无法使用Java SoapMessage更改信封中的soap URI [英] Cannot change soap URI in envelope using java SoapMessage

问题描述

我正在尝试创建一个简单的SOAP消息以从客户端发送，但是(似乎)无法更改信封中"soap"名称空间的URI.

I'm trying to create a simple SOAP message to send from a client, but I am (seemingly) unable to change the URI of the "soap" namespace in the envelope.

soap header应该是这样的:

This is what the soap header SHOULD look like:

<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope/"  soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding/"> ... </soap:Envelope>

所以我有以下代码:

    final SOAPMessage sm = MessageFactory.newInstance().createMessage();

    final SOAPPart sp = sm.getSOAPPart();
    final SOAPEnvelope se = sp.getEnvelope();
    final SOAPHeader sh = se.getHeader();
    final SOAPBody sb = se.getBody();

    se.removeNamespaceDeclaration(se.getPrefix());
    se.addNamespaceDeclaration("soap", "http://www.w3.org/2001/12/soap-envelope");
    se.setPrefix("soap");
    sb.setPrefix("soap");
    sh.setPrefix("soap");
    se.setEncodingStyle("http://www.w3.org/2001/12/soap-encoding/");

但是，当我在发送前打印邮件时，以下是我的信封:

However, when I print the message before sending, the following is my envelope:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding/">

请注意应该"部分中xmlns:soap的URI与实际URI中的区别.

Notice the differences in the URIs of xmlns:soap in the "should-be" section and the actual.

如果我将 addNamespaceDeclaration 调用的第一个参数更改为"soapy"而不是"soap"，则得到以下信封:

If I change the first argument of the addNamespaceDeclaration call to "soapy" instead of "soap", this is the following envelope I get:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soapy="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding/">

我猜这可能与调用为 addNamespaceDeclaration 而不是诸如 changeNamespaceDeclaration 之类的事实有关，并且考虑到命名空间已被忽略目前，但是我找不到有效的方法(我已经尝试过 setAttributeNS ).

I'm guessing it may have something to do with the fact that the call is addNamespaceDeclaration rather than something like changeNamespaceDeclaration, and it is ignored considering the namespace is already present, but I cannot find something that works (I've already tried setAttributeNS).

我刚刚意识到 setAttributeNS 是愚蠢的，因为这改变了名称空间，而不是URI.再次我有点困惑，当我继续搜索时，有时会看到命名是 soap:"Namespace" ，所以从这个意义上讲，我确实想更改命名空间...但是我以为命名空间是肥皂"的一部分.有任何澄清吗?

I just realized that setAttributeNS is silly because that's changing the namespace, not the URI. EDIT AGAIN: I'm a little confused, as I continue to search I see sometimes that the naming goes soap:"Namespace", so in that sense I do want to change the namespace... but I thought the namespace was the "soap" part. Any clarifications?

这是我的第一篇文章，因此，如果我要问的是已经解决的问题，我深表歉意，但是我四处搜寻，发现的大部分内容都与更改名称空间有关(例如，从SOAP-ENV，这是默认的名称空间，而不是URI本身.预先感谢.

This is my first post so I apologize if I'm asking something that has already been solved, but I've searched around and most of what I've found is related to changing the namespace (like from SOAP-ENV, which is the default namespace, to soap) rather than the URI itself. Thanks in advance.

推荐答案

通常，您不需要手动修改SOAP名称空间.您可能想要实现的是创建一个SOAP 1.2消息(它的名称空间与SOAP 1.1不同).尝试从代码中删除所有更改名称空间的行，并将第一行更改为

In general you should not need to manually modify the SOAP namespace. What you probably want to achieve is to create a SOAP 1.2 message (which has a different namespace than SOAP 1.1). Try removing all namespace altering lines from your code and change the first line to

final SOAPMessage sm = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage();

如果您确实需要指定应使用的前缀，则此代码似乎有效:

In case you REALLY need to specify which prefix that should be used, this code seems to work:

SOAPMessage sm = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage();
sm.getSOAPPart().getEnvelope().setPrefix("soap");
sm.getSOAPPart().getEnvelope().removeNamespaceDeclaration("env");
sm.getSOAPHeader().setPrefix("soap");
sm.getSOAPBody().setPrefix("soap");
