Попытка сохранить объект в базе данных Postgresql безуспешно (без исключения)

2 голосов
/ 07 марта 2020

Я пытаюсь сохранить объект в Postgresql базе данных, но безуспешно. Приложение запускается нормально, исключение не выдается, и companiesRepository не имеет значение null. База данных была создана вручную.

Это мой Application.class : 

@SpringBootApplication
public class Application {

public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
}
}

Это мой Service.class : 

@org.springframework.stereotype.Service
public class Service {

    @Autowired
    CompaniesRepository companiesRepository;

    public void start() {
        Companies companies = new Companies();
        companies.setSomeString("some");
        companies.setId(1);

        companiesRepository.save(companies);

        log.info("Companies saved in DB");
}
}

Это мой Companies.class : 

@Entity
@Data
public class Companies {

    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Id
    Integer id;

    String someString;
}

Это мой CompaniesRepository интерфейс: 

@Repository
public interface CompaniesRepository extends CrudRepository<Companies, Integer> {

}

Это мой Controller.class : 

@RestController
public class Controller {

@Autowired
private Service service;

    @RequestMapping("/")
    public String start() throws Exception {
        service.start();
        return "App Started";
    }
}

Конфигурация, которая у меня есть в bootstrap .yaml файле, работает правильно в другом проекте: 

spring:
  jpa:
    database-platform: org.hibernate.dialect.PostgreSQLDialect
    show-sql: false
    generate-ddl: true
    time_zone: UTC
    hibernate:
      ddl-auto: update
    properties:
      hibernate:
        dialect: org.hibernate.dialect.PostgreSQLDialect 
        hbm2ddl:
          auto: update 
        jdbc:
          lob:
            non_contextual_creation: true
        enable_lazy_load_no_trans: true
  datasource:
    url: jdbc:postgresql://localhost:5432/dos?createDatabaseIfNotExist=true&serverTimezone=UTC
    driver-class-name: org.postgresql.Driver
    username: "postgres"
    password: "123"
    initialization-mode: always

hibernate:
   dialect: org.hibernate.dialect.PostgreSQLDialect
   jdbc:
     time_zone: UTC

Я пытался:

  • annottate String и id в Companies.class с @Column(nullable = false),
  • изменил имя таблицы для Companies.class с @Table(name = "some_table").
  • добавить @Autowired CompaniesRepository repository; в Controller.class

Я удалил зависимость h2.database и добавил: 

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-config</artifactId>
    <version>2.0.2.RELEASE</version>
</dependency>

И добавил в bootstrap .yaml : 

spring:
  main:
    allow-bean-definition-overriding: true

А теперь это отлично работает.
