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xsd的多个版本，因此我计划根据XSD的版本生成不同的目标包。
JBix似乎基于xsd文件的名称空间生成Java包。
即。对于命名空间，http://www.example.jibx.org/generated/v30/types它生成包org.jibx.example.generated.v30.types
http://www.example.jibx.org/generated/v30/types
org.jibx.example.generated.v30.types
在maven构建代码生成期间，似乎可以正常工作，并且生成了绑定文件，但是在绑定阶段，它表示Verification失败：

这是生成的绑定（binding-v30.xml）

我编写了一个Junit测试，以确保jibx可以实例化绑定对象的工厂，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>
我在运行它时得到了这个堆栈跟踪：元素“通用”没有解组器

我终于找到了答案。我想使用的xml中缺少namepace声明。它可以与以下形状正确的形状一起使用：
