Question

我从SOAP消息中获取附件并在我的应用程序中使用它们。
我不会从原始消息中删除附件。之后，我尝试使用以下代码将原始的 SOAPMessage包含附件（SwA）转换为String：

ByteArrayOutputStream stream = new ByteArrayOutputStream();
soapMsg.writeTo(stream);
String message = new String(stream.toByteArray(), "utf-8");

抛出以下异常：

com.sun.xml.internal.messaging.saaj.soap.MessageImpl writeTo
SEVERE: SAAJ0540: Error during saving a multipart message
com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: Error during saving a multipart message

有没有人对此有所了解？

也许尝试使用StringBuilder而不是String？使用StringBuilder.append()如下所示适用于我，而我无法获得新实例化（正如您使用的那样）String()。

        // This stringbuilder will hold the initial message we sent to SOA
        StringBuilder soapMsg = new StringBuilder();
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        SOAPMessage message = getSoapMessageFromString(foo);

        // Write the initial message to the byte array output string
        message.writeTo(baos);

        // append the baos data (initial message) to the stringbuilder for
        // processing
        soapMsg.append(baos.toString());

        // Reset the baos for use on the response message
        baos.reset();

SoapMessage.writeTo为带有附件的SOAPMessage抛出无内容异常
