     <option></option>
     <option value="RE_GOODS_CODE">货物编号</option>
     <option value="RE_OLD_CODE">流水号</option>

} 
机构码
select gr_name,gr_hcode from T_GROUP t order by gr_hcode
机构名称，层次码
//将查询结果给jq中的grid
public String select(){
  ScanLessQuery sg = new ScanLessQuery();
  sg = queryParameter();
        jsonObject = scanLessQueryService.select(sg);
  return "jsonObject";
 }
 //通过jq给属性赋值，把属性值赋给实体类
 private ScanLessQuery queryParameter() {
  ScanLessQuery sg = new ScanLessQuery();
  // 当前页
  intPage = Integer.parseInt((page == null || page == "0") ? "1" : page);
  // 每页显示条数
  number = Integer.parseInt((rows == null || rows == "0") ? "25" : rows);
  // 每页的开始记录 第一页为1 第二页为number +1
  start = (intPage - 1) * number;
  sg.setPage_start(start);
  sg.setPage_end(start + number);
  // 页面查询时间类型判断
  sg.setSl_start_time(sl_start_time);
  sg.setSl_end_time(sl_end_time);
  sg.setGrSendName(grSendName);
  sg.setGrSendCode(grSendCode);
  sg.setGhSendCode(ghSendCode);
  sg.setGrArriveCode(grArriveCode);
  sg.setGrArriveName(grArriveName);
  sg.setGhArriveCode(ghArriveCode);
        sg.setSi_type(si_type);
        sg.setSelect_term(select_term);
  sg.setText_term(text_term);
  return sg;
 }
service中，拼装jsonObject，格式。
 public JSONObject select(ScanLessQuery scanLessQuery) {
  List<ScanLessQuery> result = scanLessQueryDao.select(scanLessQuery);
  int count = scanLessQueryDao.selectCount(scanLessQuery);
  Map<String, Object> jsonMap = new HashMap<String, Object>();
  jsonMap.put("total", count);
  jsonMap.put("rows", result);
  return JSONObject.fromObject(jsonMap);
 }
  dao中通过mybatis将xml和dao关联起来
  public interface ScanLessQueryDao {
 
 /**
  * 查询数据
  * @param scanLessQuery
  * @return
  */
 public List<ScanLessQuery> select(ScanLessQuery scanLessQuery);
 
 /**
  * 查询数据条数
  * @param scanLessQuery
  * @return
  */
 public int selectCount(ScanLessQuery scanLessQuery);
 /**
  * 导出数据
  * @param scanLessQuery
  * @return
  */
 public List<ScanLessQuery> selectForExcel(ScanLessQuery scanLessQuery);
 
}
注意名称是xml中的名称
<mapper namespace="com.strong.cjtransit.dao.scan.ScanLessQueryDao">
 <!-- 查询数据 -->
 <select id="select" resultType="ScanLessQuery" parameterType="ScanLessQuery">

 注意daoxml中的oracle 分页查询
  ***需要修改的配置文件***
  在web-info下的class中
  1.mybatis-config.xml
  配置类的别名，注意新建实体类一定要修改此文件
  配置映射，配置daoxml的位置
  2.struts-config配置
   
  <!-- 扫描少货信息查询 -->
  <action name="scanLessQuery" class="scanLessQueryAction">
   <result name="main">/WEB-INF/jsp/scan/scan_less_query.jsp</result>
   <result name="jsonObject" type="json">
     <param name="root">jsonObject</param>
   </result>
   <result name="excel" type="stream"> 
           <param name="contentType">application/vnd.ms-excel</param> 
           <param name="contentDisposition">attachment;filename="${downloadFileName}"</param> 
           <param name="bufferSize">1024</param>
           <param name="inputName">excelFile</param> 
             </result>
   <interceptor-ref name="mydefault" />
  </action>
  配置action 配置result等
  注意class中对应地址在spring中相对应
 3.spring-config起到胶水的作用
 例如：
 <!-- 货物扫描信息查询dao -->
 <bean id="scanGoodsQueryDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
  <property name="mapperInterface" value="com.strong.cjtransit.dao.scan.ScanGoodsQueryDao"/>

  <!-- 货物扫描信息查询service -->

 </bean>
  <!-- 货物扫描信息查询Action -->
