I’m still new to Spring MVC and while building my test project, I got this message from Tomcat logs:
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

I have two rolle services for user and admin with there interfaces:
package employee.service;
import employee.model.EmployeeDiv;
import employee.model.EmployeeInfo;
import employee.model.UserInfo;
import java.util.List;
/**
*
* @author serge
*/
public interface AdminService extends UserService {
// !!!! for register & udate of Employee use String type birthday !!!!
/*
* Employee
*/
public EmployeeInfo registerEmployee(EmployeeInfo employeeInfo);
public EmployeeInfo updateEmployee(EmployeeInfo employeeInfo);
public EmployeeInfo findEmployeeByID(Integer id);
/*
* Division
*/
public EmployeeDiv registerDivision(EmployeeDiv division);
public EmployeeDiv updateDivision(EmployeeDiv division);
public List<EmployeeDiv> findAllDivisions();
public List<EmployeeDiv> findDivisionsByName(EmployeeDiv division);
public EmployeeDiv findDivisionsById(Integer id);
/*
* Login
*/
public UserInfo registerUser(UserInfo user);
public UserInfo updateUser(UserInfo user);
public List<UserInfo> findAllUsesrs();
public List<UserInfo> findUsesrByLogin(UserInfo user);
public UserInfo findUsesrById(Integer id);
}

Please tell me what is the problem with this bean name, I understand that is AOP problem:
Bean named 'adminService' must be of type [employee.service.impl.AdminServiceImpl], but was actually of type [$Proxy52]
how I can fix it?
I use AdminServiceImpl in Controllers:
package employee.controller;
import employee.model.EmployeeDiv;
import employee.service.impl.AdminServiceImpl;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import javax.annotation.Resource;
/**
* @author serge
*
* Handles and retrieves division related requests
*/
@Controller
@RequestMapping("/division")
public class DivisionController {
protected static Logger logger = Logger.getLogger("controller");
@Resource(name = "adminService")
private AdminServiceImpl adminService;
/**
* Handles and retrieves a /WEB-INF/jsp/divisionpage.jsp
*
* containing all division
*
* @return the name of the JSP page
*/
@RequestMapping(method = RequestMethod.GET)
public String getAllPage(Model model) {
logger.debug("Received request to show all division page");
// Retrieve all division and attach to model
model.addAttribute("division", adminService.findAllDivisions());
return "divisionpage";
} ....
Somewhere in your code you must be autowiring
AdminServiceImpllike this:Either depend barely on interface:
or enabled CGLIB proxies.
