repository
– Implement Client to save/retrieve files/images
– Configure JPA connection & MySQL script

1. Create SpringBoot project

Using SpringToolSuite to create a SpringBoot project with dependencies:

2. Create data model

3. Create JPA Repository

4. Implement Client to save/retrieve files/images

Implement code to save/retrieve files/images from MySQL database via SpringJPA repository:

5. Configure JPA connection & MySQL script
5.1 Configure connection info

– Open application.properties file, add connection info:

5.2 MySQL script

– Implement MySQL creating table script:

IV. Sourcecode
