我正在尝试使用 Hibernate 和 PostgreSQL 驱动程序开发一个类似于 CockroachDB Cluster 数据库的 Spring MVC 应用程序。
与数据库的连接正常，所有表均已创建。
但是当我启动服务器时出现此错误

该架构很简单:用户拥有多辆汽车。
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;
...........
}
等级车
@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;
......
}
应用程序属性
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
问题似乎来自 Car 表中外键“owner”的索引，因为未创建外键索引。
当我尝试显示 Car 的索引时，我得到:
~~~~~~~~~~/testdb> show indexes from car;
+-------+---------+--------+-----+--------+-----------+---------+----------+
| Table | Name | Unique | Seq | Column | Direction | Storing | Implicit |
+-------+---------+--------+-----+--------+-----------+---------+----------+
| car | primary | true | 1 | id | ASC | false | false |
+-------+---------+--------+-----+--------+-----------+---------+----------+
我已经尝试在字段owner_id上手动创建索引，但它不起作用。
最佳答案
CockroachDB 目前不支持 Hibernate 使用的所有 SQL 功能。
查看失败的查询，问题在于访问 (i.keys).n，其中 key 来自 information_schema._pg_expandarray(i.indkey)。
我们正在跟踪 CockroachDB 中对 Hibernate 的支持 here对跟踪的 _pg_expandarray 提供更具体的支持 here .
关于java - 将 Spring MVC 与 CockroachDB 结合使用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47617283/
