JIBX：从maven codegen插件生成的类：没有元素的unmarshaller

Question

我使用Jibx CodeGen maven插件从xsd文件生成java源代码和绑定。 我想在相同的应用程序中维护xsd的几个版本，所以我打算根据XSD的版本生成不同的目标包。

JBix似乎根据xsd文件的名称空间生成java包。

即。对于名称空间http://www.example.jibx.org/generated/v30/types，它会生成包org.jibx.example.generated.v30.types

在maven构建代码生成期间似乎有效并且生成了绑定文件，但在绑定阶段，它表示Verification失败了：

我编写了一个Junit测试，以确保jibx可以为我的绑定对象实例化工厂，并对其进行解组xml文件。

Junit单元测试：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);
    }

foo1.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <foo>
        <generic>
            <type>12345</type>

            <dateFoo>01/01/2015</dateFoo>
        </specific>
    </foo>

当我运行它时，我得到了这个堆栈跟踪：没有元素的unmarshaller＆＃34; generic＆＃34;

ERROR FooTest - Cannot instanciate object for class class org.jibx.example.generated.v30.foo.Foo

Answer 1

马克，

查看JiBX模式库中

的示例

Opentravel schema Library

它与您的问题非常相似许多具有相同命名空间的模式需要绑定到不同的Java包。

另外，我建议您使用较新版本的JiBX，例如1.2.6

干杯！

唐

Answer 2

我终于找到了答案。我在我想要使用的xml中缺少名称空间声明。 它适用于正确形状的如下：

    <?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>
