If you configure your own EntityManagerFactory Bean or if you have copy-pasted such a persistence configuration from another project  you must set or adapt the package in EntityManagerFactory s configuration   Bean public EntityManagerFactory entityManagerFactory   throws PropertyVetoException       HibernateJpaVendorAdapter vendorAdapter   new HibernateJpaVendorAdapter        vendorAdapter setGenerateDdl true       LocalContainerEntityManagerFactoryBean factory      factory   new LocalContainerEntityManagerFactoryBean        factory setPackagesToScan  quot       package path to entities      quot

You either missed  Entity on class definition or you have explicit component scan path and this path does not contain your class

never forget to add   Entity on domain class

You can use  EntityScan annotation and provide your entity package for scanning all your jpa entities  You can use this annotation on your base application class where you have used  SpringBootApplication annotation   e g   EntityScan  com test springboot demo entity

I think replacing  ComponentScan with  ComponentScan  com nervy dialer domain   will work   Edit    I have added a sample application to demonstrate how to set up a pooled datasource connection with BoneCP    The application has the same structure with yours  I hope this will help you to resolve your configuration problems

Configure the location of entities using  EntityScan in Spring Boot entry point class   Update on Sept 2016  For Spring Boot 1 4   use org springframework boot autoconfigure domain EntityScan instead of org springframework boot orm jpa EntityScan  as    boot orm jpa EntityScan is deprecated as of Spring Boot 1 4

I had this same problem but only when running spring boot tests cases that required JPA  The end result was that our own jpa test configuration was initializing an EntityManagerFactory and setting the packages to scan  This evidently will override the EntityScan parameters if you are setting it manually       final LocalContainerEntityManagerFactoryBean factory   new LocalContainerEntityManagerFactoryBean        factory setJpaVendorAdapter  vendorAdapter        factory setPackagesToScan  Project class getPackage   getName         factory setDataSource  dataSource      Important to note  if you are still stuck you should set a break point in the org springframework orm jpa persistenceunit DefaultPersistenceUnitManager on the setPackagesToScan   method and take a look at where this is being called and what packages are being passed to it

I got this error because I stupidly wrote     public interface FooBarRepository extends CrudRepository lt FooBarRepository  Long gt          A brief explanation   One typically creates a FooBarRepository class to manage FooBar objects  often representing data in a table called something like foo bar    When extending the CrudRepository to create the specialized repository class  one needs to specify the type that s being managed -- in this case  FooBar   What I mistakenly typed  though  was FooBarRepository rather than FooBar   FooBarRepository is not the type  the class  I m trying to manage with the FooBarRepository   Therefore  the compiler issues this error     I highlighted the mistaken bit of typing in bold   Delete the highlighted word Repository in my example and the code compiles
