后台action代码
public class StationAction extends BaseAction { private List<Map<String, Object>> provinceList; public void setProvinceList(List<Map<String, Object>> provinceList) { this.provinceList = provinceList; } public List<Map<String, Object>> getProvinceList() { return provinceList; } public String getProvinceJSON(){ String sql="SELECT PK_ID PROVINCEID,NAME PROVINCENAME FROM T_DICT_DISTRICT A WHERE A.DISTRICT_LEVEL=20"; provinceList= stationService.findBySQL(sql); return "json_getProvinceList"; } }strtus xml配置
<result name="json_getProvinceList" type="json" > <param name="root">provinceList</param> </result>
