使用HSQLDB的Spring数据JPA：用户缺少特权或找不到对象

Question

我正在尝试使用可能包含Spring Data JPA注释的文章来设置一个简单的数据库。但是，一旦我在文章Hibernate上启用了注释关系，就会引发异常：

o.h.t.s.i.ExceptionHandlerLoggedImpl     : GenerationTarget encountered exception accepting command : Error executing DDL via JDBC Statement

org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement    at org.hibernate.tool.schema.internal.exec.GenerationTargetToDatabase.accept(GenerationTargetToDatabase.java:67) ~[hibernate-core-5.2.17.Final.jar:5.2.17.Final]

... 157 common frames omitted

我的文章类如下所示：

@Entity
public class Article {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String name;
    private String abstractText;
    private String author;
    private Date createdAt;
    private int visibility;
    private int likes;
    private int views;
    private int commentCount;
    @OneToMany(cascade=CascadeType.ALL)
    private List<Comment> comments;
    // getters and setters omitted
}

和评论：

@Entity
public class Comment {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private int id;
    private String commentText;
    private Date createdAt;
}

pom包含对HSQLDB，PostgreSQL，Spring Boot Starter Data JPA和Spring Boot Starter Web的依赖关系：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.hsqldb</groupId>
    <artifactId>hsqldb</artifactId>
    <scope>runtime</scope>
</dependency>

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <scope>runtime</scope>
</dependency>

当我删除与评论列表的关系时，它就起作用了。有什么建议么？

似乎是spring.jpa.hibernate.ddl-auto财产问题。Spring默认将其create-drop用于内存数据库。但是，在当前的Spring Boot或HSQLDB或Hibernate版本（或者可能是组合？）中，这似乎会引起问题。将值更改为后update，它可以正常工作。
