如何解决JIBX:从Maven Codegen插件生成的类:元素没有解组器
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:
<?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>
解决方法
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
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
