![]() OnEmbeddedConfiguration.dataSource()] threw exception You can disable auto-configuration for certain classes by using the exclude attribute of the annotation of Spring Boot, as shown below: .BeanDefinitionStoreException:įactory method [public This will prevent Spring Boot from automatically configuring the database and there won't be any errors. Sometimes, excluding DataSourceAutoConfigution can also solve this problem, especially if you don't need a database. If you want to learn more about how auto-configuration works in Spring Boot, I suggest you go through a comprehensive Spring Boot course like Spring Boot: Efficient Development, Configuration, and Deployment on Pluralsight, which will also teach you the details behind by writing your own auto configurations. This will provide the Spring Boot auto-configuration component to configure the database for you. You can do that by adding some properties to the application.properties file with the spring.datasource prefix, as shown in the following example: = jdbc:mysql://localhost/abc Spring Boot is good at configuring in-memory databases like H2, HSQLDB, Derby, etc., and it can configure them just by adding their JAR files into the classpath, but for others, you need to give Spring Boot additional details like URL, DriverClass name, etc. 3) Due to Missing Configuration in Application.properties If you are interested, you can check out this tutorial to learn more about how to connect a Java application to a database using a MySQL database.

The general reason for this error is Spring Boot's auto-configuration, which is trying to automatically configure a DataSource for you but doesn't have enough information. In this article, we'll examine different scenarios in which this Spring Boot error comes up and what you can do to solve it. If you are using Spring Boot and getting errors like "Cannot determine embedded database driver class for database type NONE" or "Error creating a bean with name 'dataSource' defined in class path resource DataSourceAutoConfiguration," then you have come to the right place.
