苦于外键约束

问题描述

定义某些外键确实有问题。 我有一个发行人，有一个地址。 我有一个国家/地区的地址。

我正在尝试使用这些POJO上的liquibse定义我的外键约束，但是没有运气，仍然是相同的错误：

cannot be applied to (Class[_$1],String) ConfluentRegistryAvroDeserializationSchema.forSpecific(

这是我的课程

如果有人遇到相同的问题，或者在这里看到可怕的东西，请不要犹豫！

解决方法

首先，您在ADDRESS表中没有列名COUNTRY_ID，但您仍在尝试使用此列创建外键

    <addForeignKeyConstraint baseTableName="ADDRESS" baseColumnNames="COUNTRY_ID"
                             constraintName="FK_ADDRESS_TO_COUNTRY" 
    referencedTableName="COUNTRY"
                             referencedColumnNames="ID"/>

将基本列名称从COUNTRY_ID更改为ID
