mysql - Spring JPA doesn't create my entities on mysql
问题描述
Hello Everybody I'm trying to create another project in Springboot but nothing happen the terminal doesn't notice any problem and just achieve to link with the cineville database but nothing happen after for creating the tables ! I don't think the packages are problematic neither...
The CinevilleApplication
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
@SpringBootApplication
public class CinevilleApplication {
public static void main(String[] args) {
SpringApplication.run(CinevilleApplication.class, args);
}
}
Two entities Cinema and Ville
@Entity
@Data @AllArgsConstructor @NoArgsConstructor @ToString
public class Cinema implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
private String name;
private double longitude,latitude,altitude;
private int nombreSalles;
@OneToMany(mappedBy ="cinema")
private Collection<Salle> salles;
@ManyToOne
private Ville ville;
}
@Entity
@Data @AllArgsConstructor @NoArgsConstructor @ToString
public class Ville {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
private String name;
private double longitude,latitude,altitude;
@OneToMany(mappedBy = "ville")
private Collection<Cinema> cinemas;
}
The Application.properties file
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/cineville?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username = root
spring.datasource.password =
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = create-drop
spring.jpa.generate-ddl=true
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
server.port=9090

解决方案
好的,我找到了答案,问题显然是包裹的组织
我有:
- com.example.demo
- com.example.dao
解决方案只是 scribe => com.example.demo.dao
