更新
我发现了一些可能相关的东西，removing whitespace from the response .但最好的方法是什么？

我正在将 Tomcat 6(使用 Java 6)服务器迁移到 Tomcat 8.5(使用 Java 8u111)。其中一个 jsp 在新服务器上给我带来了问题。它发送 SOAP 请求并处理响应。我从中得到以下错误
Error : com.sun.xml.internal.messaging.saaj.soap.impl.TextImpl cannot be cast to javax.xml.soap.SOAPBodyElement
执行第245行时
SOAPBodyElement sbeResponseRoot = (SOAPBodyElement) iterRoot.next();
这是它试图处理的 SOAP 响应。

关于为什么会发生这种情况有什么想法吗？
最佳答案
好吧，如果其他人遇到了这个问题，这就是我发现的以及我如何修复它的。 body 元素中的空格，如换行符、回车符和制表符搞砸了子元素的解析。为了去除它们，我替换了以下行:
SOAPMessage smResponse = scTunnel.call(smRequest, urlWebService);
使用此代码片段:
SOAPMessage smResponse2 = scTunnel.call(smRequest, urlWebService);
// strip off the newlines and CR's and tabs.
java.io.ByteArrayOutputStream baosHolder = new java.io.ByteArrayOutputStream();
smResponse2.writeTo(baosHolder);
String strSOAPMsg = baosHolder.toString().replaceAll("\n+","").replaceAll("\r+","").replaceAll("\t+","");
SOAPMessage smResponse = mfFactory.createMessage(new MimeHeaders(), new java.io.ByteArrayInputStream(strSOAPMsg.getBytes(java.nio.charset.Charset.forName("UTF-8"))));
通过 java.io.ByteArrayOutputStream 对象将 javax.xml.soap.SOAPMessage 转换为字符串，替换了有问题的字符，并将其包装回一个新的 SOAPMessage 对象，它没有空格并且可以正常解析。
这变成了这样的回应:
<?xml version="1.0" encoding="UTF-8" ?>
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<SOAP-ENV:Body>
<ns1:WS_TestResponse xmlns:ns1="LLX_Service">
<outResultCode xsi:type="xsd:int">-1</outResultCode>
<outResultMsg xsi:type="xsd:string">Invalid ID Value, record not found</outResultMsg>
<outResultData xsi:type="xsd:string">IsTermed=No</outResultData>
</ns1:WS_TestResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
为此:
<?xml version="1.0" encoding="UTF-8" ?><SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><SOAP-ENV:Body><ns1:WS_TestResponse xmlns:ns1="LLX_Service"><outResultCode xsi:type="xsd:int">-1</outResultCode><outResultMsg xsi:type="xsd:string">Invalid ID Value, record not found</outResultMsg><outResultData xsi:type="xsd:string">IsTermed=No</outResultData></ns1:WS_TestResponse></SOAP-ENV:Body></SOAP-ENV:Envelope>
如果有更简单的方法，我很想听听。
关于java - 为什么不能将 com.sun.xml.internal.messaging.saaj.soap.impl.TextImpl 转换为 javax.xml.soap.SOAPBodyElement，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41355036/
