服务注入在托管bean中使用@Inject失败

Question

我有一个maven Java应用程序，其中包含（模型，服务和UI）的不同项目。 我试图在UIBean.java文件中注入服务。但是它没有这样做并且给出了服务为空的错误。

以下是UIBean.java的代码

package com.test.testhr.ui;

import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;
import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.test.testhr.model.User;
import com.test.testhr.service.authentication.ILogInService;

@ManagedBean(name = "loginUIBean")
@Component
@SessionScoped
@Transactional(propagation = Propagation.REQUIRES_NEW)
public class LoginUIBean {

    private String username;

    private String password;

    private String messages = new String("");

    @Inject
    private transient ILogInService logInService;

    public void login(ActionEvent actionEvent) {
        User user = new User();
        user.setUsrName(username);
        user.setUsrPasswd(password);

        try {
            user = logInService.validate(user);
            if (null != user) {
                HttpSession httpSession = (HttpSession) FacesContext
                        .getCurrentInstance().getExternalContext()
                        .getSession(false);
                httpSession.setAttribute("user", user);
                FacesContext.getCurrentInstance().getExternalContext()
                        .redirect("default.xhtml");
            }
        } catch (Exception ex) {
            messages = "Please provide valid user name and password";
            FacesContext.getCurrentInstance().addMessage(
                    null,
                    new FacesMessage(FacesMessage.SEVERITY_ERROR,
                            "Failure Message", messages));
        }
    }

然而，当程序来到logInService时。它发现它为空，因为注射没有发生。

有人可以帮忙吗？

更新：我的项目中没有faces-config.xml。这可能是个问题吗？ 我的web.xml如下：
