Question

我正在尝试编写测试并在内存DB中使用。我的问题是从休眠实体为测试创建架构。

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;

}

和

application.properties

spring.output.ansi.enabled=ALWAYS
server.port=8081
debug=true

spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=123
spring.datasource.driver-class-name=org.postgresql.Driver

spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.show-sql=false

我有

application.properties

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
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=

spring.jpa.hibernate.ddl-auto=create-drop
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect

spring.jpa.properties.hibernate.globally_quoted_identifiers=true
spring.jpa.properties.hibernate.default_schema=public

我得到这样的异常

org.hibernate.tool.schema.spi.CommandAcceptanceException：错误   执行DDL“更改表” public“。” products_users“删除约束   通过JDBC语句“ FK2w1ylwiyjuy67n1ycr5lv5or3”

由以下原因引起：org.h2.jdbc.JdbcSQLSyntaxErrorException：表   找不到“ products_users”； SQL语句：alter table   “ public”。“ products_users”放置约束   “ FK2w1ylwiyjuy67n1ycr5lv5or3”

JdbcSQLSyntaxErrorException：SQL语句“ DROP TABLE PUBLIC.PRODUCTS-[*] USERS IF EXISTS”
