hibernate持久集未在一对多映射中填充

我正在尝试使用Spring、Hibernate和JSF创建一个用户管理系统。我创建了自己的Users类，它实现java.io.Serializable，org.springframework.security.core.userdetails.userdetails 和角色类

我的问题是UserLoginDAOImpl类的loadUserByName（字符串名）方法没有加载持久的角色集。

我正在使用Netbeans 7.3 beta IDE，Glassfish server 3+作为web服务器

这是调试快照。

以下是hbm查询的调试跟踪：

用户和角色表架构：

这是我的DAOImpl类方法：

 @Override
public Users loadUserByName(String name) {
    if (name != null && !name.equals("")) {
                Session session=hibernateTemplate.getSessionFactory().openSession();
                Transaction transaction=null;
                transaction=session.beginTransaction();
                
                 List<Users> user=session.createQuery("from Users where usersUsername='"+name+"'").list();
            
                
             
       
                 
                   transaction.commit();
                    if (user.size() == 1) {
                 
            
                     return user.get(0);
        } else {
            return null;
        }
    } else {
        return null;
    }
}

请告诉我如何解决此问题。

在Dao类中，请尝试：

 List<Users> user=
     session.createQuery("from Users u where u.usersUsername= :username")
    .setParameter("username", name).list();

列出用户=
createQuery（“来自用户u，其中u.usersUsername=：用户名”）
.setParameter（“用户名”，名称）.list（）；

我已经试过了：

List user=session.createQuery（“从用户身份u，其中u.usersUsername=：username”）.setParameter（“username”，name）.List（）但设置角色具有空值。
