异常unmarshalling xml文件使用jaxb

Question

我想解开一个xml文件，但我得到一个绑定异常，我是新来使用XML和模式与Java，但从我可以告诉，它看起来像一个问题当它尝试将XML绑定到我正在使用的xsd模式时使用命名空间。

我一直在努力工作，我似乎无法找到问题。提前致谢。

这是例外即时得到：

javax.xml.bind.UnmarshalException: unexpected element (URI:"", local:"programacioAula"). Expected elements are <{http://www.xtec.cat/ProgramacioAula}programacioAula> 

这是对XML命名空间声明：

<programacioAula 
    xmlns:tns="http://www.xtec.cat/ProgramacioAula" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://www.xtec.cat/ProgramacioAula ProgramacioAula.xsd "> 

这是对XSD的命名空间声明：

<schema 
    xmlns="http://www.w3.org/2001/XMLSchema" 
    targetNamespace="http://www.xtec.cat/ProgramacioAula" 
    xmlns:tns="http://www.xtec.cat/ProgramacioAula" 
    elementFormDefault="unqualified" 

    attributeFormDefault="unqualified"> 

    <element name="programacioAula" type="tns:ProgramacioAula"></element> 

这是带有XML注释的pojo：

} 

这是我试图来解读该文件的方法：

public static ProgramacioAula readXML(File file) { 
     ProgramacioAula programacioAula = null; 
     try { 
      JAXBContext jaxbContext = JAXBContext.newInstance(dani.java.model.ObjectFactory.class); 
      Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller(); 
      programacioAula = (ProgramacioAula) jaxbUnmarshaller.unmarshal(file); 

     } catch (JAXBException e) { 
      e.printStackTrace(); 
     } 
     return programacioAula; 
    } 

Answer 1

你的XML是默认的命名空间：

<programacioAula 
    xmlns:tns="http://www.xtec.cat/ProgramacioAula" 

我怀疑你可能需要或者

<tns:programacioAula 
    xmlns:tns="http://www.xtec.cat/ProgramacioAula" 

或

<programacioAula 
    xmlns="http://www.xtec.cat/ProgramacioAula"
