java - JIBX: Clases generadas a partir del plugin magen codegen: No unmarshaller for element

maven xsd

Question

Utilizo Jibx CodeGen maven Plugin para generar fuentes java y enlaces desde archivos xsd. Quiero mantener varias versiones de xsd en las mismas aplicaciones, así que planeo generar un paquete de destino diferente dependiendo de la versión del XSD.

JBix parece generar un paquete java basado en los espacios de nombres de los archivos xsd.

es decir. para el espacio de nombres http://www.example.jibx.org/generated/v30/types genera el paquete org.jibx.example.generated.v30.types

Durante la generación de código de compilación maven parece funcionar y se generan archivos de enlace, pero durante la fase de enlace, dice que la verificación fue un error:

Escribí una prueba de Junit para asegurarme de que jibx puede instanciar la fábrica para mis objetos enlazados y deshacer un archivo xml contra ella.

Prueba de la unidad de Junit: FooTest.java

@Test
public void testFoo1()
{  
    IBindingFactory foo30Factory = null;
    try
    {
        foo30Factory = BindingDirectory.getFactory("binding_v30", Foo.class);
    }
    catch (JiBXException e)
    {
        String l_msg = "Cannot create factory ";
        LOGGER.error(l_msg, e);
        Assert.fail(l_msg + e.getMessage());
    }

    IUnmarshallingContext unmarshmallingContext = null;
    try
    {
        unmarshmallingContext = foo30Factory.createUnmarshallingContext();
    }
    catch (JiBXException e)
    {
        String l_msg = "Cannot create unmarshmalling context ";
        LOGGER.error(l_msg, e);
        Assert.fail(l_msg + e.getMessage());
    }

    String l_xmlFileToTest = "/xml/foo1.xml";
    LOGGER.info("Loading file : " + l_xmlFileToTest);
    InputStream in = this.getClass().getResourceAsStream(l_xmlFileToTest);
    BufferedReader buffer = new BufferedReader(new InputStreamReader(in));
    Foo l_fooObtained = null;
    try
    {
        l_fooObtained = (Foo) unmarshmallingContext.unmarshalDocument(buffer);
    }
    catch (JiBXException e)
    {
        String l_msg = "Cannot instanciate object for class " + Foo.class;
        LOGGER.error(l_msg, e);
        Assert.fail(l_msg + e.getMessage());
    }

    Assert.assertNotNull("l_coeaObtenu ne doit pas etre null", l_fooObtained);
    }

Obtuve esta stacktrace cuando lo ejecuto: sin unmarshaller para el elemento "genérico"

Answer 1

Bagazo,

Eche un vistazo al ejemplo en la biblioteca de esquemas JiBX para

Biblioteca de esquema de Opentravel

Es muy similar a su problema Muchos esquemas con el mismo espacio de nombres deben estar vinculados a diferentes paquetes de Java.

Además, le sugiero que use una versión más nueva de JiBX, como 1.2.6

¡Aclamaciones!

Answer 2

Finalmente encontré la respuesta. Me faltaba declaración de nombre de usuario en el xml que quería consumir. Funciona con una forma correcta como la siguiente:

    <?xml version="1.0" encoding="UTF-8" ?>
        <foo:foo xmlns:foo="http://www.example.jibx.org/generated/v30/foo"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.example.jibx.org/generated/v30/foo foo-3.0.xsd">
            <generic>
                <type>12345</type>
                <isValid>1</isValid>
            </generic>
            <specific>
                <label>Label example</label>
                <dateFoo>01/01/2015</dateFoo>
            </specific>
        </foo:foo>
