Spring Data JPA 异常：数据库中已经有一个名为“disease_view”的对象答案

【问题标题】：Spring Data JPA exception: There is already an object named 'disease_view' in the databaseSpring Data JPA 异常：数据库中已经有一个名为“disease_view”的对象
【发布时间】：2020-07-02 01:19:26
【问题描述】：

我有使用 SQL 服务器数据库的 Spring Boot，Spring Data 项目。在 SQL Server 中，我创建了两种类型的视图

使用 SQL 服务器表创建的视图
使用 Oracle 数据库视图创建的视图（通过 ODBC 连接）

CREATE  VIEW [dbo].[DISEASE_VIEW] AS select * from OPENQUERY([ORALCEDBLINK] , 'select * from DISEASE_VIEW')

对于本地 SQL 视图，我没有看到任何问题并且能够使用 Spring Data 访问数据。但是连接到 Oracle 数据库的视图在应用程序启动时出现异常com.microsoft.sqlserver.jdbc.SQLServerException：数据库中已经有一个名为“disease_view”的对象。。但是，我可以使用 Spring Data 存储库接口访问数据而没有任何问题。有没有人遇到过类似的问题？

@Data
@Entity
@Immutable
@Table(name = "DISEASE_VIEW")
public class DiseaseView implements Serializable
{
    private static final long serialVersionUID = -508332818333665437L;

    @Id
    @Column(name = "DISEASE_CODE")
    private String diseaseCode;

    @Column(name = "DISEASE_NAME")
    private String diseaseName;
}

这里是异常日志：

【问题讨论】：

由于您处于数据库优先环境中，您是否在数据库初始化代码中应用了spring.jpa.hibernate.ddl-auto = none;？参考：Database Initialization
@AlwaysLearning：不。实际上我设置spring.jpa.hibernate.ddl-auto = update 以在实体更改时创建新字段。每当 Spring Data 找到一个视图时，它不应该尝试使用该名称创建新表

标签： sql-server spring spring-boot spring-data-jpa spring-data

【解决方案1】：

好的。这看起来像 Hibernate 中的一个错误。我在 Hibernate JIRA 项目中创建了一个bug report。同时这里有两个我发现的选择

使用@Subselect注解并指定SELECT语句而不是Table注解

    @Data
    @Entity
    @Immutable
    @Subselect("SELECT * FROM DISEASE_VIEW")
    public class DiseaseView implements Serializable
    {
        private static final long serialVersionUID = -508332818333665437L;
        @Id
        @Column(name = "DISEASE_CODE")
        private String diseaseCode;

        @Column(name = "DISEASE_NAME")
        private String diseaseName;
    }

按照@AlwaysLearning 的建议，在第一次运行应用程序后禁用表生成 spring.jpa.hibernate.ddl-auto = none;

我会在收到 Hibernate 团队的回复后立即更新答案。
