Now that I look closer  I think that the DataSource problem is a red-herring  Boot s Hibernate auto-configuration is being triggered and that s what causing a DataSource to be required  Hibernate s on the classpath because you ve got a dependency on spring-boot-starter-data-jpa which pulls in hibernate-entitymanager   Update your spring-boot-starter-data-jpa dependency to exclude Hibernate    lt dependency gt       lt groupId gt org springframework boot lt  groupId gt       lt artifactId gt spring-boot-starter-data-jpa lt  artifactId gt       lt exclusions gt           lt exclusion gt               lt groupId gt org hibernate lt  groupId gt               lt artifactId gt hibernate-entitymanager lt  artifactId gt           lt  exclusion gt       lt  exclusions gt   lt  dependency gt

This is how I resolved this problem   In my case  I had to configure the datasource for MySQL Server  which was an external Server    As we all know  Spring boot has capability to auto-configure DataSource for embedded databases   Thus  I realized that I had to disable datasource auto-configuration in order use my custom configuration   As mentioned above by many  I disabled Automatic DataSource configuration of Spring Boot at application properties     spring autoconfigure exclude org springframework boot autoconfigure jdbc DataSourceAutoConfiguration   I defined all hibernate configuration properties in a separate file   hibernate-mysql properties  Then  I coded my own Custom Hibernate Configuration in following manner and it resolved the issue    My way to configure the desired DataSource based on properties in a custom property file and populate your LocalSessionFactoryBean with your data source and other hibernate configuration    Hibernate Custom Configuration Class - ---------------------------------------------------------   Hibernate Custom Configuration

Answer is very simple  SpringBoot will look for Embeddable database driver  If you didn t configure in any of your configuration in form of XML or Annotations  it will throws this exception  Make the changes in your annotation like this  EnableAutoConfiguration exclude DataSourceAutoConfiguration class  this will exclude the DataSourceAutoConfiguration  And the Perfect Simple Coding completion would be work if you have properly configured your class        Controller      EnableAutoConfiguration exclude DataSourceAutoConfiguration class       public class SimpleController          RequestMapping             ResponseBody        String home             return  Hello World            public static void main String   args  throws Exception           SpringApplication run SimpleController class  args

User · Answer

You haven t provided Spring Boot with enough information to auto-configure a DataSource  To do so  you ll need to add some properties to application properties with the spring datasource prefix  Take a look at DataSourceProperties to see all of the properties that you can set    You ll need to provide the appropriate url and driver class name   spring datasource url       spring datasource driver-class-name

You can download the derby-10 10 1 1 jar from the Maven Repository and place it in your WEB-INF lib folder  like this Application WEB-INF lib derby-10 10 1 1 jar  Your embedded AnnotationConfigEmbeddedWebApplicationContext will pickup the database driver and your webserver will start running without any issues  -

Generally  such error occurs when you ve used JPA and forget to add database connection  So  you must add database related dependencies in your application    Though  you want to use JPA without connecting any external database then add hsqldb in your dependency   I hope this helps

If you want to use embedded H2 database from Spring Boot starter add the below dependency to your pom file        lt dependency gt           lt groupId gt com h2database lt  groupId gt           lt artifactId gt h2 lt  artifactId gt           lt version gt 1 3 156 lt  version gt       lt  dependency gt    But as mentioned in comments  the embedded H2 database keeps data in memory and doesn t stores it permanently

User · Answer

From the Spring manual   Spring Boot can auto-configure embedded H2  HSQL  and Derby databases  You don   t need to provide any connection URLs  simply include a build dependency to the embedded database that you want to use  For example  typical POM dependencies would be    lt dependency gt       lt groupId gt org springframework boot lt  groupId gt       lt artifactId gt spring-boot-starter-data-jpa lt  artifactId gt   lt  dependency gt   lt dependency gt       lt groupId gt org hsqldb lt  groupId gt       lt artifactId gt hsqldb lt  artifactId gt       lt scope gt runtime lt  scope gt   lt  dependency gt   For me leaving out the spring-boot-starter-data-jpa dependency and just using the spring-boot-starter-jdbc dependency worked like a charm  as long as I had h2  or hsqldb  included as dependencies
