Spring preventing me from authorizing my class
I have a search for a similar question but cannot find anything on this issue.
This is my controller class
@Controller
@RequestMapping(value = "/admin")
public class AdminController {
@Autowired
private AuthenticationServicesImpls check;
public AuthenticationServicesImpls getCheck() {
return check;
}
public void setCheck(AuthenticationServicesImpls check) {
this.check = check;
}
@RequestMapping(value = "/login")
public ModelAndView adminLogin(HttpServletResponse response)
throws IOException {
return new ModelAndView("adminlogin");
}
@RequestMapping(value = "/authentication")
public ModelAndView validateAdmin(HttpServletResponse response,
@RequestParam(value = "userid", required = false) String username,
@RequestParam(value = "password", required = false) String password){
System.out.print(username);
System.out.print(password);
if(check.validateAdminUser(username, password)){
return new ModelAndView("adminlogin");
} else
{
return new ModelAndView("error/errorlogin");
}
}
}
This is my service interface
package online.services;
import org.springframework.stereotype.Repository;
@Repository
public interface AuthenticationServices {
public boolean isLoggedIn();
public int login();
public int logout();
public boolean validateUser();
}
This is my implementation of the DOE class. I just used a test-only method
package online.deo;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import online.model.UserDetail;
import online.services.AuthenticationServices;
@Transactional
@Repository
@Component
public class AuthenticationServicesImpls implements AuthenticationServices {
AuthenticationServicesImpls(){}
@Autowired
private SessionFactory sessionFactory;
public boolean validateUser() {
return false;
}
@SuppressWarnings("unchecked")
@Transactional(readOnly = true)
public boolean validateAdminUser(String userID, String password) {
System.out.print("this is session facoty class"+ sessionFactory.toString());
System.out.print(userID);
System.out.print(password);
Session session = sessionFactory.openSession();
System.out.println(session);
Query query = session.createQuery("from user_detail");
System.out.println(query.list());
List<UserDetail> user = query.list();
if (user != null) {
for (UserDetail us : user) {
System.out.println(us.getUser_id());
if (us.getUser_username().equals(userID)) {
if (us.getUser_password().equals(password)) {
return true;
}
return false;
}
}
}
return false;
}
}
This is my POJO class
package online.model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.EnumType;
import javax.persistence.Enumerated;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "user_detail")
public class UserDetail {
@Id
private int user_id;
@Column(name = "user_first_name")
private String user_first_name;
@Column(name = "user_last_name")
private String user_last_name;
@Column(name = "user_emailid")
private String user_emailid;
@Column(name = "user_mobileno")
private long user_mobileno;
@Column(name = "user_username")
private String user_username;
@Column(name = "user_password")
private String user_password;
@Enumerated(EnumType.STRING)
private Role user_role;
public int getUser_id() {
return user_id;
}
public void setUser_id(int user_id) {
this.user_id = user_id;
}
public String getUser_first_name() {
return user_first_name;
}
public void setUser_first_name(String user_first_name) {
this.user_first_name = user_first_name;
}
public String getUser_last_name() {
return user_last_name;
}
public void setUser_last_name(String user_last_name) {
this.user_last_name = user_last_name;
}
public String getUser_emailid() {
return user_emailid;
}
public void setUser_emailid(String user_emailid) {
this.user_emailid = user_emailid;
}
public long getUser_mobileno() {
return user_mobileno;
}
public void setUser_mobileno(long user_mobileno) {
this.user_mobileno = user_mobileno;
}
public String getUser_username() {
return user_username;
}
public void setUser_username(String user_username) {
this.user_username = user_username;
}
public String getUser_password() {
return user_password;
}
public void setUser_password(String user_password) {
this.user_password = user_password;
}
public Role getUser_role() {
return user_role;
}
public void setUser_role(Role user_role) {
this.user_role = user_role;
}
}

I don't understand why my application is not getting auto-update.

By default, Spring uses standard java front-end proxies. This means that your Spring managed beans must implement Spring interfaces.
If you want a class based proxy, you can update the following annotation in your Config app (I believe this also requires a CGLIB jar):
Note the "proxyTargetclass = true":
@EnableAspectJAutoProxy(proxyTargetClass = true)

Change
@Autowired
private AuthenticationServicesImpls check;
public AuthenticationServicesImpls getCheck() {
return check;
}
public void setCheck(AuthenticationServicesImpls check) {
this.check = check;
}
To:
@Autowired
private AuthenticationServices check;
public AuthenticationServices getCheck() {
return check;
}
public void setCheck(AuthenticationServices check) {
this.check = check;
}
This should work.
