Answer 1

看来你需要调试encry增加了XML元素。你可以检查document.getDocumentElements()的内容是正确的XML？

我想这是空。从上面的函数成功拿到原始的XML元素后，就可以解密XML为纯文本。例如，这个网站SAML Assertion Decryption - SAML Decrypt XML Tool - Decrypt SAML Response

Answer 2

好吧，似乎是两件事情错了。

它看起来像你不小心试图解密响应对象，而不是包含断言。你应该这样做

Response response = unmarshaller.unmarshall(...); 
return (EncryptedAssertion) response.getEncryptedAssertions().get(0) 

只要你知道在响应中只发送一个断言。

但是，你似乎得到了SAML 1响应消息而不是SAML 2. 我不是SAML 1的专家，但似乎不支持encryptet断言。

因此，首先将protocoll版本与发送消息的版本进行排序，然后确保返回加密的断言而不是响应对象。
