MyBatis map-underscore-to-camel-case not working - mybatis

Question

I am using MyBatis 2.0.0 and have problem: I have a userId and status field that need to retrieve data so I'm using Mybatis for it.
but when I try to get the data the MyBatis don't work and I keep getting the same error.
I've tried to add the lines to application.properties
#mybatis entity scan packages
mybatis.type-aliases-package=com.cnoga.**.dao
#Mapper.xml location
mybatis.mapper-locations=classpath*:/mybatis/**/*.xml
mybatis.configuration.map-underscore-to-camel-case=true
but nothing happend and I still get my error.
I even tried to create the mybatis-config.xml
like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<setting name="mapUnderscoreToCamelCase" value="true" />
</settings>
</configuration>
and add this line to application.properties instead the lines above:
"mybatis.config-location=classpath:/mybatis-config.xml"
The mapper file:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.proj.user.dao.UserMapper" >
<select id="query4Regist" resultType="java.util.Map" parameterType="java.util.Map" >
select u.user_id userId,
status
from t_user u
left join t_user_group ug on u.user_id = ug.user_id
where u.is_del = 1
and u.status between 0 and 4
and (
u.email = #{account,jdbcType=NVARCHAR}
<if test="countryCode != null and countryCode != ''">
or (u.mobile = #{account,jdbcType=NVARCHAR} and u.country_code = #{countryCode,jdbcType=NVARCHAR})
</if>
)
and (u.region_name = #{regionName} or ug.group_id = 7 or ug.group_id = 8)
order by u.user_id desc offset 0 rows fetch next 1 rows only
</select>
</mapper>

I solved the problem!
The problem was using the map functions.
To use MYBATIS I built struct only for the values ​​I wanted to transfer and I just changed in all the places where I called the map functions to get data from the new struct
