Question

代码显示我想创建一个以会话为范围的loginBean。我也将显示applicationContext以及service和dao，因为它们中可能还存在配置错误。

我注意到我的所有bean都是作为应用程序作用域处理的。（跑完项目并登录并在标题上显示我的用户名。然后我打开另一个浏览器，转到我的localhost并填写了用户名..）

有人有任何想法吗？

login服务：

package be.neoria.swissknife.service;
import be.neoria.swissknife.model.Consultant;

/**
 * Created with IntelliJ IDEA.
 * User: Greg
 * Date: 29/03/13
 * Time: 12:09
 * To change this template use File | Settings | File Templates.
 */
public interface LoginService {
    public Consultant loginConsultant(String username, String password);
}

loginService实现：

package be.neoria.swissknife.service;

import be.neoria.swissknife.dao.ConsultantDao;
import be.neoria.swissknife.model.Consultant;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
 * Created with IntelliJ IDEA.
 * User: Greg
 * Date: 29/03/13
 * Time: 12:10
 * To change this template use File | Settings | File Templates.
 */
@Transactional
@Service("loginService")
public class LoginServiceImpl implements LoginService {

@Autowired
ConsultantDao consultantDao;

@Override
public Consultant loginConsultant(String username, String password) {
    Consultant consultant = consultantDao.getConsultantByName(username);
    if (consultant.getPaswoord().equals(password)) {
        return consultant;
    } else {
        return null;
    }

}

consultantDao：

    package be.neoria.swissknife.dao;

import be.neoria.swissknife.model.Adres;
import be.neoria.swissknife.model.Consultant;
import java.util.List;

/**
 * Created with IntelliJ IDEA. User: Greg Date: 29/03/13 Time: 12:18 To change
 * this template use File | Settings | File Templates.
 */
public interface ConsultantDao {

    public Consultant getConsultantByName(String name);
}

consultantDaoImpl：

package be.neoria.swissknife.dao;


import be.neoria.swissknife.model.Adres;
import be.neoria.swissknife.model.Consultant;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

/**
 * Created with IntelliJ IDEA.
 * User: Greg
 * Date: 29/03/13
 * Time: 12:18
 * To change this template use File | Settings | File Templates.
 */
@Repository
public class ConsultantDaoImpl implements ConsultantDao {

@Autowired
private SessionFactory sessionFactory;

@Override
public Consultant getConsultantByName(String name) {
    Query query = sessionFactory.getCurrentSession().createQuery("from Consultant where naam=:name");
    query.setParameter("name", name);

    return (Consultant) query.uniqueResult();

    }

}

Answer 1

尝试

@Component
@Scope(value = "request")

而不是@SessionScoped

Bean范围不起作用
