请告知此JAXB Unmarshall代码可能存在的问题 这是我尝试解组下面提供的XML时收到的错误消息：

java.lang.RuntimeException：意外元素（uri：“”，local：“code”）。预期元素为＆lt; {} section＆gt;

使用JDK 1.7和Eclipse IDE，使用基于XSD的JaxB解析Borrower类。 

public class UnmarshallApplication {

public static void main(String[] args) {



    try {

    JAXBContext jaxbContext  = JAXBContext.newInstance(Borrower.class);
    Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();

    jaxbUnmarshaller.setEventHandler(new ValidationEventHandler() {
                public boolean handleEvent(ValidationEvent event ) {
                    throw new RuntimeException(event.getMessage(),event.getLinkedException());
                                                                   }
        });


    StringReader xmlCCR = new StringReader(returnValue2());
    JAXBElement<Borrower> root = jaxbUnmarshaller.unmarshal(new StreamSource(xmlCCR), Borrower.class);
    Borrower productListResponse = root.getValue();



    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}

答案 0 :(得分：3)

问题是xsd（因此生成的POJO）和xml不匹配。

例如，正如您在Borrower类中看到的那样，名称和代码都使用@XmlAttribute注释，但您的xml没有将它们作为属性而是作为元素。

更具体地说，你的xml看起来像这样：

<borrower>
   <code>7777777777</code>
   <name>FirstName Surname LastName</name>
   <section>
    ...
</borrower>

但是POJO的构建是为了期待这样的事情（仅关注代码和名称）：

<borrower code="someCode" name="someName">
   <section>
    ...
</borrower>

继续有更多类似的问题。所以我们必须修复你的xsd。它在你的控制之下吗？

如果您将xsd更改为下面的xsd，您将能够解组。
