我有一个客户的答复是 ByteArrayInputStream 我正在缓冲读取并创建一个stringreader来读取pojo表单中的xml。我想解开它，但我得到的名称空间问题，因此jaxbexception。
以下是我得到回复后的代码：

public void post() {
        ...

        ByteArrayInputStream obj = (ByteArrayInputStream) response.getEntity();
        BufferedReader br = new BufferedReader(new InputStreamReader(obj));
        String line = null;
        StringBuffer sb = new StringBuffer();
        try{
            while ((line = br.readLine()) != null){
                System.out.println(line);
                sb.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        JAXBContext jaxbContext = JAXBContext.newInstance(FileTransmissionResponse.class);
        Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

        StringReader reader = new StringReader(sb.toString());
        FileTransmissionResponse transmissionResponse = (FileTransmissionResponse) 
        unmarshaller.unmarshal(reader);

}

这个 StringBuffer 响应是以下字符串格式的xml：

<?xml version="1.0" encoding="UTF-8"?>
<fileTransmissionResponse xmlns="http://abc.xyz.com/schema/auditing/fileResponse-1.1">
   <version>1.0</version>
   <userId>xqas</userId>
   <reNumber>1234</reNumber>
   <reName>1234rfd</reName>
   <status>FAILURE</status>
   <fileName>file.xml</fileName>
   <startTime>2021-04-06T09:16:54.065+10:00</startTime>
   <finishTime>2021-04-06T09:16:54.743+10:00</finishTime>
   <bytesTransferred>15530</bytesTransferred>
   <emailSent>scd@xyz.com</emailSent>
   ....
</fileTransmissionResponse>

在unmarshal调用之后，由于xmlns命名空间，我得到了一个jaxb异常。有什么方法可以避免这种情况？
