春季数据无法在 PostgreSQL 数组中保存 PostgreSQL 类型的实体

问题描述

Postgresql 中有如下 DTO：

create table email
(
    account_id varchar(100),id varchar(100),recipients recipient[],subject varchar(100),content varchar(100)
);
create type recipient as
(
    email text,name  text
);

使用库 com.vladmihalcea:hibernate-types-52 获取额外类型。
使用 Spring Data JPA。

有一个用于自定义类型的 Java 类：

@Data
@AllArgsConstructor
public class Recipient {
  @Column(name = "email",columnDeFinition = "TEXT")
  private String email;

  @Column(name = "name",columnDeFinition = "TEXT")
  private String name;
}

实体有一个 Java 类：

@Table(name = "email")
@TypeDef(
    name = "list-array",typeClass = ListArrayType.class
)
public class Email {
    @Column(name = "account_id",columnDeFinition = "TEXT")
    private String accountId;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id",columnDeFinition = "TEXT")
    private String id;

    @Type(
        type = "com.vladmihalcea.hibernate.type.array.ListArrayType",parameters = {
            @Parameter(
                name = ListArrayType.sql_ARRAY_TYPE,value = "recipient"
            )
        }
    )
    @Column(
        name = "recipients",columnDeFinition = "recipient[]"
    )
    private List<Recipient> recipients;

    @Column(name = "subject",columnDeFinition = "TEXT")
    private String subject;

    @Column(name = "content",columnDeFinition = "TEXT")
    private String content;
}

但是，当我尝试保存实体时，出现错误：

Could not execute statement; sql [n/a]; nested exception is org.hibernate.exception.DataException: Could not execute statement
Caused by: org.postgresql.util.PsqlException: ERROR: malformed record literal: "Recipient(email=some email,name=some name)"
  Detail: Missing left parenthesis.

请帮忙解决这个问题。
