spring boot无法在mysql数据库中生成表

Question

我试图从defiend JpaEntities更新数据库模式，但spring boot无法生成数据库表。日志文件：

application.properties文件：

spring.datasource.url= jdbc:mysql://localhost:3306/banque_db
spring.datasource.username= root
spring.datasource.password=
spring.datasource.driver-class-name= com.mysql.cj.jdbc.Driver
spring.jpa.hibernate.ddl-auto= update
spring.jpa.show-sql= true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

客户端实体类：

 @Entity(name="client")
public class Client implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long code;
private String name;
private String email;
@OneToMany(mappedBy = "compte")
private Collection<Compte> comptes;
// + getters and setters

Answer 1

您必须设置spring.jpa.hibernate.ddl-auto=create用于数据库创建或create-drop

请参阅文档了解更多详细信息。

Answer 2

实际上，问题是实体类不在正确的一揽子计划中。org.example中包含主类和org.entities由于某种原因，spring boot没有生成表，所以当我移动实体包变成像org.example.entities一样运行应用程序时，所有的表都成功生成了。谢谢你们的帮助，我承认：）
