我想解组我从REST调用中收到的这个xml文档:
<ns2:hello xmlns:ns4="http://myspace.org/hello/history/1.0" xmlns:ns3="http://www.hello.com/IAP/im1_1_0" xmlns:ns2="http://www.w3.org/2005/Atom">
<ns3:totalEntries>7</ns3:totalEntries>
<ns2:id>123</ns2:id>
<ns2:title type="text">Users</ns2:title>
<ns2:updated>2017-08-22T07:51:27.270Z</ns2:updated>
<ns2:link href="https://example.com:8080/1/rest/users" rel="self"/>
<ns2:link href="https://example.com:8080/1/rest/users" rel="http://www.example.com/iap/im/user/create"/>
<ns4:complete/>
<ns2:entry>
<ns2:id>urn:uuid:f0fd4040-04da-11e7-8f6a-8e3ecfcb7035</ns2:id>
<ns2:title type="text">Hello</ns2:title>
<ns2:content type="application/vnd.bosch-com.im+xml">
<ns3:user>
<ns3:id>f0fd4040-04da-11e7-8f6a-8e3ecfcb7035</ns3:id>
<ns3:name>name</ns3:name>
<ns3:firstName>Hello</ns3:firstName>
<ns3:lastName>All</ns3:lastName>
</ns3:user>
</ns2:content>
</ns2:entry>
</ns2:hello>
正如您所看到的,XML是嵌套的,为此我使用JAXB进行解组:
try {
JAXBContext jc = JAXBContext.newInstance(Feed.class);
Unmarshaller um = jc.createUnmarshaller();
Feed feed = (Feed) um.unmarshal(new StringReader(userEntity.getBody()));
System.out.println(feed.getEntry().get(0).getContent().getUser().getFirstName());
}
catch (JAXBException e) {
e.printStackTrace();
}
但是,我没有在我的POJO中获取任何数据(它是空的):
@XmlRootElement(namespace="http://www.w3.org/2005/Atom", name="hello")
public class Hello {
private String id;
private String totalEntries;
private String title;
private String updated;
List<Entry> entry;
Complete complete;
}
我的POJO如上所示。我还创建了Entry和Complete POJO类。我该如何解决这个问题?
答案 0 :(得分:0)
XML有3个名称空间:
xmlns:ns4="http://myspace.org/hello/history/1.0"
xmlns:ns3="http://www.hello.com/IAP/im1_1_0"
xmlns:ns2="http://www.w3.org/2005/Atom"
您需要确保每个元素都在正确的命名空间@XmlElement(namespace="xmlns:ns3="http://www.hello.com/IAP/im1_1_0") etc
中,以便能够正确解组
您还可以从添加@XmlType(propOrder = { "totalEntries", ...

您是否尝试过将getter和setter添加到类Hello?
您的示例使用Hello的简化版本。
@XmlRootElement(namespace = "http://www.w3.org/2005/Atom", name = "hello")
public class Hello {
private String id;
private String title;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
和测试类
public class Test {
public static void main(String[] args) {
try {
JAXBContext jc = JAXBContext.newInstance(Feed.class);
Unmarshaller um = jc.createUnmarshaller();
InputStream file = new FileInputStream("path/to/file/feed.xml");
Hello feed = (Hello) um.unmarshal(file);
System.out.println(feed.getId());
System.out.println(feed.getTitle());
} catch (JAXBException | FileNotFoundException e) {
e.printStackTrace();
}
}
}
