ResultMap由于重复映射产生的全小写property，高版本映射到PO类失败

问题复现

<resultMap id="BaseResultMap" type="com.xxx.Student">
    <id column="student_id", jdbcType="BIGINT" property="studentId">
    <result column="student_name", jdbcType="VARCHAR" property="studentName">
</resultMap>

<select id="query" resultMap="BaseResultMap">
    select 
    student_id as studentId,
    student_name as studentName
    from student where deleted = 0
</select>

@Data
public class Student {
    private Long studentId;
    private String studentName;
}

pom版本

老项目
mybatis: 3.4.1

查询出的column：studentid、studentname，查询正常映射到Student

新项目
mybatis: 3.5.7

查询出的column：studentid、studentname，查询映射到Student，属性均为空

问题代码定位:
高版本jar包

低版本无问题jar包

Thanks for the demo, @sayhi-captain .

The class User has two properties userId and userName.
And these properties are explicitly mapped in the result map, so auto-mapping is not applied to these properties.
This is the right behavior.
