我正在尝试开发一个Spring CockcoreDB集群数据库使用Hibernate和PostgreSQL驱动程序的应用程序。使用Spring MVC与CockroachDB
与数据库的连接正常，并且所有表都已创建。
但是，当我启动服务器我得到这个错误

的模式很简单：用户拥有多辆。
类用户
Entity
@Table(name = "ApplicationUser")
public class User {
@Id @GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
@NotNull @Column(unique = true)
private String username;
@NotNull @Size(min = 5, max = 15)
private String password;
@NotNull
private String firstName;
@NotNull
private String lastName;
@NotNull @Column(unique = true)
private String mailAddress;
@NotNull @Column(unique = true)
private String phoneNumber;
...........
}
级车
@Entity
@Table(name = "car",
indexes = @Index(name = "owner_index", columnList = "owner_id"))
public class Car {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
private String name;
@OneToOne
private User owner;
......
}
Application.properties
spring.datasource.url = jdbc:postgresql://~~~~~~/testdb
spring.jpa.show-sql = true
spring.jpa.database = postgresql
spring.datasource.driver-class-name= org.postgresql.Driver
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
在p因为没有创建外键索引，因此Car表中的外键“所有者”似乎来自索引。
当我试图表明从车指标，我得到：
~~~~~~~~~~/testdb> show indexes from car;
+-------+---------+--------+-----+--------+-----------+---------+----------+
| Table | Name | Unique | Seq | Column | Direction | Storing | Implicit |
+-------+---------+--------+-----+--------+-----------+---------+----------+
| car | primary | true | 1 | id | ASC | false | false |
+-------+---------+--------+-----+--------+-----------+---------+----------+
我已经尝试在球场上手动创建索引owner_id，但它不工作。
