hibernate实现多表联合查询

Session session = getHibernateTemplate().getSessionFactory()
   .getCurrentSession();
   StringBuffer sb = new StringBuffer(" select user.username,user.truename,user.sex,user.idnum,user.level,s.sumScore fromScore as s,Examuser as user where s.id.userId = user.id ");
   if(score != null){
    if(score.getExamId()!=null && !"".equals(score.getExamId())
      && !"null".equals(score.getExamId())){
     sb.append(" and s.examId =:examId ");
    }
    if(score.getExamPlace()!=null && !"".equals(score.getExamPlace())
      && !"null".equals(score.getExamPlace())){
     sb.append(" and s.examPlace =:examPlace ");
    }
    if(score.getUsername()!=null && !"".equals(score.getUsername())
      && !"null".equals(score.getUsername())){
     sb.append(" and s.username like:username ");
    }
   }
   sb.append(" order by s.sumScore desc ");
   Query q = session.createQuery(sb.toString());
   if(score != null){
    if(score.getExamId()!=null && !"".equals(score.getExamId())
      && !"null".equals(score.getExamId())){
     q.setParameter("examId",score.getExamId());
    }
    if(score.getExamPlace()!=null && !"".equals(score.getExamPlace())
      && !"null".equals(score.getExamPlace())){
     q.setParameter("examPlace",score.getExamPlace());
    }
    if(score.getUsername()!=null && !"".equals(score.getUsername())
      && !"null".equals(score.getUsername())){
     q.setParameter("username","%"+score.getUsername()+"%");
    }
   }
   List list = q.list();

需要将查询的结果集 进行一下转换：

List stuList = scoreService.findAllScore(queryScore, null); // 返回的结果集
   if(stuList != null && stuList.size()>0){
    list = new LinkedList();
    StudentScore st;
    for(int i = 0; i < stuList.size();i++){
     st = new StudentScore();
     Object[] object = (Object[])stuList.get(i);// 每行记录不在是一个对象 而是一个数组
     String userId =  (String)object[0];
     String username =  (String)object[1];
     String truename =  (String)object[2];
     String sex =  (String)object[3];
     String idnum =  (String)object[4];
     String level =  (String)object[5];
     Double sumScore =  Double.parseDouble(String.valueOf(object[6]));
     String paperId =  (String)object[7];
     // 重新封装在一个javabean里面
     st.setUserId(userId);
     st.setUsername(username);
     st.setTruename(truename);
     st.setIdnum(idnum);
     st.setLevel(DictSwitch.getValue("DICT_LEVEL",level));
     st.setSex(DictSwitch.getValue("DICT_SEX",sex));
     st.setPaperId(paperId);
     st.setSumScore(sumScore);
     st.setExamplace(DictSwitch.getValue("DICT_EXAMSTATION",examplace));
     list.add(st); // 最终封装在list中 传到前台。
    }
