大家好，我正试图在Springboot中创建另一个项目，但什么也没有发生终端没有注意到任何问题，只是实现了与cineville数据库的链接，但在创建表之后什么也没有发生！我认为这些包裹也没有问题

电影胶片的应用


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);
    }
}

两个实体：电影和乡村

@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;
}

好的，我已经找到了答案，问题很明显是包的组织问题

我有：

com.example.demo
com.example.dao

而解决方案只是scribe=>com.example.demo.dao

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
