org.springframework.beans.NotWritablePropertyException in Spring project

Question

I'm trying to create a Spring Project with CRUD operation. I'm new to Spring, So I need a bit of help-

I'm getting a following error on submitting the form with post method-

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'userDao' of bean class [com.cjc.service.RegistrationServiceImpl]: Bean property 'userDao' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter? at org.springframework.beans.BeanWrapperImpl.createNotWritablePropertyException(BeanWrapperImpl.java:231) at org.springframework.beans.AbstractNestablePropertyAccessor.setPropertyValue(AbstractNestablePropertyAccessor.java:423) at org.springframework.beans.AbstractNestablePropertyAccessor.setPropertyValue(AbstractNestablePropertyAccessor.java:280) at org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:95) at org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:75) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1514) ... 47 more

Please find below the java files for the same-

Controller-

package com.cjc.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.cjc.model.User;
import com.cjc.service.RegistrationService;

@Controller
public class RegistrationController {
    @Qualifier("regservice")
    private RegistrationService registrationService;

    public void setRegistrationService(RegistrationService registrationService) {
        this.registrationService = registrationService;
    }

    @RequestMapping(value="/registration", method=RequestMethod.POST)
    public String Registration(@ModelAttribute User u) {
        registrationService.addPerson(u);

        return "RegSuccess";
    }
}

Service-

package com.cjc.service;

import com.cjc.dao.UserDAO;
import com.cjc.model.User;

public class RegistrationServiceImpl implements RegistrationService {

    private UserDAO userDao ;

    public void setUserDao(UserDAO userDao) {
        this.userDao = userDao;
    }



    @Override
    public int addPerson(User u) {
        // TODO Auto-generated method stub

        return 0;
    }

}

DAO Impl-

package com.cjc.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

import com.cjc.model.User;
import com.cjc.util.HibernateUtil;

public class UserDaoImpl implements UserDAO{

    @Override
    public void addUser(User u) {
        // TODO Auto-generated method stub
        SessionFactory sessionFactory=HibernateUtil.getSessionFactory();
        Session session=sessionFactory.openSession();
        Transaction transaction=session.beginTransaction();

        session.save(u);

        transaction.commit();
    }

    @Override
    public void deleteUser(int id) {
        // TODO Auto-generated method stub

    }

    @Override
    public List<User> getAllUser() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public User getUserById(int id) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void updteUser(User u, int id) {
        // TODO Auto-generated method stub

    }

}

Please help me in resolving the issue

Can you show your getter method? The error message is very clear Bean property 'userDao' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter — buræquete

You missing setter and getter in User Model. Add setter and getter.
