Your spring-servlet.xml says

while the UserDao component is not in the controller package.

(edited from a previous version)
I created a simplified setting for your problem, and got the code to work.
Here are the two Java classes, first the service (in essense a stub, I did not try to simplify it further, the code has no particular significance):
package com.anzy.services;
import java.util.ArrayList;
import java.util.Collection;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
#Service("userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService
{
#Transactional(readOnly=true)
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException
{
Collection <GrantedAuthority> authorities=new ArrayList<GrantedAuthority>();
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
org.springframework.security.core.userdetails.User secureUser=new org.springframework.security.core.userdetails.User("user", "user", true, true, true, true, authorities);
return secureUser;
}
}
and here is the controller (again, simplified to have just one method)
package com.anzy.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class DataController {
#RequestMapping("form")
public ModelAndView getForm() {
return new ModelAndView("form");
}
}
the four files under WEB-INF are:

then I get precisely the exception which was the subject of your question

Spring 4.3.0.RELEASE + Hibernate 5.2.0.Final - Could not obtain transaction-synchronized Session for current thread

Hi,
I got this error and i can`t figure why? all of the defintions in there place and still i have this error while i trying to insert data to my DB.
the "tx:annotation-driven" is in the appconfig-data.xml
I call the add function from "UserController"
What could be the reason it does not work?
Error log:

You are using non transactional daos in your UserController.registration method:
roleDAO.add(roleUser);
roleDAO.add(roleAdmin);
Use RoleServiceImpl instead.

I've read in a lot of posts that it's to do with not setting annotations on fields and getters at the same time. But as you can see that's not the cause here. I'm stumped.

Also I've just tried using #ManyToOne on the sender and receiver getters. But this didn't make any difference.

You haven't mapped the message to whore relationship inside message. Should be:
#ManyToOne
public Whore getSender() {
return sender;
}
#ManyToOne
public Whore getReceiver() {
return receiver;
}
Comment : You shouldn't annotate / use your entity as #Component

You should remove the leading slash ("/") character from your <context:component-scan> tags, and the packagesToScan property of your sessionFactory should be *, not /.

Spring Framework - Hibernate

I am going to be confused. I am trying to get Hibernate work with Spring, I can not get rid of a BeanCreationException. Please help me. I am new to Spring (and also Hibernate).
The problem is caused in a controller, having a private attribute userService which is annotated with #Autowired.

}
I would really appreciate it if somebody could help me, i am going to be desperate...

Add the service class package to the component-scan base-package list in the application context file
<context:component-scan
base-package="
com.aerts.controller
com.aerts.service">
</context:component-scan>

I'm not expertise in spring but I assume that you have a problem with your service, if you use an interface you should inject ut and not your class...
see this track...
Spring expected at least 1 bean which qualifies as autowire candidate for this dependency

We Keep Coding

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Component annotation is not working properly - java

Your spring-servlet.xml says <context:component-scan base-package="com.vc.teacher.controller" /> while the UserDao component is not in the controller package.
