Spring 数据 JDBC SQLFeatureNotSupportedException 将枚举列表保存到 MySql
Spring Data JDBC SQLFeatureNotSupportedException while saving list of enum to MySql
我有一个名为 Role 的模型。 role 有一个 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
您也可以签出 https://github.com/tirbison/spring-data-jdbc-kotlin/tree/bug/mysql-list-of-enum 来重现错误，不要忘记更改 mysql 凭据。
Role.kt
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
}
架构
create table role
(
id serial primary key,
name varchar(256),
permissions varchar(256)
);
我没有单独的 table 权限，因为 我找不到将 enum 集合保存到 table 的方法spring-data-jdbc，可以是单独的table，也可以是不太重要的列。
当我使用 H2 内存数据库时，我没有得到任何异常，H2 以逗号分隔的形式将枚举保存到列中。但是，当我使用 MySql 时，我得到以下异常堆栈跟踪：

Spring 数据 JDBC 目前支持持久列表的两种变体。
当内容是实体时，它会存储在单独的 table 中。
当内容是简单类型时，如果数据库支持，它会存储在数组中。
由于 MySql 不支持数组，您只能使用第一个变体。
但是枚举是简单类型（即它们可以直接存储在列中）。
解决方案是将枚举包装在实体类型中，即具有包含枚举的单个属性的简单类型。
另一种解决方案是制作 permissions @Transient 并将私有字段持久保存到 DB
import org.springframework.data.annotation.Id
import org.springframework.data.annotation.Transient
class Role(
val name: String
) {
@Id
var id: Long? = null
@Transient
var permissions: List<Permission> = emptyList()
get() {
return permissionList.split(",").map { Permission.valueOf(it.trim()) }
}
set(value) {
field = value
permissionList = value.joinToString()
}
private var permissionList: String = ""
}
和数据库模式
create table role
(
id serial primary key,
name varchar(256),
permission_list varchar(256)
);
spring 数据 jdbc 不会像 @Transient 那样尝试保留 permissions 但会保留 permissionList.
permission_list saved as a csv

Spring 数据 JDBC 目前支持持久列表的两种变体。
当内容是实体时，它会存储在单独的 table 中。
当内容是简单类型时，如果数据库支持，它会存储在数组中。
由于 MySql 不支持数组，您只能使用第一个变体。 但是枚举是简单类型（即它们可以直接存储在列中）。
解决方案是将枚举包装在实体类型中，即具有包含枚举的单个属性的简单类型。
另一种解决方案是制作 permissions @Transient 并将私有字段持久保存到 DB
import org.springframework.data.annotation.Id
import org.springframework.data.annotation.Transient
class Role(
val name: String
) {
@Id
var id: Long? = null
@Transient
var permissions: List<Permission> = emptyList()
get() {
return permissionList.split(",").map { Permission.valueOf(it.trim()) }
}
set(value) {
field = value
permissionList = value.joinToString()
}
private var permissionList: String = ""
}
和数据库模式
create table role
(
id serial primary key,
name varchar(256),
permission_list varchar(256)
);
spring 数据 jdbc 不会像 @Transient 那样尝试保留 permissions 但会保留 permissionList.
permission_list saved as a csv
