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. If you want to customize these properties, feel free to add/customize using application.properties file. While setting up JPA properties, We need not specify the driver or the dialect. create-drop: Creates the database and drops it when SessionFactory closes.create: Creates the database every time but does not drop it on close.update: Hibernate changes the database according to the entity structures.We make no change to the database structure. It is good security practice that after your database is in production state, you make this none. The property -auto is for database initialization. # The SQL dialect makes Hibernate generate better SQL for the chosen database =jdbc:mysql://localhost:3306/javadevjournal Configure MySQL Using Spring Boot Propertiesīy 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 application.properties file, Spring Boot will not set up default database anymore. Spring Boot auto-configure DataSource if spring-boot-starter-data-jpa is in the class-path by reading database configurations defined in the application.properties. 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. For this post, I assume 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). I will not cover installing MySQL server on your machine or how to create a new database in the MySQL. Spring Boot has support for MySQL and other popular relational databases.In this post, we will focus on configuring Spring Boot for MySQL database. Spring Boot provides a 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 superb to work on the development project, however, most of the enterprise projects use production level databases like MySQL, Oracle, etc. Configure MySQL for Spring Boot Application We will get into details for the support provided by Spring Boot for MySQL database and steps for configuring MySQL for Spring Boot Application. You can use Spring JDBC for simple cases and Spring Data JPA for more advanced usage.In this post, we will discuss how to configure MySQL for Spring Boot application. args) throws Exception To learn more about Spring Data JPA, I recommend you to follow this article: Understand Spring Data JPA with Simple ExampleThat’s how to connect to MySQL database server in a Spring Boot application. n(MySqlConnectionApplication.class, void run(String. Import class MySqlConnectionApplication implements CommandLineRunner JdbcTemplate jdbcTemplate The following example program illustrates how to use JdbcTemplate to execute a SQL Insert statement: package net.codejava You need to declare the following dependency: Connect to MySQL with Spring JDBCSpring JDBC provides a simple API on top of JDBC ( JdbcTemplate), which you can use in simple cases, e.g. If you connect to a remote MySQL server, you need to replace localhost by IP address or hostname of the remote host.ģ. =passwordUpdate the data source URL, username and password according to your MySQL configuration. Specify Data Source PropertiesNext, you need to specify the following properties in the Spring Boot application configuration file ( application.properties): =jdbc:mysql://localhost:3306/bookshop You don’t need to specify the version as Spring Boot uses the default version specified in the parent POM. Declare dependency for MySQL JDBC DriverTo use MySQL JDBC driver, declare the following dependency in the Maven pom.xmlfile of your Spring Boot project: In case of Spring Data JPA, you need to create an entity class, a repository interface and then use the Spring Data JPA API.īelow are the details for connecting to MySQL server in a Spring Boot application.In case of Spring JDBC, use JdbcTemplate APIs for executing SQL statements against the database.Specify data source properties for the database connection information.Declare a dependency for Spring JDBC or Spring Data JPA.Declare a dependency for MySQL JDBC driver, which enables Java application to communicate with MySQL server.A Spring Boot web application with Spring Data JPA and Hibernate frameworkīasically, in order to make a connection to a MySQL server, you need to do the following steps:.A Spring Boot console application with Spring JDBC and JdbcTemplate.In this article, I’d like to share with you how to configure a Spring Boot application to connect to MySQL database server, in these two common scenarios:
