Spring boot - Not a managed type

Solution 1:

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

Solution 2:

Try adding All the following, In my application it is working fine with tomcat

 @EnableJpaRepositories("my.package.base.*")
 @ComponentScan(basePackages = { "my.package.base.*" })
 @EntityScan("my.package.base.*")   

I am using spring boot, and when i am using embedded tomcat it was working fine with out @EntityScan("my.package.base.*") but when I tried to deploy the app to an external tomcat I got not a managed type error for my entity.

Extra read:

@ComponentScan is used for scanning all your components those are marked as @Controller, @Service, @Repository, @Component etc…

where as @EntityScan is used to scan all your Entities those are marked @Entity for any configured JPA in your application.

Solution 3:

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

Solution 4:

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("!!!!!!package.path.to.entities!!!!!");
    //...
}

Be careful of the "multiple" needs, you need a String array as the argument passed to setPackagesToScan (and NOT a comma-separated-single-string value). Below illustrates the issue.

    String[] packagesArray = "com.mypackage1,com.mypackage2".split(",");
    em.setPackagesToScan(packagesArray);
