使用 jaxb 异常解组 xml 文件

Question

我正在尝试解组一个 xml 文件，但我遇到了一个绑定异常，我刚开始使用 xml 和带有 java 的模式，但从我的角度来看可以看出，当它试图将 xml 绑定到我正在使用的 xsd 模式时，它看起来像是命名空间的问题。

我一直在努力解决这个问题，但似乎找不到问题所在。提前致谢。

这是我得到的异常：

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

这是 xml:

上的名称空间声明

<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 xsd 上的命名空间声明：

<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>

这是我尝试解组文件的方法：

    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

您的 XML 在默认命名空间中：

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

我怀疑您可能需要

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

或

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

使用 jaxb 异常解组 xml 文件

java

xsd
