用Hibernate 3和Struts 2实现Jasypt时出错

我想用jasypt和hibernate 3来加密webapp中的密码。我按照jasypt website上的说明操作。用Hibernate 3和Struts 2实现Jasypt时出错

这里是我的Hibernate映射：

<hibernate-mapping package="webapp.entity"> 

    <typedef name="encrypted" class="org.jasypt.hibernate.type.EncryptedStringType"> 
    <param name="encryptorRegisteredName">strongHibernateStringEncryptor</param> 
    </typedef> 

    <class name="User" table="Users"> 
    <id name="name" 
     column="name" 
     type="string"> 
    </id> 

    <property name="passwd" 
     column="passwd" 
     type="encrypted" 
     not-null="true"> 
    </property> 

    </class> 

</hibernate-mapping>

现在我每次我打开与Hibernate会话时间注册加密：

public void initHibSession() { 
    HibernateUtil.buildSessionFactory(); 
    hib_session = HibernateUtil.getSessionFactory().getCurrentSession(); 
    if (hib_session != null && hib_session.isOpen()) { 
     hib_session.close(); 
     hib_session = HibernateUtil.getSessionFactory().openSession(); 
    } 
    hib_session.beginTransaction(); 

    StandardPBEStringEncryptor strongEncryptor = new StandardPBEStringEncryptor(); 
    strongEncryptor.setPassword("aStrongPassword"); 
    HibernatePBEEncryptorRegistry registry = HibernatePBEEncryptorRegistry.getInstance(); 
    registry.registerPBEStringEncryptor("strongHibernateStringEncryptor", strongEncryptor); 
}

然后，每次我试图访问用户，此异常抛出：

FreeMarker template error!

任何人都有一个想法与Hibernate 3实现jasypt和d Struts 2还是可以帮我解决这个错误？（我不得不使用jasypt）

这没关系，问题是在映射的加密注册名称：

<param name="encryptorRegisteredName">strongHibernateEncryptor</param>

当我注册的，我的名字加上“字符串”：

registry.registerPBEStringEncryptor("strongHibernateStringEncryptor", strongEncryptor);

必须设置密码太：

strongEncryptor.setPassword("aStrongPassword");

没有更多的错误了。

（编辑我上面的代码以反映更改）

你应该知道，休眠/ jaspyt加密是基于PBE和可逆的，也就是说，它的数据库中的唯一加密，而不是在应用程序。

尤其对于密码，最好使用不可逆的基于摘要的加密 - StrongPasswordEncryptor实际上是您在上述情况下应该使用的。

我终于没有使用这个密码加密的原因你提到，我用这个加密数据我需要检索后，所以可逆性是必要的。 – codea 2011-03-31 17:49:21
