问题出现背Spring 框架下面 建立如下
Controller --> Service --->Dao --->.xml (ibaties配置文件)
正确格式
1 将SQ语句写入sqlModifyPassword.xml配置文件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://www.ibatis.com/dtd/sql-map-2.dtd"> <sqlMap namespace="ess.modifypassword"> <update id="modifyPassword" parameterClass="linkMap"> <![CDATA[ UPDATE sy_user set PASSWORD = #PASSWORD# where PERSON_ID = #PERSON_ID# and CPNY_ID = #CPNY_ID# ]]> </update> </sqlMap>
将上述文件添加入总配置文件 sqlMapConfig.xml
<sqlMap resource="com/ait/ess/dao/sql/sqlModifyPassword.xml" />
2 DAO实现类 注意@Repository 标志
@Repository public class ModifyPassWordDaoImpl extends SqlMapClientSupport implements ModifyPassWordDao { @Override public boolean modifyPassword(Object obj) { try { this.update("ess.modifypassword.modifyPassword", obj); } catch (SQLException e) { e.printStackTrace(); return false; } return true; } }
DAO 接口 --无特殊之处
public interface ModifyPassWordDao { /** * 修改密码(change password) */ public boolean modifyPassword(Object obj); }
3 Service 实现类 @Service 标志很重要
@Service public class ModifyPassWordSerImpl implements ModifyPassWordSer { Logger logger = Logger.getLogger(ModifyPassWordSerImpl.class); @Autowired private ModifyPassWordDao ModifyPassWordDao; @Override public boolean modifyPassword(HttpServletRequest request) throws Exception { // TODO Auto-generated method stub // 页面提交数据 LinkedHashMap paramMap = getMapByRequest(request); return this.ModifyPassWordDao.modifyPassword (paramMap); /** * 方法说明（中文，英文） * @param parameterObject * @return * @throws Exception */ } /** * 通过request请求封装查询条件(get search conditions for request) * * @param request * @return */ private LinkedHashMap getMapByRequest(HttpServletRequest request) { AdminBean admin = SessionUtil.getLoginUserFromSession(request); // 页面提交数据 LinkedHashMap paramMap = ObjectBindUtil.getRequestParamData(request); paramMap.put("PERSON_ID", admin.getPersonId()); paramMap.put("CPNY_ID", admin.getCpnyId()); paramMap.put("PASSWORD", admin.getPassword ()); return paramMap; } }
Service 接口 -- 无特殊之处
public interface ModifyPassWordSer { public boolean modifyPassword(HttpServletRequest request) throws Exception; }
Ctroller
@Controller @RequestMapping(value = "/ess/modify") public class ModifyPassWordCtroller { Logger logger = Logger.getLogger(ModifyPassWordCtroller.class); @Autowired private ModifyPassWordSer modifyPassWordSer; /** * 密码修改(change password) * * @param request * @param response * @param modelMap * @return * @throws Exception */ @SuppressWarnings("unchecked") @RequestMapping(value = "/ModifyPassword") public Map<String, Object> viewPersonInfoApplyConfirmList( HttpServletRequest request, HttpServletResponse response, ModelMap modelMap) throws Exception { Map<String, Object> map = new HashMap<String, Object>(); boolean result; try { result = modifyPassWordSer.modifyPassword(request); if (result) { map.put("navTabId", "ess0301"); map.put("message", TipMessage.getTipMessage("alert.message.hr.modifypassword.modifypassword_success",request));//个人密码修改成功 map.put("statusCode", "200"); // map.put("callbackType", "closeCurrent"); } else { map.put("message", TipMessage.getTipMessage("alert.message.hr.modifypassword.modifypassword_fail",request));//个人密码修改失败,请重试！ map.put("statusCode", "300"); } } catch (Exception e) { e.printStackTrace(); } return map; } }
