No EntityManager with actual transaction available for current thread - cannot reliably process 'persist' call

Question

No EntityManager with actual transaction available for current thread - cannot reliably process 'persist' call

when I do a test with JUnit, persist method works and I see that my object is inserted, but when I call the method via my Controller doesn't work

here is my Project :

my Model Class:

package com.app.sqli.models;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class Collaborateur {

    @Id
    private int id;
    private String nom;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getNom() {
        return nom;
    }

    public void setNom(String nom) {
        this.nom = nom;
    }

}

my DAO Class

package com.app.sqli.dao;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.springframework.stereotype.Repository;

import com.app.sqli.models.Collaborateur;

@Repository
public class CollaborateurDao implements IcollaborateurDao{

    @PersistenceContext
    private EntityManager em;

    @Override
    public void addCollaborateur(Collaborateur c) {
    em.persist(c);

    }

}

My Service Class

package com.app.sqli.services;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.app.sqli.dao.IcollaborateurDao;
import com.app.sqli.models.Collaborateur;

@Service
@Transactional
public class CollaborateurService implements IcollaborateurService{

    @Autowired
    private IcollaborateurDao cdao;

    @Override
    public void addCollaborateur(Collaborateur c) {
        cdao.addCollaborateur(c);

    }


}

And My Controller

package com.app.sqli.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.app.sqli.models.Collaborateur;
import com.app.sqli.services.IcollaborateurService;

@org.springframework.stereotype.Controller
public class Controller {
    @Autowired
    private IcollaborateurService cserv;

    @RequestMapping(value = "/index")
    public String index(Model m) {
        System.out.println("insertion ...");
        Collaborateur c = new Collaborateur();
        c.setId(11);
        c.setNom("nom");
        cserv.addCollaborateur(c);
        return "index";
    }

}

thank you @mechkov for your time and help, My problem is resolved by changing my configuration file, so I have used a Configuration Class with annotations and its works so fine, I still Don't know where the problem was

    @Configuration
    @ComponentScan(basePackages = "your package")
    @EnableTransactionManagement
    public class DatabaseConfig {

        protected static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";
        protected static final String PROPERTY_NAME_DATABASE_PASSWORD = "password";
        protected static final String PROPERTY_NAME_DATABASE_URL = "jdbc:mysql://localhost:3306/databasename";
        protected static final String PROPERTY_NAME_DATABASE_USERNAME = "login";

        private static final String PROPERTY_PACKAGES_TO_SCAN = "where your models are";
        @Bean
        public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter){
            LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
            entityManagerFactoryBean.setDataSource(dataSource);
            entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
            entityManagerFactoryBean.setPackagesToScan(PROPERTY_PACKAGES_TO_SCAN);
            return entityManagerFactoryBean;
        }

        @Bean
        public BasicDataSource dataSource(){
            BasicDataSource ds = new BasicDataSource();
            ds.setDriverClassName(PROPERTY_NAME_DATABASE_DRIVER);
            ds.setUrl(PROPERTY_NAME_DATABASE_URL);
            ds.setUsername(PROPERTY_NAME_DATABASE_USERNAME);
            ds.setPassword(PROPERTY_NAME_DATABASE_PASSWORD);
            ds.setInitialSize(5);
            return ds;
        }

        @Bean
        public JpaVendorAdapter jpaVendorAdapter(){
            HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
            adapter.setDatabase(Database.MYSQL);
            adapter.setShowSql(true);
            adapter.setGenerateDdl(true);

//I'm using MySQL5InnoDBDialect to make my tables support foreign keys
adapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect");
            return adapter;
        }

        @Bean
        public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
            return new JpaTransactionManager(entityManagerFactory);
        }


    }
