}); 三、后臺(tái)主要代碼 后臺(tái)采用SpringMVC+Spring+Mybatis框架， 以下為Controller層代碼
@ResponseBody
@RequestMapping(value = "/queryAreaInfo", method = { RequestMethod.POST }, produces = MediaType.APPLICATION_JSON_VALUE)
public List queryAreaInfo() {
List areaInfo=new ArrayList<>();
try {
//獲取緩存中的省市區(qū)信息（本項(xiàng)目直接從緩存中獲取，也可以單獨(dú)寫(xiě)方法到Service、Dao層查詢(xún)）
EcncSysConfig sysConfig = new EcncSysConfig();
areaInfo = sysConfig.INIT_SYS_ECNC_AREAVO;
} catch (Throwable e) {
e.printStackTrace();
}
//盛放省份
List result=new ArrayList<>();
for (AreaVO areaVO : areaInfo) {
Map map= new HashMap<>();
if("2".equals(areaVO.getGrade())){
map.put("text", areaVO.getName());
//盛放地市
List cList=new ArrayList<>();
for (AreaVO cVO : areaInfo) {
Map cMap=new HashMap<>();
if (cVO.getParentId() != null && cVO.getParentId().equals(areaVO.getId())) {
cMap.put("text", cVO.getName());
//盛放區(qū)縣
List rList=new ArrayList<>();
for (AreaVO rVO : areaInfo) {
Map rMap=new HashMap<>();
if (cVO.getId().equals(rVO.getParentId())) {
rMap.put("text", rVO.getName());
rList.add(rMap);
}
}
cMap.put("nodes", rList);
cList.add(cMap);
}
}
map.put("nodes", cList);
result.add(map);
}
}
return result;
