I'm using the example Spring-Boot and Spring-Data for an exercise, but can not play the application, the following error occurs:

My class Cep

@Entity
public class Cep {

    @Id 
    @GeneratedValue(strategy=GenerationType.SEQUENCE)
    private Long id;

    @Column
    private String cep;

    public Cep(String cep) {
        this.cep = cep;
        validarCep(cep);
    }
    protected Cep(){

    }

My Class CepRepository

public interface CepRepository extends CrudRepository<Cep, Long>{

    List<Cep> findbyId(Long id);
}

My Class CepController

@RestController
@RequestMapping("/cep")
public class CepController {

    @Autowired
    private CepRepository repository;

    @RequestMapping("/lista")
    public String retornaListaCeps(){
        Iterable<Cep> lista = repository.findAll();
        return lista.toString();
    }

}

My Class FactoryData

@Service
public class FabricaDados {

    @Autowired
    private CepRepository repository;

    public void gravarCeps() {
        repository.save(new Cep("14233-333"));
        repository.save(new Cep("14530-000"));
        repository.save(new Cep("14020-060"));
    }

    public Iterable<Cep> listarTodos() {
        Iterable<Cep> ceps = repository.findAll();
        return ceps;
    }

and my Class Main

@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages="br.com.boot")
@EnableJpaRepositories(basePackages="br.com.boot.repository")
public class Application {

    public static void main(String[] args) {

        ApplicationContext ctx = SpringApplication.run(Application.class, args);
        FabricaDados fabrica = ctx.getBean(FabricaDados.class);

        fabrica.gravarCeps();
        System.out.println(fabrica.listarTodos());

        System.out.println("Let's inspect the beans provided by Spring Boot:");

        String[] beanNames = ctx.getBeanDefinitionNames();
        Arrays.sort(beanNames);
        for (String beanName : beanNames) {
            System.out.println(beanName);
        }
    }

}

Thanks.

People also ask

What is @configuration @EnableAutoConfiguration and @ComponentScan?

How They Differ. The main difference between these annotations is that @ComponentScan scans for Spring components while @EnableAutoConfiguration is used for auto-configuring beans present in the classpath in Spring Boot applications.

Can we use both @SpringBootApplication and @EnableAutoConfiguration?

You don't need to add it manually, spring will add it internally for you based on the annotation you provide. Actually the @SpringBootApplication annotation is equivalent to using @Configuration , @EnableAutoConfiguration and @ComponentScan with their default attributes.

What is the difference between @SpringBootApplication and @EnableAutoConfiguration annotation?

The @EnableAutoConfiguration annotation is based on @Conditional annotation of Spring 4.0 which enables conditional configuration. 7. The @SpringBootApplication annotation also provides aliases to customize the attributes of @EnableAutoConfiguration and@ComponentScan annotations.

What does @EnableAutoConfiguration do in spring boot?

Annotation Type EnableAutoConfiguration. Enable auto-configuration of the Spring Application Context, attempting to guess and configure beans that you are likely to need. Auto-configuration classes are usually applied based on your classpath and what beans you have defined. For example, if you have tomcat-embedded.

Add an

@EntityScan(basePackageClasses=br.com.boot.domain.Cep.class)

to your Application.class

You need to tell Hibernate where to find your @Entity classes. Guessing in your case this should be

@EntityScan(basePackageClasses=Cep.class)
...
public class Application {

    ...

}
