Hibernate 3和Struts 2实现Jasypt时出错 [英] Error implementing Jasypt with Hibernate 3 and Struts 2
问题描述
我试图使用Jasypt和hibernate 3加密webapp中的密码。我按照 这是我的hibernate映射： 现在我每次使用hibernate打开会话时注册加密器： 然后，每次尝试访问用户时，都会抛出以下异常： 任何人都有想法用Hibernate 3和Struts 2实现jasypt还是可以帮我解决这个错误？ （我必须使用jasypt） 没关系，问题是映射中的加密器注册名称： 当我注册它时，我会在名称中添加String： 必须设置密码： 现在不再有错误。 （我编辑上面的代码以反映更改） I'm trying to encrypt passwords in a webapp using Jasypt with hibernate 3. I followed the instructions on the jasypt website. Here's my hibernate mapping : Now I register the encryptor each time I open a session with hibernate : Then, each time I try to access a user, this exception is thrown : Anybody have an idea for implementing jasypt with Hibernate 3 and Struts 2 or can help me with this error ? (I have to use jasypt) It's ok, the problem was the encryptor registered name in the mapping : When I registered it, I add "String" in the name : Have to set a password too : No more error now. (I edit my code above to reflect the changes) 这篇关于Hibernate 3和Struts 2实现Jasypt时出错的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
