mybatis 参数判断报错的问题
<!-- 是否品牌客户 品牌字段不为空 -->
<if test="brandCustomer != null">
<if test="brandCustomer == '是'">
and (c.brand is not null and c.brand !='')
</if>
<if test="brandCustomer == '否'">
and (c.brand is null or c.brand ='')
</if>
</if>
执行报错
<!-- 是否品牌客户 品牌字段不为空 -->
<if test="brandCustomer != null">
<if test="brandCustomer == '是'.toString()">
and (c.brand is not null and c.brand !='')
</if>
<if test="brandCustomer == '否'.toString()">
and (c.brand is null or c.brand ='')
</if>
</if>
因为'' 会转为char
