mysql - 将枚举列表保存到MySql时，Spring Data JDBC SQLFeatureNotSupportedException

标签 mysql spring kotlin spring-data spring-data-jdbc

我有一个名为Role的模型。 role具有Permission的列表，就这么简单。

使用org.springframework.boot:2.2.5.RELEASE，spring-jdbc版本5.2.24，mysql-connector-java-8.0.19，mysql服务器版本5.7.28

您也可以 checkout https://github.com/tirbison/spring-data-jdbc-kotlin/tree/bug/mysql-list-of-enum来重现该错误，不要忘记更改mysql凭据。

角色

package com.example.demo.domain.model

import org.springframework.data.annotation.Id

class Role(
        val name: String,
        val permissions: List<Permission> = emptyList()
) {
    @Id
    var id: Long? = null
}

enum class Permission {
    READ, WRITE, EXECUTE
}

图式
create table role
(
    id          serial primary key,
    name        varchar(256),
    permissions varchar(256)
);

我没有简单的权限单独表，因为我找不到使用spring-data-jdbc 将enum集合保存到表的方法，它可能是一个单独的表或不太重要的列。

当我在内存数据库中使用H2时，没有任何异常，H2将枚举以逗号分隔的形式保存到列中。但是，当我使用MySql时，出现以下异常堆栈跟踪:

最佳答案

Spring Data JDBC当前支持持久列表的两种变体。

当内容是实体时，它将存储在单独的表中。

当内容是简单类型时，如果数据库支持，它将被存储在数组中。

由于MySql不支持数组，因此您只能使用第一个变量。
但是Enum是简单的类型(即它们可以直接存储在列中)。

解决方案是将枚举包装为实体类型，即具有包含枚举的单个属性的简单类型。

关于mysql - 将枚举列表保存到MySql时，Spring Data JDBC SQLFeatureNotSupportedException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60572140/
