返回Map,Mybatis配置如下 ：

 select name,id from tsql_test_region where id=#{id} 

ServiceImpl如下 ：

public Map
    
      getCountyHashMap(long id) {    Map
     
       regionMap = regionInfoMapper.getCountyHashMap(id); Map
      
        resultMap = new HashMap
       
        (); String region = null; Long vid = null; for (Map.Entry
        
          entry : regionMap.entrySet()) { if ("NAME".equals(entry.getKey())) { region = (String) entry.getValue(); } else if ("ID".equals(entry.getKey())) { vid = ((java.math.BigDecimal) entry.getValue()).longValue(); } } resultMap.put(region, vid); return resultMap; }
        
       
      
     
    

Controller如下 :

@RequestMapping(value = "/region3", method = RequestMethod.GET)  public @ResponseBody Map
    
      getCountyMap(@RequestParam(required = true) int regionId) { return regionInfoService.getCountyHashMap(regionId); }
    

结果为 ：

     返回List<Map>类似 :

Mybatis配置 :

 select name,id from tsql_test_region order by id 

ServiceImpl如下 :

public Map
    
      getRegionHashMap() {    List
     
    

Controller如下 :

@RequestMapping(value = "/region2", method = RequestMethod.GET)  public @ResponseBody Map
    
      getRegionMap() { return regionInfoService.getRegionHashMap(); }
    

结果为 ：
