从K-V表中查出数据将数据以下拉框的形式展示出来

结果展示：

JSP中：

js中：

$.ajax({
   type : 'POST',
   url : ctx + "/planDef/redirictUrl.do",
   success : function(data) {
       mini.getbyName("redirict_url").setData(mini.encode(data));
   }
});

controller中：

@RequestMapping("/{key}.do")
   @ResponseBody
   public Object queryKVInfo(HttpServletRequest request, HttpServletResponse response, @PathVariable("key") String key)
           throws Exception {
       logger.info("DefKVController.queryKVInfo.into...");
       logger.info("请求数据:[{}]", key);
       if (StringUtils.isBlank(key)) {
           throw new BusinessException("key值为空");
       }
       List<DefKVInfoResDto> result = keyValueService.queryKVInfo(key);

       logger.info("DefKVController.queryKVInfo.out...");
       return result;
   }
service中：

public List<DefKVInfoResDto> queryKVInfo(String key);

serviceImpl中：

@Override
   public List<DefKVInfoResDto> queryKVInfo(String key) {
       DefKvExample defKvExample = new DefKvExample();
       defKvExample.createCriteria().andKEqualTo(key);
       List<DefKv> list = defKvMapper.selectByExample(defKvExample);

       if (list.size() == 0 || list == null) {
           throw new BusinessException("未查询到有效的value值");
       }

       List<DefKVInfoResDto> kvList = new ArrayList<DefKVInfoResDto>();
       for (DefKv defKv : list) {
           DefKVInfoResDto resDto = new DefKVInfoResDto();
           resDto.setKey(defKv.getK());
           resDto.setValue(defKv.getV());
           resDto.setRemark(defKv.getR());
           kvList.add(resDto);
       }

return kvList;
}

DefKVInfoResDto 中：

public class DefKVInfoResDto {

   private String key;
   private String value;
   private String remark;

   public String getKey() {
       return key;
   }

   public void setKey(String key) {
       this.key = key;
   }

   public String getValue() {
       return value;
   }

   public void setValue(String value) {
       this.value = value;
   }

   public String getRemark() {
       return remark;
   }

   public void setRemark(String remark) {
       this.remark = remark;
   }

mapper中：

List<DefKv> selectByExample(DefKvExample example);

mapper.xml中：
