When I insert a date in Jooq, I get this error: column creation_date is of type timestamp with time zone but expression is of type character varying

Question

我正在使用 Spring boot 和 postgresql，这是我的“pom.xml”文件：

我想像这样插入一个用户对象：

User:
  userId --> Long
  name --> String
  password --> String
  creationDate --> ZonedDateTime
  modifitionDate --> ZonedDateTime

在数据库中：

Users:
  user_id --> bigint
  name --> character varying
  password --> character varying
  creation_date --> timestamp with time zone
  modifition_date --> timestamp with time zone

但是当我尝试插入用户时：

@Autowired
DSLContext ctx;
...
Users users=Users.USERS;
ctx.insertInto(users, Arrays.asList(users.NAME, users.PASSWORD, users.CREATION_DATE, users.MODIFICATION_DATE))
   .values(Arrays.asList("user1","password",ZonedDateTime.now(),ZonedDateTime.now()))
   .execute();

我收到这个错误：

column 'creation_date' is of type timestamp with time zone but expression is of type character varying

我意识到 jooq 创建的用户 class 的“creation_date”字段为“TableField”类型而不是“TableField”

public final TableField<UsersRecord, OffsetDateTime> CREATION_DATE= createField(DSL.name("creation_date"), SQLDataType.TIMESTAMPWITHTIMEZONE(6).nullable(false), this, "");

我尝试将 creation_date 字段从 ZonedDateTime 转换为 OffsetDateTime，然后将其放入“值”方法中，但它也不起作用，我得到了同样的错误

如何正确注册用户？

我认为您需要将此参数添加到连接字符串中：stringtype=unspecified

例如： jdbc:postgresql://127.0.0.1:5432/testdb?stringtype=unspecified
