我有以下实体，并且使用Liquibase loadData
@Entity
class MyEntity {
@Id
private Long id;
@Lob
@Column(name="my_text")
private String myText;
}
使用Liquibase加载样本数据，已使用以下CSV文件。
id;my_text
1;referenceToFile
和referenceToFile
This is a very large text
液体定义如下：
<changeSet id="123455-1-data" author="user">
<loadData
file="config/liquibase/data/myentity.csv"
separator=";"
tableName="myentity">
<column name="id" type="numeric"/>
<column name="my_text" type="blob"/>
</loadData>
</changeSet>
但是，当使用Hibernate加载数据时，我会得到以下错误。

然后，我遇到了这个网站http://www.solewing.org/blog/2015/08/hibernate-postgresql-and-lob-string/，它说Postgres在其他地方存储text并保留long参考。但是Liquibase似乎直接插入文本值，而不是遵守Postgres text类型。
我的问题是，我们如何使用text类型的Liquibase正确加载数据？
我过去遇到了类似的问题，我使用了clob而不是斑点，它解决了我的问题
