Configuring MySQL for Spring Boot Application

Updated on May 21st, 2018

In this post, we will discuss how to configure MySQL for Spring Boot application.We will get into details for the support provided by Spring Boot for MySQL database.



Spring Boot provides ready to use support for H2 Database.Spring Boot automatically set up in memory H2 database if it detects H2 configurations in the classpath.This is really good to start working on the development project, however, most of the enterprise projects use production level databases like MySQL, Oracle etc.

Spring Boot has support for MySQL and other popular relational databases.In this post, we will focus on configuring Spring Boot for MySQL database.


1. MySQL Database Configuration

I will not cover installing MySQL server on your machine or how to create a new database in the MySQL.For this post, I am assuming that we have already installed MySQL on your machine.Please create a new database on the MySQL server (Let’s call this new database as javadevjournal).


2. Adding MySQL Dependencies

To enable support for MySQL in our project, we need to add spring-boot-starter-data-jpa and mysql-connector-java starter in the pom.xml file.

  <!-- JPA Data (We are going to use Repositories, Entities, Hibernate, etc...) -->
  <!-- Use MySQL Connector-J -->

Spring Boot auto-configure DataSource if spring-boot-starter-data-jpa is in the classpath by reading database configurations defined in the


3. Configure MySQL Using Spring Boot Properties

By Default, Spring Boot provides database configurations for the H2 database.To use MySQL for our application, we need to override these default configurations.Once we define DB properties in the project’s file, Spring Boot will not set up default database anymore.


The property spring.jpa.hibernate.ddl-auto is for database initialization.It is good security practice that after your database is in production state, you make this none.

While setting up JPA properties, We don’t need to specify the driver or the dialect.These are detected automatically.If you want to customize these properties, feel free to add/customize using file.



These are the only configuration changes required to use MySQL with your Spring Boot application.Once you start your application, Spring Boot will use MySQL as your underlying database.



In this short post, we covered configure MySQL for Spring Boot application.We learned how to override default datasource configurations provided by Spring Boot to use MySQL as the underlying database.
