对比老师代码的运行结果多了个逗号，明明ProductMapper.xml都一样，为什么会这样？？
老师的

我的

一样的xml

update mmall_product


category_id = #{categoryId,jdbcType=INTEGER},


name = #{name,jdbcType=VARCHAR},


subtitle = #{subtitle,jdbcType=VARCHAR},


main_image = #{mainImage,jdbcType=VARCHAR},


sub_images = #{subImages,jdbcType=VARCHAR},


detail = #{detail,jdbcType=VARCHAR},


price = #{price,jdbcType=DECIMAL},


stock = #{stock,jdbcType=INTEGER},


status = #{status,jdbcType=INTEGER},


create_time = now(),


update_time = now(),老师这边有逗号，我有没有都报错


where id = #{id,jdbcType=INTEGER}

Error updating database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘where id = 28’ at line 33

The error may involve com.mmall.dao.ProductMapper.updateByPrimaryKeySelective-Inline

The error occurred while setting parameters

SQL: update mmall_product SET category_id = ?, name = ?, subtitle = ?, main_image = ?, sub_images = ?, detail = ?, price = ?, stock = ?, status = ?, create_time = ?, update_time = now(), where id = ?
