spring MVC 代码：

@Controller

@RequestMapping(value= "/district")public classdistrictController {

@ResourceprivateDistrictService districtService;/**

* 获取省列表

* @return

* @throws Exception*/@RequestMapping(value= "getProvinces")

@ResponseBodypublicObject getProvinces() throws Exception {returndistrictService.getProvinces();

}/**

* 获取市列表

* @param province

* @return

* @throws Exception*/@RequestMapping(value= "getCities")

@ResponseBodypublic Object getCities(@RequestParam(value = "province") String province) throws Exception {returndistrictService.getCities();

}//再往下级的获取方式和getCities方法都相同，所以此处略过

}
