hibernate - Autowired Service in Validation and Controller cannot save -
i use spring mvc + hibernate + spring security.
my problem cannot save data in database when use checkuserexistvalidator autowired userservice. use autowired userservice in controller to. without checkuserexistvalidator work good.
i think cant use 2 transactional @ same time;
checkuserexistvalidator
public class checkuserexistvalidator implements constraintvalidator<checkuserexist, string>{ @autowired userservice userservice; @override public void initialize(checkuserexist checkuserexist) { } @override public boolean isvalid(string login, constraintvalidatorcontext context) { system.out.println("call valid " + userservice); //when in jsp forms occurs error call //first, when no error call second after //userservice in controller , null if(userservice.findlogin(login) != null){ return false; } return true; } } userserviceimpl
@service("userserviceimpl") public class userserviceimpl implements userservice { @autowired userdao userdao; @override @transactional(readonly = true) public user findlogin(string login) { return this.userdao.findlogin(login); } @override @transactional public void saveuser(user user) { this.userdao.saveuser(user); } } userdaoimpl
@repository("userdao") public class userdaoimpl implements userdao { @autowired private sessionfactory sessionfactory; @suppresswarnings("unchecked") @override public user findlogin(string login) { session session = this.sessionfactory.getcurrentsession(); list<user> user = new arraylist<user>(); user = session .createquery(" user login = :login") .setparameter("login", login).list(); if(user.size() > 0){ return user.get(0); }else{ return null; } } @override public void saveuser(user user) { session session = this.sessionfactory.getcurrentsession(); session.save(user); } } registrationcontroller
@controller public class registrationcontroller { @autowired @qualifier("userserviceimpl") userservice userservice; @modelattribute("user") public user user(){ return new user(); } @requestmapping(value = "/registration", method = requestmethod.get) public string registrationpageget(@modelattribute user user){ return "authorization/registration"; } @requestmapping(value = "/registration", method = requestmethod.post) public string registrationpagepost(@modelattribute @valid user user, bindingresult result){ if(result.haserrors()){ return "authorization/registration"; }else{ system.out.println("call controller " + userservice); userservice.saveuser(user); //when in jsp forms occurs error call //second, when no error call first before //userservice in checkuserexistvalidator } return "redirect:/"; } } and exception
