Java JdbcSQLSyntaxErrorException:SQL语句中的语法错误；DROP TABLE PUBLIC.PRODUCTS-[*]用户（如果存在）”；

我正在尝试编写测试并使用内存数据库。我的问题是从hibernate实体创建测试模式

我有这样的实体

@Entity
@Table(name = "users", schema = "public")
@Getter
@Setter
@NoArgsConstructor
public class User {

    @Id
    @Column(name = "user_id", updatable = false, nullable = false, unique = true)
    @GeneratedValue(generator = "UUID")
    @GenericGenerator(name = "UUID", strategy = "org.hibernate.id.UUIDGenerator")
    private UUID id;

    @Column(name = "name")
    private String name;

    @Column(name = "product")
    @ManyToMany(fetch = FetchType.LAZY, cascade = {CascadeType.ALL})
    @JoinTable(name = "products_users",
            joinColumns = {@JoinColumn(name = "user_id")},
            inverseJoinColumns = {@JoinColumn(name = "product_id")})
    private Set<Product> products;

    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd@HH:mm:ss")
    @Column(name = "created_on")
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private Date createdOn;

    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd@HH:mm:ss")
    @Column(name = "modified_on")
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private Date modifiedOn;

    public User(String name, Set<Product> products, Date createdOn, Date modifiedOn) {
        this.name = name;
        this.products = products;
        this.createdOn = createdOn;
        this.modifiedOn = modifiedOn;
    }
}


@Entity
@Table(name = "product", schema = "public")
@Getter
@Setter
@NoArgsConstructor
public class Product {

    @Id
    @Column(name = "product_id", updatable = false, nullable = false, unique = true)
    @GeneratedValue(generator = "UUID")
    @GenericGenerator(name = "UUID", strategy = "org.hibernate.id.UUIDGenerator")
    private UUID id;

    @Column(name = "name")
    private String name;

    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern="yyyy-MM-dd@HH:mm:ss")
    @Column(name = "created_on")
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private Date createdOn;

    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern="yyyy-MM-dd@HH:mm:ss")
    @Column(name = "modified_on")
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private Date modifiedOn;

    public Product(String name, Date createdOn, Date modifiedOn) {
        this.name = name;
        this.createdOn = createdOn;
        this.modifiedOn = modifiedOn;
    }
}


@Entity
@Table(name = "products_users", schema = "public")
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class ProductsUsers {

    @Id
    @Column(name = "user_id", updatable = false, nullable = false, unique = true)
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private UUID userId;

    @Column(name = "product_id")
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    private UUID productId;

}

我有

应用程序属性

在测试包中

spring.datasource.url=jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;INIT=CREATE SCHEMA IF NOT EXISTS public;MODE=PostgreSQL;DATABASE_TO_LOWER=TRUE

我有这样的例外

org.hibernate.tool.schema.spi.CommandAcceptanceException:错误 正在执行DDL“alter table”public.“products\U users”drop约束 通过JDBC语句“FK2W1YLWIYJUY67N1CR5LV5OR3”

原因：org.h2.jdbc.JdbcSQLSyntaxErrorException:表 未找到“产品和用户”；SQL语句：ALTERTABLE “公共”。“产品\用户”删除约束 “FK2W1YLWIYJUY67N1Cr5Lv5Or3”

---

嗯，“产品用户”需要被转义。SQL生成在这方面可能有一个错误，但是如果您急于继续开发，请切换到更经典和用户友好的“products\u users”name.FWIW，您的应用程序的“tests”版本中似乎没有指定Hibernate方言。properties。@Kayaman，谢谢，但我还有一个例外，h2似乎没有看到实体org.hibernate.tool.schema.spi.CommandAcceptanceException：通过JDBC语句执行DDL“alter table products_users drop constraint FKs13160e0qfdn6jmmrte6q619q”时出错，原因是：org.h2.JDBC.JdbcSQLSyntaxErrorException:未找到表“products_users”；SQL语句：alter table products_users drop约束FKs13160e0qfdn6jmmrte6q619q[42102-199]@GordThompson，它没有帮助请回复：@Kayaman-Hibernate的注释还有一个“全局引用标识符”（true/false）属性，可能有助于对象名转义。
