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

1. <?xml version="1.0" encoding="UTF-8"?>
2. <!DOCTYPE sqlMap
3.     PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"
4.     "http://www.ibatis.com/dtd/sql-map-2.dtd">
5. <sqlMap namespace="ess.modifypassword">
6. <update id="modifyPassword" parameterClass="linkMap">
7.     <![CDATA[
8.               UPDATE sy_user set PASSWORD =  #PASSWORD#  where PERSON_ID =  #PERSON_ID# and CPNY_ID = #CPNY_ID#
9.     ]]>
10. </update>
11. </sqlMap>

复制代码

将上述文件添加入总配置文件 sqlMapConfig.xml

1. <sqlMap resource="com/ait/ess/dao/sql/sqlModifyPassword.xml" />

复制代码

2 DAO实现类 注意@Repository 标志

1. @Repository
2. public class ModifyPassWordDaoImpl extends SqlMapClientSupport  implements ModifyPassWordDao {
4.     @Override
5.     public boolean modifyPassword(Object obj) {
6.         try {
7.             this.update("ess.modifypassword.modifyPassword", obj);
8.          
9.         } catch (SQLException e) {
10.             e.printStackTrace();
11.             return false;
12.         }
13.         return true;
16.     }
19. }

复制代码

DAO 接口 --无特殊之处

1. public interface ModifyPassWordDao {
2.     /**
3.      * 修改密码(change password)
4.    
5.      */
6.     public boolean modifyPassword(Object obj);
7. }

复制代码

3 Service 实现类 @Service 标志很重要

1. [b]@Service
2. [/b]public class ModifyPassWordSerImpl implements ModifyPassWordSer {
3.     Logger logger = Logger.getLogger(ModifyPassWordSerImpl.class);
5.    [b] @Autowired
6. [/b]private ModifyPassWordDao ModifyPassWordDao;
7.    
8.    
9.     @Override
10.     public boolean modifyPassword(HttpServletRequest request) throws Exception {
11.         // TODO Auto-generated method stub
12.         // 页面提交数据
13.                 LinkedHashMap paramMap = getMapByRequest(request);
14.                 return this.ModifyPassWordDao.modifyPassword (paramMap);
15.         /**
16.          * 方法说明（中文，英文）
17.          * @param parameterObject
18.          * @return
19.          * @throws Exception
20.          */
22.     }
23.     /**
24.      * 通过request请求封装查询条件(get search conditions for request)
25.      *
26.      * @param request
27.      * @return
28.      */
29.     private LinkedHashMap getMapByRequest(HttpServletRequest request) {
30.         AdminBean admin = SessionUtil.getLoginUserFromSession(request);
31.         // 页面提交数据
32.         LinkedHashMap paramMap = ObjectBindUtil.getRequestParamData(request);
33.         paramMap.put("PERSON_ID", admin.getPersonId());
34.         paramMap.put("CPNY_ID", admin.getCpnyId());
35.         paramMap.put("PASSWORD", admin.getPassword ());
36.         return paramMap;
37.     }
38. }

复制代码

Service 接口 -- 无特殊之处

1. public interface ModifyPassWordSer {
2.     public boolean modifyPassword(HttpServletRequest request)
3.             throws Exception;
4. }

复制代码

Ctroller

1. [b]@Controller
2. @RequestMapping(value [/b][b]= "/ess/modify")
4. [/b]public class ModifyPassWordCtroller {
5.     Logger logger = Logger.getLogger(ModifyPassWordCtroller.class);
6.    
7.    
8.   [b] @Autowired
9. [/b]private ModifyPassWordSer modifyPassWordSer;
10.     /**
11.      * 密码修改(change password)
12.      *
13.      * @param request
14.      * @param response
15.      * @param modelMap
16.      * @return
17.      * @throws Exception
18.      */[b]
19. @SuppressWarnings("unchecked"[/b][b])[/b]
20.     @RequestMapping(value = "/ModifyPassword")
21.     public Map<String, Object> viewPersonInfoApplyConfirmList(
22.             HttpServletRequest request, HttpServletResponse response,
23.             ModelMap modelMap) throws Exception {
24.         
25.         Map<String, Object> map = new HashMap<String, Object>();
26.         boolean result;
27.         try {
28.             result = modifyPassWordSer.modifyPassword(request);
29.             if (result) {
30.                 map.put("navTabId", "ess0301");
31.                 map.put("message", TipMessage.getTipMessage("alert.message.hr.modifypassword.modifypassword_success",request));//个人密码修改成功
32.                 map.put("statusCode", "200");
33.                 // map.put("callbackType", "closeCurrent");
34.             } else {
35.                 map.put("message", TipMessage.getTipMessage("alert.message.hr.modifypassword.modifypassword_fail",request));//个人密码修改失败,请重试！
36.                 map.put("statusCode", "300");
37.             }
38.         } catch (Exception e) {
39.             e.printStackTrace();
40.         }
41.         return map;
42.       
43.     }
44. }
