R2DBC - IllegalArgumentException：无法编码 java.util.Date 类型的参数

问题描述

我正在使用 R2DBC MysqL 学习 Reative jdbc。我有一个这样的存储库：

public interface VerificationTokenRepository extends ReactiveCrudRepository<VerificationToken,Long> {

VerificationToken 类如下所示：

@Table
public class VerificationToken {

@Id
private final Long id;

@Column
private final String code;

@Column
private final Date validUntil;

@Column
private boolean used;

@Column
private Long userId;

@Column
private Long verificationTokenType;

创建表的脚本是这样的：

create table verification_token (
    id int unsigned not null AUTO_INCREMENT,code varchar(36) not null,valid_until datetime not null,used boolean not null,verification_token_type_id int unsigned not null,user_id int unsigned,PRIMARY KEY (id),constraint verification_token_type_fk FOREIGN KEY (verification_token_type_id) REFERENCES verification_token_type(id),CONSTRAINT user_id_fk FOREIGN KEY (user_id) REFERENCES user(id)
);

当我执行方法 verificationTokenRepository.save 时，控制台显示此错误：

Caused by: java.lang.IllegalArgumentException: Cannot encode parameter of type java.util.Date
    at io.r2dbc.h2.codecs.DefaultCodecs.encode(DefaultCodecs.java:73)

如何使用 R2DBC 存储日期？或者如果 R2DBV 支持它？
