我出现这个异常提示的原因很奇葩，下面是出错的代码：

    <select id="selectByPrimaryKey" parameterType="studio.geek.entity.StudentInsuranceKey" resultMap="BaseResultMap">        SELECT        <include refid="Base_Column_List"/>        FROM student_insurance        WHENECER student_id = #{studentId,jdbcType=CHAR}        AND insurance_id = #{insuranceId,jdbcType=SMALLINT}    </select>

在红色标注的部分，原本是WHERE，结果写成了WHENEVER。我一直都在查找参数的问题，结果竟然是因为这个。
