[spring] Injection of autowired dependencies failed;

I am developing a small Java EE Hibernate Spring application and an error appeared:
Error creating bean with name 'articleControleur': Injection of autowired dependencies failed;

And here is my controller ArticleControleur which contains a function for recovering the lists of articles:

package com.bd.controleur;

import java.util.HashMap;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.bd.service.ArticleService;

@Controller
@RequestMapping("/Article/GererArticle")
public class ArticleControleur {

    @Autowired
    ArticleService articleService;

    public ModelAndView listarticle() {

    Map<String, Object> model = new HashMap<String, Object>();
    model.put("articles", articleService.getAllArticles());

    // new ModelAndView("nom de la page jsp", model qui contient l'ensemble
    // des beans que tu vas passer a cette page)
    return new ModelAndView("GererArticle", model);

    }

}

And here is my articleService: 

package com.bd.service;

import java.util.Collection;
import java.util.List;

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

import com.bd.dao.ArticleDao;
import com.bd.entity.Article;

@Service
public class ArticleServiceImp implements ArticleService {

    @Autowired
    private ArticleDao articledao;



    @Override
    public Article getArticleById(int articleId) {
        // TODO Auto-generated method stub
        return articledao.getById(articleId);
    }

    @Override
    public void saveArticle(Article article) {
        // TODO Auto-generated method stub
        articledao.save(article);

    }

    @Override
    public void deleteArticle(Article article) {
        // TODO Auto-generated method stub
        articledao.delete(article);
    }

    @Override
    public List<Article> getAllArticles() {
        // TODO Auto-generated method stub
        return articledao.getAll();
    }

}

And here is my application context:

This question is related to spring autowired

The answer is

Do you have a bean declared in your context file that has an id of "articleService"? I believe that autowiring matches the id of a bean in your context files with the variable name that you are attempting to Autowire.

public class Organization {

    @Id
    @Column(name="org_id")
    @GeneratedValue
    private int id;

    @Column(name="org_name")
    private String name;

    @Column(name="org_office_address1")
    private String address1;

    @Column(name="org_office_addres2")
    private String address2;

    @Column(name="city")
    private String city;

    @Column(name="state")
    private String state;

    @Column(name="country")
    private String country;

    @JsonIgnore
    @OneToOne
    @JoinColumn(name="pkg_id")
    private int pkgId;

    public int getPkgId() {
        return pkgId;
    }

    public void setPkgId(int pkgId) {
        this.pkgId = pkgId;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    @Column(name="pincode")
    private String pincode;

    @OneToMany(mappedBy = "organization", cascade=CascadeType.ALL, fetch = FetchType.EAGER)
    private Set<OrganizationBranch> organizationBranch = new HashSet<OrganizationBranch>(0);

    @Column(name="status")
    private String status = "ACTIVE";

    @Column(name="project_id")
    private int redmineProjectId;

    public int getRedmineProjectId() {
        return redmineProjectId;
    }

    public void setRedmineProjectId(int redmineProjectId) {
        this.redmineProjectId = redmineProjectId;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public Set<OrganizationBranch> getOrganizationBranch() {
        return organizationBranch;
    }

    public void setOrganizationBranch(Set<OrganizationBranch> organizationBranch) {
        this.organizationBranch = organizationBranch;
    }

    public int getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress1() {
        return address1;
    }

    public void setAddress1(String address1) {
        this.address1 = address1;
    }

    public String getAddress2() {
        return address2;
    }

    public void setAddress2(String address2) {
        this.address2 = address2;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }

    public String getPincode() {
        return pincode;
    }

    public void setPincode(String pincode) {
        this.pincode = pincode;
    }
}

You change the private int pkgId line in change datatype int to primitive class name or add annotation @autowired
