当我使用 JAXB 验证 XML 文件时，您能帮我获取所有错误的列表吗？

现在我已经实现了相同的代码。我已经使用解组 XML 文件实现了代码。

当我当时解组 XML 文件时，如果 XML 文件中存在任何错误，我得到了异常，但它在给出第一个异常后出现了，但我想要该 XML 文件的所有错误的列表。出现第一个错误后，这不应该出现。

Source xsdFileName = new StreamSource(new File("validate6.xsd"));
    Source xmlFileName = new StreamSource(new File("test3.xml"));

    try {
        SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        Schema schema = sf.newSchema(xsdFileName);

        JAXBContext jc = JAXBContext.newInstance(Innovations.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        unmarshaller.setSchema(schema);
        unmarshaller.setEventHandler(new MyValidationEventHandler());
        Innovations innovation = (Innovations) unmarshaller.unmarshal(xmlFileName);

        System.out.println("Total Size :: " + innovation.getInnovationList().size());
        System.out.println(xmlFileName.getSystemId() + " is valid");
    } catch (JAXBException e) {
        e.printStackTrace();
        System.out.println(xmlFileName.getSystemId() + " is NOT valid");
    } catch (SAXParseException e) {
        e.printStackTrace();
        System.out.println(xmlFileName.getSystemId() + " is NOT valid");
    } catch (SAXException e) {
        e.printStackTrace();
        System.out.println(xmlFileName.getSystemId() + " is NOT valid");
    }

验证事件处理程序类

public class MyValidationEventHandler implements ValidationEventHandler {

public boolean handleEvent(ValidationEvent event) {
    System.out.println("\nEVENT");
    switch (event.getSeverity()) {
    case 0:
        System.out.println("SEVERITY:  WARNING");
        break;
    case 1:
        System.out.println("SEVERITY:  ERROR");
        break;
    case 2:
        System.out.println("SEVERITY:  FATAL_ERROR");
        break;
    }
    System.out.println("MESSAGE:  " + event.getMessage());
    System.out.println("LINKED EXCEPTION:  " + event.getLinkedException());
    System.out.println("LOCATOR");
    System.out.println("    LINE NUMBER:  " + event.getLocator().getLineNumber());
    System.out.println("    COLUMN NUMBER:  " + event.getLocator().getColumnNumber());
    System.out.println("    OFFSET:  " + event.getLocator().getOffset());
    System.out.println("    OBJECT:  " + event.getLocator().getObject());
    System.out.println("    NODE:  " + event.getLocator().getNode());
    System.out.println("    URL:  " + event.getLocator().getURL());
    return true;
}

}

输出：

我想自定义验证器会帮助你：

public class MyValidationEventHandler implements ValidationEventHandler{

    public boolean handleEvent(ValidationEvent ve) {            
        if (ve.getSeverity()==ve.FATAL_ERROR ||  
                ve .getSeverity()==ve.ERROR){
            ValidationEventLocator  locator = ve.getLocator();
            //print message from valdation event
            System.out.println("Message is " + ve.getMessage());
            //output line and column number
            System.out.println("Column is " + 
                    locator.getColumnNumber() + 
                    " at line number " + locator.getLineNumber());
        }
        return true;
    }

}

接着

setEventHandler(new MyValidationEventHandler());

好的，所以问题出在这里：

/test3.xml is NOT valid javax.xml.bind.UnmarshalException - with linked exception: [org.xml.sax.SAXParseException; systemId: file:/D:/AHWeb2.0.3/test3.xml; lineNumber: 25; columnNumber: 5; The element type "case_manager1" must be terminated by the matching end-tag "".] at javax.xml.bind.helpers.AbstractUnmarshallerI mpl.createUnmarshalException(Unknown Source) at...

您的 XML 的第 25 行不正确 - 它缺少结束标记。

由于 XML 在语法上不正确，因此这种模式验证机制无法继续传递严重错误。
