Java 从SOAP xml解组，getSOAPBody（）方法返回Null

在解组Soap响应时，getSOAPBody返回null。 我尝试过使用XMLStreamReader，它在本例中起作用。但我想知道一种通过ByteArrayInputStream实现的方法。 正确的修复方法是什么。我在下面附上POJOmand package-info.java文件

另外，如果我将“xsi:type=“xsd:string”改为“xsi:type=“string”，它似乎可以工作。我应该如何使我的bean类有效

问题似乎是某种解析错误（getSOAPBody（）似乎没有正确处理名称空间解析）

解决这个问题的“最简单”的方法是自己从SOAP消息中检索原始XML，然而在典型的Java方式中，这个解决方案是复杂和官僚的

您可能需要修改下面的示例代码：

//https://docs.oracle.com/javase/7/docs/api/javax/xml/soap/SOAPPart.html
javax.xml.soap.SOAPPart GSP = SomeSOAPMessage.getSOAPPart();

//https://static.javadoc.io/com.sun.xml.messaging.saaj/saaj-impl/1.4.0/com/sun/xml/messaging/saaj/util/JAXMStreamSource.html
com.sun.xml.messaging.saaj.util.JAXMStreamSource GC = GSP.getContent();

//https://static.javadoc.io/com.sun.xml.messaging.saaj/saaj-impl/1.4.0/com/sun/xml/messaging/saaj/util/ByteInputStream.html
com.sun.xml.messaging.saaj.util.ByteInputStream BIS = GC.getInputStream();

byte[] ByteArray = BIS.getBytes();

java.lang.String Data = new java.lang.String(ByteArray, "UTF-8");

基本上，SOAPPart从消息中获取SOAPPart的内容，它是一个JAXMStreamSource

然后从JAXMStreamSource，它可以有一个“Reader”或“InputStream”（在我的例子中，我发现它有一个“InputStream”）。InputStream可能由应用程序类型决定（在我的例子中是xop+xml，它是“二进制”xml），但是在测试中我发现它是ByteInputStream类型，它是ByteArrayInputStream的扩展类

最后，可以将ByteArray转换为字符串。这个字符串将包含整个XML（包括XML版本头），然后您可以使用希望使用的任何首选XML处理程序类对其进行解析

（包括全名解析和注释参考，以帮助理解其工作原理。）
