Spring Boot - JPA - Postgres ERROR: cross-database references are not implemented:

Question

我正在使用 Spring Boot、JPA 和 Postgres，并且我有一个具有多个模式的数据库。我使用 JPA 实现 Web 服务，但收到此错误：

o.h.engine.jdbc.spi.SqlExceptionHelper：错误：未实现跨数据库引用："kaloudia_db_v2.enumeration.unit"

你知道克服这个错误的方法吗？

我的 class 是

@Entity
@Table(name = "unit", schema = "enumeration", catalog = kaloudia_db_v2")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "Unit.findAll", query = "SELECT u FROM Unit u"),
    @NamedQuery(name = "Unit.findById", query = "SELECT u FROM Unit u WHERE u.id = :id"),
    @NamedQuery(name = "Unit.findByNameEn", query = "SELECT u FROM Unit u WHERE u.nameEn = :nameEn"),
    @NamedQuery(name = "Unit.findByNameEl", query = "SELECT u FROM Unit u WHERE u.nameEl = :nameEl")})
public class Unit implements Serializable {
private static final long serialVersionUID = 1L;
@Id

JPA函数的调用是：

public Object getAllUnits() {
    List<Unit> units = unitRepository.findAll();
    return units;
}

正如杰克所说，我看到了应用程序属性文件，我发现我忘记更改 spring.datasource.url 属性!!

很抱歉我的问题！现在可以正常使用了！
