Java 回复：我的sql从多个表中获取数据，逗号分隔

吴宇森的以下解决方案：

    "SELECT  d.first_name,
        d.last_name,
        GROUP_CONCAT(s.name) AS `specializations`
    FROM    doctors d
        INNER JOIN doctor_specialization ds
            ON d.id = ds.doctor_id
        INNER JOIN specializations s
            ON ds.specialization_id = s.id
     GROUP   BY d.first_name, d.last_name"

使用GROUP_CONCAT是可行的，但是当使用Spring的JDBC行映射器类将获得的结果集映射到模型类时，这将是无效的

模型类：- 1.java博士

        public class Doctor 
        {
           private int doctorid;
           private String firstname;
           private String middlename;
           private String lastname;
           private String servicesOffered;
           private String profStatement;
           private Date practicingFrom;
           private String consultingDays;
           private String consultingTime;
           private Set doctorSpecializations = new HashSet(0);
           private Set qualifications = new HashSet(0);
           //Getters & Setters;
        }

DoctorSpecialization.java

java

 public class Specialization 
 {
     private int id;
     private String specializationName;
     private Set doctorSpecializations = new HashSet(0);
     //Getters & Setters;
 }

Qualification.java

 public class Specialization 
 {
     private int id;
     private String specializationName;
     private Set doctorSpecializations = new HashSet(0);
     //Getters & Setters;
 }

如何使用Spring的JDBC RowMapper类将获得的结果集映射到模型类中，从而获得上述期望的结果？ 提前谢谢

public class Qualification 
{
    private int id;
    private Doctor doctor;
    private String qualificationName;
    private String instituteName;
    private Date procurementYear;
    //Getters & Setters;
}
