前言：
.updateById(DAO对象);Mybatis处理会把整个对象都给update掉，添加注解：@TableField(value = "news", strategy = FieldStrategy.IGNORED) 会全部的进行update哪怕是null 也会更新！
问题描述：
解决办法：
/**
* 数据源转化率(新源没有转化率的按照3算)模型2舆情
*/
@TableField(value = "convert_score_yq", strategy = FieldStrategy.IGNORED)
private Double convertScoreYq;
/**
* 模型1得分
*/
@TableField(value = "model_total_score_news", strategy = FieldStrategy.IGNORED)
private Double modelTotalScoreNews;
/**
* 模型2得分
*/
@TableField(value = "model_total_score_yq", strategy = FieldStrategy.IGNORED)
private Double modelTotalScoreYq;运行的SQL：
==> Preparing: UPDATE tbm_factor_score SET source_type_score_news=?, subject_type_score_news=?, subject_type_score_yq=?, range_type_score_news=?, title_importance_score_news=?, title_importance_score_yq=?, title_negative_score_news=?, title_negative_score_yq=?, media_column_score_news=?, media_column_score_yq=?, media_source_score_news=?, sentiment_score_news=?, sentiment_score_yq=?, convert_score_news=?, convert_score_yq=?, model_total_score_news=?, model_total_score_yq=?, update_user_id=?, create_time=?, update_time=? WHERE id=?
