1. Introducing the relevant JAR package

2. Configure the spring configuration file named Applicationcontext.xml(configured and placed in the src directory)

4. Example Daoimpl

Package Com.java1234.dao.impl;

Import java.util.List;

Import Javax.annotation.Resource;

Import Org.hibernate.Query;
Import org.hibernate.Session;
Import Org.hibernate.SessionFactory;
Import org.springframework.beans.factory.annotation.Autowired;
Import Org.springframework.stereotype.Repository;

Import Com.java1234.dao.UserDao;
Import Com.java1234.model.User;

@Repository
public class Userdaoimpl implements userdao{

Private Sessionfactory sessionfactory;

@Override
Public user login (user user) throws Exception {
User Resultuser=null;
Session session=this.getsession ();
Query query=session.createquery ("from User u where u.username=?") and u.password=? ");
Query.setstring (0, User.getusername ());
Query.setstring (1, User.getpassword ());
@SuppressWarnings ("Unchecked")
List<user> userlist= (list<user>) query.list ();
if (Userlist.size () >0) {

}

@Resource
@Autowired
public void Setsessionfactory (Sessionfactory sessionfactory) {
This.sessionfactory = sessionfactory;
}

Public Session getsession () {
return Sessionfactory.getcurrentsession ();
}

}

5. Example Serviceimpl

Package Com.java1234.service.impl;

Import Javax.annotation.Resource;

Import Org.springframework.stereotype.Service;

Import Com.java1234.dao.UserDao;
Import Com.java1234.model.User;
Import Com.java1234.service.UserService;

@Service
public class Userserviceimpl implements userservice{

@Resource
Private Userdao Userdao;

@Override
Public user login (user user) throws Exception {
return Userdao.login (user);
}

}

6. Example action

Package com.java1234.action;

Import Javax.annotation.Resource;
Import Javax.servlet.http.HttpServletRequest;
Import javax.servlet.http.HttpSession;

Import org.apache.struts2.convention.annotation.Action;

Import Com.java1234.model.User;
Import Com.java1234.service.UserService;
Import Com.java1234.util.StringUtil;
Import Com.opensymphony.xwork2.ActionSupport;

@Scope ("prototype")
@Namespace ("/")
@Action (value= "Login", results={@Result (name= "Success", type= "redirect", location= "/main.jsp"), @Result (name= " Error ", location="/index.jsp ")})
public class Loginaction extends Actionsupport implements servletrequestaware{

/**
*
*/
Private static final long serialversionuid = 1L;

@Resource
Private UserService UserService;

private user user;
Private String error;
Private String Imagecode;

Public User GetUser () {
return user;
}

public void SetUser (user user) {

}

Public String GetError () {
return error;
}

public void SetError (String error) {
This.error = error;
}

Public String Getimagecode () {
return imagecode;
}

public void Setimagecode (String imagecode) {
This.imagecode = Imagecode;
}

HttpServletRequest request;

@Override
Public String Execute () throws Exception {
Get session
HttpSession session=request.getsession ();
if (Stringutil.isempty (User.getusername ()) | | Stringutil.isempty (User.getpassword ())) {
error= "User name or password is empty! ";
return ERROR;
}

Error= "Verification code is empty! ";
return ERROR;

return ERROR;
}
try {

if (currentuser==null) {
error= "User name or password is wrong! ";
return ERROR;
}else{
Session.setattribute ("CurrentUser", CurrentUser);
return SUCCESS;
}
} catch (Exception e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
return SUCCESS;
}

@Override
public void Setservletrequest (HttpServletRequest request) {
TODO auto-generated Method Stub
