MyBatis 插入后返回值

Question

嘿伙計們，我是 MyBatis 的新手，並試圖從傳入的請求 object 創建一個帳戶，但是當我嘗試這樣做時，它說：

 Mapper method 'com.example.modular.mappers.AccountMapper.createAccount' has an unsupported return type: class com.example.modular.model.Account

映射器：

public interface AccountMapper {

@Select("SELECT * FROM ACCOUNT WHERE id = #{id}")
Account getAccount(@Param("id") Long id);

@Options(useGeneratedKeys=true, keyProperty = "id", keyColumn="id")
@Insert("INSERT INTO ACCOUNT(customerId,country) values (#{customerId},#{country})")
Account createAccount(Account account);

Sql 架構關於架構我不確定我指定的第一行是否正確地寫了 id -> 目標是在插入新記錄時自動遞增 id

 CREATE TABLE IF NOT EXISTS Account
(
    id  INTEGER NOT NULL GENERATED always as identity,
    customerId  INTEGER,
    country  VARCHAR(22)

);

帳戶 model

public class Account {

    @Id
    private Long id;

    @Column("country")
    private String country;

    @Column("customerId")
    private Long customerId;

}

您需要使用以下插入查詢

@Insert("INSERT INTO ACCOUNT(customerId,country) values (#{account.customerId},#{account.country})")
