使用 UUIDTypeHandler 時 UUID 插入失敗

[英]UUID insert fails when using a UUIDTypeHandler

 原文  2022-08-05 00:36:01  9   1    mybatis/ spring-mybatis/ mybatis-mapper

問題描述

我正在嘗試將 UUID 值插入到 Postgresql 表中，因此我定義並配置了一個 UUIDTypeHandler 以在 mybatis 級別處理此問題。

不幸的是，插入操作失敗並出現以下錯誤。

類型處理程序定義如下所示： http://www.java2s.com/example/java-src/pkg/debop4k/data/mybatis/typehandlers/postgres/uuidtypehandler-cb65d.html

我的 xml 映射器如下所示。 userId 字段保存 UUID 值：

<insert id="createUser" parameterType="com.kp.mw.db.dbos.UserDBO">
        INSERT INTO users (id, username, email, birth_year, birth_month, password, creation_time, verification_token, country, language)
        VALUES (#{userId}, #{user.username}, #{user.email}, #{user.birthYear}, #{user.birthMonth}, #{user.password}, #{user.creationTime}, #{user.verificationToken}, #{user.country}, #{user.language})
    </insert>

知道如何解決這個問題嗎？ 謝謝

我設法通過從 setObject 調用中刪除 jdbcType.TYPE_CODE 參數來解決我的問題。

@Override
    public void setNonNullParameter(PreparedStatement ps, int i, UUID parameter, JdbcType jdbcType)
            throws SQLException {
        ps.setObject(i, parameter);
    }
