Question

我正在尝试生成一个Liquibase diffChangeLog 正在获取：
Unexpected error running Liquibase: org.hibernate.MappingException: No Dialect mapping for JDBC type: 2003

问题似乎是在实体中使用数组属性。
我为此数组创建了一个休眠用户类型，因为休眠不支持数据库数组。

任何人都可以帮助运行 diffChangeLog 吗？
不知道我是否必须以任何方式配置liquibase或休眠...

（注意：Liquibase命令 generateChangeLog 运行成功）
（注2：在应用程序中读写数据库工作正常）

使用的软件：

PostgreSQL 9.6
休眠5.2.17Final
liquibase 3.5.5
春季2.0.4
spring-data 2.0.9
java 8 / kotlin 1.3.21

实体（科林）

import javax.persistence.Column
import javax.persistence.Entity
import javax.persistence.Table

import org.hibernate.annotations.Type

import com.fasterxml.jackson.databind.annotation.JsonDeserialize
import com.fasterxml.jackson.databind.annotation.JsonSerialize

@Entity
@Table(name = "my_entity")
class MyEntity : Serializable {
…

    @Column(name = "my_values")
    @JsonDeserialize(using = StringArrayDeserializer::class)
    @JsonSerialize(using = StringArraySerializer::class)
    @Type(type = "de.mycompany.mypackage.domain.json.CustomArrayType")
    var myValues: Array<String>? = null
…
}

用户类型（java）

import java.sql.Array;

public class CustomArrayType implements UserType {
    public int[] sqlTypes() {
        return new int[]{Types.ARRAY};
    }

    public Class returnedClass() {
        return String[].class;
    }
…
}

具有自定义数组的实体的库更改集

    <changeSet id="123456789-1" author="me">
        <createTable tableName="my_entity">
            …
            <column name="myValues" type="varchar() []">
                <constraints nullable="true" />
            </column>
            …
        </createTable>

    </changeSet>

通过gradle任务从命令行启动进程

gradle任务

def liquibaseCommand(command) {
    javaexec {

        main = "liquibase.integration.commandline.Main"

        def cfg = <load config from yml>

        args "--changeLogFile=src/main/resources/config/liquibase/changelog/" + buildTimestamp() +"_changelog.xml"
        args "--referenceUrl=hibernate:spring:de.mycompany.mypackage.domain?dialect=org.hibernate.dialect.PostgreSQL95Dialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy"
        args "--username=${cfg.spring.datasource.username}"
        args "--password=${cfg.spring.datasource.password}"
        args "--url=${cfg.spring.datasource.url}"
        args "--driver=org.postgresql.Driver"
        args command
    }
}

运行产生以下错误：

Liquibase diffChangeLog用于带有PostgreSQL和休眠状态的数组类型时发生MappingException
