第一种方案：默认数组角标：
service
Public User selectUser(String name,String area);
mapper：
<
select
id=
"selectUser"
resultMap=
"BaseResultMap"
>
select
*
from
user_user_t
where
user_name = #{0}
and
user_area=#{1}
</
select
>
第二种方案：map集合传参：
service：
Map paramMap=new hashMap();
paramMap.put(“userName”,”对应具体的参数值”);
paramMap.put(“userArea”,”对应具体的参数值”);
Public
User
selectUser(Map paramMap);
mapper：
<
select
id=
" selectUser"
resultMap=
"BaseResultMap"
>
select
*
from
user_user_t
where
user_name = #{userName，jdbcType=
VARCHAR
}
and
user_area=#{userArea,jdbcType=
VARCHAR
}
</
select
>
第三种方案：参数修正
service
Public
User
selectUser(@param(“userName”)Stringname,@param(“userArea”)String area);
mapper：
<
select
id=
" selectUser"
resultMap=
"BaseResultMap"
>
select
*
from
user_user_t
where
user_name = #{userName，jdbcType=
VARCHAR
}
and
user_area=#{userArea,jdbcType=
VARCHAR
}
</
select
>
