XML deserialization using jackson-dataformat-xml custom root element?

Question

So, I am using Jackson to serialize / deserialize JSON successfully, now I am also trying to use it to serialize / deserialize XML using it jackson-dataformat-xml-2.3.0.jar.

I used

objectmapper.reader(Student.class).withRootName("prefix:student").readValue(jsonString)

to deserialize my JSON (with a root name with a prefix) to a class Studentthat worked successfully.

Now I am trying to deserialize my XML string (with root name with prefix) to Student:

XML:

<prefix:student>
  <name>
    Jack Jones
  </name>
  <id>1</id>
</prefix:student>

My POJO:

    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlType(name = "", propOrder = {
        "name",
        "id",
        ....
    })
    @XmlRootElement(name = "student")
    public class Student
    {

        protected String name;
        BigInteger id;  
..........................
    }

I described this using XmlMapperin the jackson-dataformat-xmlfollowing way:

xmlMapper.reader(Student.class).withRootName("prefix:student").readValue(xmlString)

I get the following exception:

java.io.IOException: com.ctc.wstx.exc.WstxParsingException: Undeclared namespace prefix "prefix"

What do I need to do to deserialize XML with a custom root name?

Answer 1

, XML , prefix: ( XML), Jackson XML .

XML, , " ", .

Answer 2

XmlMapper :

XMLInputFactory input = new WstxInputFactory();
input.setProperty(XMLInputFactory.IS_NAMESPACE_AWARE, Boolean.FALSE);
XmlMapper xmlMapper = new XmlMapper(new XmlFactory(input, new WstxOutputFactory()));

, , @XmlRootElement(name= "student") @XmlRootElement(name= "prefix:student")

:

StaxMan, , , .

, ( 1 9 = > ").

, XML.

, StaxMan , :

<prefix:student xmlns:prefix="http://www.somenamespace.org">
  <name>
    Jack Jones
  </name>
  <id>1</id>
</prefix:student>
