Mybatis 报错:There is no getter for property named 'device_no' in 'class
ibatis 报错:There is no getter for property named 'device_no' in 'class.xxx
。
报错位置为 mapper.xml
文件,sql 带入的参数变量找不到:
<update id="updateByDeviceNo" parameterType="CaseGpsInfo">
update case_gps_info
<trim prefix="SET" suffixOverrides=",">
<if test="deviceStatus != null and deviceStatus != ''">device_status = #{deviceStatus},</if>
<if test="deviceStatusMessage != null and deviceStatusMessage != ''">device_status_message = #{deviceStatusMessage},</if>
<if test="supplierName != null and supplierName != ''">supplier_name = #{supplierName},</if>
</trim>
where device_no = #{device_no}
</update>
因为属性名称通常都是驼峰格式,而数据库字段多为下划线。所以这里的 #{device_no}
明显不是 CaseGpsInfo
中的属性,而应该是 deviceNo
。
修改之后问题解决。
