将Java从1.8.0_45更新为1.8.0_131后，JAXB unmarshal字段为空

问题描述 投票：0回答：1

我知道这与许多其他帖子几乎相同，例如JAXB doesn't unmarshall after updating java from 1.8.0_77 to 1.8.0_121，但没有一个答案或评论解决了我的问题。

（我还在这里检查了样本https://github.com/KlausGroenbaek/jaxbissue并通读了这个博客http://blog.bdoughan.com/2012/07/jaxb-no-annotations-required.html）

我升级了Java 8，现在使用示例XML文件进行的大量测试都失败了。

unmarshall返回一个所有字段为null的对象。

我不想要一个需要修改package-info或ObjectFactory的解决方案，因为它们会自动重新生成并覆盖所做的任何更改。

我在其他地方听说过Maven选项

<strict>false</strict>

在POM中应该有所帮助，但事实并非如此。

我不确定它是否是相关的差异，但我的架构xsd是在外部项目中定义的。

unmarshaller代码（在Eden Node项目中）：

    private JAXBContext edmsExchangeJaxbContext;

    public EdmsExchangeUnmarshaller() {
        try {
            edmsExchangeJaxbContext = JAXBContext.newInstance("au.com.edenportal.exchange.edms");

...

    public EdmsExchange unmarshallEdmsMessage(MessageBody messageBody) {

        Reader inputReader = null;

        if (messageBody.getBinaryContent() != null) {
            LOG.debug("Reading MessageBody as binary... ");
            inputReader = new InputStreamReader(new ByteArrayInputStream(messageBody.getBinaryContent().getValue()));
        } else if (messageBody.getTextContent() != null) {
            LOG.debug("Reading MessageBody as text... ");
            inputReader = new StringReader(messageBody.getTextContent());
        }

        Object unmarshalledObject = null;
        try {

            Unmarshaller unmarshaller = edmsExchangeJaxbContext.createUnmarshaller();
            unmarshalledObject = unmarshaller.unmarshal(inputReader);
            inputReader.close();
        } catch (JAXBException e) {
            throw new ExchangeUnmarshallingException("Could not unmarshall payload", e);
        } catch (IOException io) {
            throw new ExchangeUnmarshallingException("IO error when parsing", io);
        }

        @SuppressWarnings("unchecked")
        EdmsExchange edmsExchange = ((JAXBElement<EdmsExchange>) unmarshalledObject).getValue();
        return edmsExchange;

    }

原始的XML样本测试文件（在Eden Node项目中）在1.8.0_45中工作，但现在不在1.8.0_131中：

与原始帖子一样，我在使用不同的java版本时也遇到了同样的问题。我添加了以下依赖项并解决了我的问题

    <dependency>
        <groupId>org.jvnet.jaxb2.maven2</groupId>
        <artifactId>maven-jaxb2-plugin</artifactId>
        <version>0.13.3</version>
    </dependency>
