我班切普
@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(){
}
我的班級CepRepository
public interface CepRepository extends CrudRepository<Cep, Long>{
List<Cep> findbyId(Long id);
}
我的線人屁股CepController
@RestController
@RequestMapping("/cep")
public class CepController {
@Autowired
private CepRepository repository;
@RequestMapping("/lista")
public String retornaListaCeps(){
Iterable<Cep> lista = repository.findAll();
return lista.toString();
}
}
我的班級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;
}
和我的課主要
@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);
}
}
}
感謝。
