hibernate持久集不填充一對多映射

我想創建一個使用Spring，Hibernate和JSF的用戶管理系統。我創建了自己的Users類，它實現了java.io.Serializable，org.springframework.security.core.userdetails.UserDetails 和Roles類。hibernate持久集不填充一對多映射

我的問題是UserLoginDAOImpl類的方法loadUserByName（String name）不加載持久性角色集。

我使用Netbeans 7.3 beta IDE，Glassfish server 3+作爲web服務器。

這裏是調試快照。Here is the Debugging snapshot

這裏是HBM查詢的調試跟蹤：

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=?

用戶和角色表模式：

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）， UNIQUE KEY USERS_USERNAME_UNIQUE（USERS_USERNAME））ENGINE = InnoDB的AUTO_INCREMENT = 3默認字符集= 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）約束FK_ROLES_ID外鍵（ROLES_USERNAME）參考文獻users（USERS_USERNAME）ON DELETE NO ACTION ON UPDATE NO ACTION ）ENGINE = InnoDB的AUTO_INCREMENT = 4默認字符集= UTF8 $$

這是我的DAOImpl類方法：

@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; 
    } 
}

}

請告訴我如何解決此問題。

在DAO類的嘗試：

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

我已經嘗試過了，得到同樣的結果。 :( –

我試過了：'List user = session.createQuery（「from Users as u，where u.usersUsername =：username」）。setParameter（「username」，name）.list（）;'但是設置角色有空值。 –
