When the problem occurs, the following is set up under the Spring framework:

Controller --> service ---> Dao --->. XML (ibaties configuration file)

Correct format

1. Write the SQ statement to the sqlmodifypassword. xml configuration file.

 <?  XML version = "1.0" encoding = "UTF-8"  ?>  <! Doctype sqlmap public "-// ibatis.com//dtd SQL map 2.0 //" 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  > 

Add the preceding file to the configuration file sqlmapconfig. xml.

 
<SqlmapResource= "Com/AIT/ESS/Dao/SQL/sqlmodifypassword. xml" />
 

 

2 DAO implementation class notes@ RepositoryFlag

@ 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 interface -- no special features

Public InterfaceModifypassworddao {/*** Change Password)*/Public BooleanModifypassword (Object OBJ );}
 

 

3 service implementation class@ Service flag is very important

 

 @ Service  Public   Class Modifypasswordserimpl Implements Modifypasswordser {logger Logger = Logger. getlogger (modifypasswordserimpl. Class  );@ Autowired  Private  Modifypassworddao; @ override  Public   Boolean Modifypassword (httpservletrequest request) Throws  Exception {  //  Todo auto-generated method stub  // Submit data on the page Linkedhashmap parammap = Getmapbyrequest (request );  Return   This  . Modifypassworddao. modifypassword (parammap );  /**  * Method description (Chinese and English )*  @ Param  Parameterobject *  @ Return  *  @ Throws  Exception  */ }  /**  * Get search conditions for request encapsulation )**  @ Param  Request *  @ Return       */      Private  Linkedhashmap getmapbyrequest (httpservletrequest request) {adminbean Admin = Sessionutil. getloginuserfromsession (request );  //  Submit data on the page 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 Interface -- no special features

Public InterfaceModifypasswordser {Public BooleanModifypassword (httpservletrequest request)ThrowsException ;}
