mybatis sql日志：

注意： “萧亚轩”两边没有单引号，不是“？”的占位符，参数列表里面是没有值。

修改其实很简单：

v1：换$ 为#

<select id="xxxx" resultType="hashmap">
    select * from talbe_a a where  a.kpeople = #{name}
</select>

v2：添加 ‘’ 单引号

<select id="xxxx" resultType="hashmap">
    select * from talbe_a a where  a.kpeople = ‘${name}‘
</select>

#只会当成个字符串

$就不一定是字符串，或者其他类型
