基于XSD文件的JAXB Java代码生成

Question

I'm having a problem generating java source code based on XSD file.

Please notice that the XSD file was generated based on XML example.

XML Example

<resposta_importacao>
  <RetornoEnvio xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <num_apolice xmlns="compuletra">202476600001</num_apolice>
    <cod_retorno xmlns="compuletra">651</cod_retorno>
    <mensagem xmlns="compuletra">Erro de layout de dadosobrigat&#195;&#179;rios: cod_cobertura</mensagem>
    <id_validacao xmlns="compuletra">0</id_validacao>
  </RetornoEnvio>
  <RetornoEnvio xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <num_apolice xmlns="compuletra">202476600002</num_apolice>
    <cod_retorno xmlns="compuletra">651</cod_retorno>
    <mensagem xmlns="compuletra">Erro de layout de dados obrigat&#195;&#179;rios: cod_cobertura</mensagem>
    <id_validacao xmlns="compuletra">0</id_validacao>
  </RetornoEnvio>

Generated XSD

<xsd:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:complexType name="RetornoEnvio">
        <xsd:sequence>
            <xsd:element name="num_apolice" type="xsd:integer" xmlns="compuletra" />
            <xsd:element name="cod_retorno" type="xsd:int" xmlns="compuletra" />
            <xsd:element name="mensagem" type="xsd:string" xmlns="compuletra" />
            <xsd:element name="id_validacao" type="xsd:int" xmlns="compuletra" />
        </xsd:sequence>
    </xsd:complexType>

    <xsd:element name="resposta_importacao">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element maxOccurs="unbounded" type="RetornoEnvio" name="RetornoEnvio" />
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>
</xsd:schema>

Generated Java Class

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "RetornoEnvio", propOrder = {
    "numApolice",
    "codRetorno",
    "mensagem",
    "idValidacao"
})
public class RetornoEnvio {

    @XmlElement(name = "num_apolice", required = true)
    protected BigInteger numApolice;
    @XmlElement(name = "cod_retorno")
    protected int codRetorno;
    @XmlElement(required = true)
    protected String mensagem;
    @XmlElement(name = "id_validacao")
    protected int idValidacao;

The problem here is that the XML has the

xmlns="compuletra"

But the java class don't.

I know I can just insert the namespace attribute to the XmlElement annotation but it would be nicer if the code generation could insert it for me.

Thank you

Answer 1

The xmlns attribute in the element defintion in the XML Schema has nothing to do with the namespace qualification of the element. This is why JAXB isn't doing anything with it.

<xsd:element name="cod_retorno" type="xsd:int" xmlns="compuletra" />

Answer 2

Well, just to answer mine own question, so that it does not go unanswered..

I could achieve this namespace difference with the most obvious solution, after thinking of it a little more. Basically using two XSD files with two different namespaces and importing them in a third XSD file.

It all worked as expected.

Thank you,
