public class TeaExp extends PmsUserTea{
    private List pmsExps;

    public List getPmsExps() {
        return pmsExps;
    }

    public void setPmsExps(List pmsExps) {
        this.pmsExps = pmsExps;
    }
}

编写PmsUserTeaMapper.xml文件

resultMap定义

sql语句定义

    SELECT DISTINCT
pms_user_tea.id AS teaId,
pms_user_tea.nickname,
pms_exp.exp_name AS expName,
pms_exp.id AS expId
FROM
    pms_user_tea ,pms_exp
WHERE pms_user_tea.id=pms_exp.tutor_id

  

编写服务测试
