JIBX：从 Maven Codegen 插件生成的类：没有元素的解组器

2024-03-02

我使用 Jibx CodeGen maven 插件从 xsd 文件生成 java 源和绑定。 我想在同一应用程序中维护多个版本的 xsd，因此我计划根据 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。

IE。对于命名空间http://www.example.jibx.org/generated/v30/types它生成包org.jibx.example.generated.v30.types

在 Maven 构建代码生成期间似乎可以工作并生成绑定文件，但在绑定阶段，它表示验证失败：

我编写了一个 Junit 测试，以确保 jibx 可以实例化我的绑定对象的工厂并针对它解组 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>
            <isValid>1</isValid>
        </generic>
        <specific>
            <label>Label example</label>
            <dateFoo>01/01/2015</dateFoo>
        </specific>
    </foo>

当我运行它时，我得到了这个堆栈跟踪：No unmarshaller for element "generic"

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

Marc,

查看 JiBX 模式库中的示例以了解

Opentravel 模式库 http://jibx.org/schema-library/site.html#opentravel.org

这与您的问题非常相似许多具有相同名称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

Cheers!

Don
