Spring的jdbcTemplate查询执行原生sql

　　在spring与hibernate整合时进行数据库检索，执行原生sql：

　　

public AppointmentEvaluateVo searchMyfeedbackDetail(String accountId, String fbId) {

        String sql = "select ae.id as fbId ,ae.app_id as appId, a.app_no as appNo,"
                + "    si.service_item AS serItem,a.app_service_time as feedTime,ae.remark as"
                + " feedCon, cou.attitudeScore AS attitudeScore,cou.qualityScore AS qualityScore,"
                + "cou.prescriptionScore AS prescriptionScore from appointment_evaluate ae LEFT JOIN"
                + " appointment a ON ae.app_id=a.id LEFT JOIN organization_service_item     osi  "
                + "ON a.item_id=osi.id LEFT JOIN service_item si ON osi.service_item_id=si.id "
                + "LEFT JOIN  ( SELECT _a.item_id, count(_a.id)    AS orderNum,  _ae.attitude as "
                + "attitudeScore, _ae.quality as qualityScore, _ae.prescription as prescriptionScore  "
                + " FROM appointment _a RIGHT JOIN appointment_evaluate _ae ON `_a`.id = `_ae`.app_id "
                + " GROUP BY _a.item_id) cou ON osi.id = cou.item_id where 1=1 and     ae.creator='" + accountId
                + "'  and ae.id='" + fbId + "';";

        List rows = jdbcTemplate.queryForList(sql);
        AppointmentEvaluateVo av = new AppointmentEvaluateVo();
        Iterator ite = rows.iterator();
        while (ite.hasNext()) {
            Map avMap = (Map) ite.next();
            av.setFbId(avMap.get("fbId").toString());
            av.setAppId(avMap.get("appId").toString());
            av.setAppNo(avMap.get("appNo").toString());
            av.setSerItem(avMap.get("serItem").toString());
            av.setFeedTime(avMap.get("feedTime").toString());
            av.setFeedCon(avMap.get("feedCon").toString());
            av.setTotScore(avMap.get("prescriptionScore").toString());
            av.setTquaScore(avMap.get("qulityScore").toString());
            av.setSerScore(avMap.get("attitudeScore").toString());
        }
        return av;
    }

　　第二种：

　　

public Student findStudentById(int id){
	String sql = "select * from tb_student where id=?";
	final Student student = new Student();
	jdbcTemplate.query(sql,new Object[]{id},new RowCallbackHandler(){
		public void processRow(ReultSet resultSet) throws SQLException{
			student.setId(resultSet.getInt("id"));
			student.setName(resultSet.getString("name"));
		}
	});
	return student;
}
