将XML解组为嵌套标签的对象

Question

I've got some generated classes from a 3rd party provider for their API - specifically Companies House ( http://xmlgw.companieshouse.gov.uk/ ) 我从第三方供应商那里获得了一些针对其API的生成的类-特别是Companies House（ http://xmlgw.companieshouse.gov.uk/ ）

I'm having trouble unmarshalling the parts of the response from the API. 我在解组来自API的响应部分时遇到了麻烦。 I can cast the object to a GovTalkMessage object, which contains a Body tag - but the underlying object I get back after unsmarshalling is a ElementNSImpl object instead of the expected pojo. 我可以将对象转换为GovTalkMessage对象，该对象包含一个Body标记-但解组后返回的基础对象是ElementNSImpl对象，而不是预期的pojo。

Example 例

I create a request like this one: http://xmlgw.companieshouse.gov.uk/examples/companydetails_req.xml 我创建了这样的请求： http : //xmlgw.companieshouse.gov.uk/examples/companydetails_req.xml

And get a response like this one: http://xmlgw.companieshouse.gov.uk/examples/companydetails_reply.xml 并得到这样的响应： http : //xmlgw.companieshouse.gov.uk/examples/companydetails_reply.xml

You can see in the reply that there is: 您可以在回复中看到：

<Body>
<CompanyDetails xmlns="http://xmlgw.companieshouse.gov.uk/v1-0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlgw.companieshouse.gov.uk/v1-0/schema/CompanyDetails-v2-1.xsd">
    ...
</Body>

So the contents of the Body (which is a List<Object> in the generated GovTalkMessage pojo) should have a CompanyDetails object in the first element of the list. 因此， GovTalkMessage的内容（在生成的GovTalkMessage pojo中为List<Object> ）应该在列表的第一个元素中具有CompanyDetails对象。 I instead have ElementNSImpl . 相反，我有ElementNSImpl 。

Here's the marshalling code, which works fine - can send it to the API endpoint and comes back with an xml response like the example above: 这是编组代码，可以很好地工作-可以将其发送到API端点并返回xml响应，如上面的示例：

JAXBContext context = JAXBContext.newInstance(GovTalkMessage.class, CompanyDetailsRequest.class, CompanyDetails.class);
Marshaller marshaller = context.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);

InputStream in = Request.Post ... //omitted - send to server, get response

Unmarshaller unmarshaller = context.createUnmarshaller();
GovTalkMessage reply = (GovTalkMessage)unmarshaller.unmarshal(in); //ok
Object object = reply.getBody().getAny().get(0); 
//object is ElementNSImpl - should be CompanyDetails

Am I doing something wrong in the unmarshal? 我在海警中做错什么了吗？

Thanks in advance 提前致谢

UPDATE 更新

If I modify the package-info.java to have 如果我将package-info.java修改为

namespace = "http://xmlgw.companieshouse.gov.uk/v1-0/schema"

instead of 代替

namespace = "http://www.govtalk.gov.uk/CM/envelope"

then the unmarshal works. 然后元帅工作。 But I can't get both marshal into GovTalkMessage and unmarshal into CompanyAppointments to work, even if I specify it directy: 但是，即使我直接指定它，我也无法将其 GovTalkMessage送到GovTalkMessage并将其GovTalkMessage送到CompanyAppointments中。

JAXBContext payloadContext = JAXBContext.newInstance(CompanyAppointments.class);
Unmarshaller unmarshaller = payloadContext.createUnmarshaller();
unmarshaller.unmarshal((Node)message.getBody().getAny().get(0), CompanyAppointments.class).getValue();

This just gives me a CompanyAppointments with fields full of nulls. 这只是给我一个CompanyAppointments其中的字段充满了空值。

Answer 1

It seems namespace used for generating binding classes and one received in response are conflicted. 似乎用于生成绑定类的名称空间与响应中收到的名称空间发生冲突。

binding class and XML response will be required to point out error here :). 绑定类和XML响应将需要在此处指出错误：）。

I'll suggest you to use package name in place of classes for creating JAXBContext. 我建议您使用包名称代替用于创建JAXBContext的类。

final JAXBContext context = JAXBContext.newInstance("com.something"...);
