Question

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

我的问题是UserLoginDAOImpl类的方法loadUserByName（String name）没有加载持久的角色集。

我使用Netbeans 7.3 beta IDE，Glassfish服务器3+作为网络服务器。

以下是调试快照。 Here is the Debugging snapshot

以下是hbm查询的调试跟踪：

INFO: Hibernate: select users0_.USERS_ID as USERS1_2_, users0_.USERS_USERNAME as USERS2_2_, users0_.USERS_PASSWORD as USERS3_2_, users0_.USERS_ENABLED as USERS4_2_, users0_.USERS_CREATED_DT as USERS5_2_, users0_.USERS_MODIFIED_DT as USERS6_2_, users0_.USERS_EMAIL as USERS7_2_ from ats.users users0_ where users0_.USERS_USERNAME='user'
INFO: Hibernate: select roleses0_.ROLES_USERNAME as ROLES2_1_, roleses0_.ROLES_ID as ROLES1_1_, roleses0_.ROLES_ID as ROLES1_1_0_, roleses0_.ROLES_USERNAME as ROLES2_1_0_, roleses0_.ROLES_ROLE_NAME as ROLES3_1_0_, roleses0_.ROLES_CREATED_DT as ROLES4_1_0_, roleses0_.ROLES_MODIFIED_DT as ROLES5_1_0_ from ats.roles roleses0_ where roleses0_.ROLES_USERNAME=?

用户和角色表架构：

CREATE TABLE `users` (

USERS_ID int（11）NOT NULL AUTO_INCREMENT， USERS_USERNAME varchar（45）NOT NULL， USERS_PASSWORD varchar（255）NOT NULL， USERS_ENABLED varchar（5）NOT NULL， USERS_CREATED_DT varchar（45）NOT NULL， USERS_MODIFIED_DT varchar（45）DEFAULT NULL， USERS_EMAIL varchar（50）DEFAULT NULL， PRIMARY KEY（USERS_ID），独特的钥匙USERS_USERNAME_UNIQUE（USERS_USERNAME））ENGINE = InnoDB AUTO_INCREMENT = 3 DEFAULT CHARSET = utf8 $$

CREATE TABLE `roles` (

ROLES_ID int（11）NOT NULL AUTO_INCREMENT， ROLES_USERNAME varchar（45）NOT NULL， ROLES_ROLE_NAME varchar（45）NOT NULL， ROLES_CREATED_DT varchar（45）NOT NULL， ROLES_MODIFIED_DT varchar（45）DEFAULT NULL， PRIMARY KEY（ROLES_ID）， KEY FK_ROLES_ID（ROLES_USERNAME）， CONSTRAINT FK_ROLES_ID FOREIGN KEY（ROLES_USERNAME）引用users（USERS_USERNAME）ON更新没有操作更新无操作）ENGINE = InnoDB AUTO_INCREMENT = 4 DEFAULT CHARSET = utf8 $$

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班中尝试：

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

hibernate持久化集不会在一对多映射中填充
