使用 Spring Web 服务客户端解密消息
350 赏金和华夫饼送给可以帮助我的人!
我已经在 Spring Web 服务加密方面苦苦挣扎了好几天,但我不知道如何解决让 Spring 对消息正文的加密发挥作用。每当我让服务器加密生成的消息时,客户端在尝试根据架构验证它之前似乎不会解密它(XSD)。
我能做的就是加密用户令牌并成功解密。我在从客户端向服务器发送数据时这样做。然后,服务器解密用户令牌并验证用户凭据,效果非常好。
如果我尝试加密返回的消息正文,就会出现问题。该问题发生在客户端。客户端似乎试图在解密之前验证消息,因此在根据架构进行验证时会发生错误。

我知道它有很多信息,但我想我会提供所有内容。我的加密设置正确吗?是否不可能加密消息正文并在客户端解密?在这一点上,我几乎愿意接受任何建议。

看看 中)。例如设置:
CastorMarshaller
属性,并尝试将一些“忽略”属性设置为 true(在您的其中之一可能会做到这一点。
Take a look at
CastorMarshaller
properties, and attempt setting some of the "ignoring" ones to true (in your<bean id="castorMarshaller"
). For example set:One of those might do it.
您确定
得到妥善解决吗?
您收到的错误表明它无法找到如何处理该元素。如果响应未解密,您将看不到元素名称和前缀。
您是否能够在不加密的情况下验证和运行 Web 服务?
Are you certain
is being resolved properly?
The error you're getting indicates it can't find how to handle that element. You wouldn't be seeing the element name and prefix if the response wasn't getting decrypted.
Are you able to validate and run the web service without encryption?
