以下代码在Java 7中运行良好

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;

String xmlString = '<xml ..... ';

StringReader reader = new StringReader(xmlString);

JAXBContext jc = JAXBContext.newInstance(MyClass.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
MyClass myClass = (MyClass) unmarshaller.unmarshal(reader);
....

现在我们不得不升级到Java 8,现在我在执行代码时遇到了这个异常:

Sep 03, 2014 1:42:47 PM com.sun.xml.internal.bind.v2.util.XmlFactory createParserFactory
SCHWERWIEGEND: null
org.xml.sax.SAXNotRecognizedException: Feature: http://javax.xml.XMLConstants/feature/secure-processing
    at org.apache.xerces.jaxp.SAXParserFactoryImpl.setFeature(SAXParserFactoryImpl.java:100)
    at com.sun.xml.internal.bind.v2.util.XmlFactory.createParserFactory(XmlFactory.java:114)
    at com.sun.xml.internal.bind.v2.runtime.unmarshaller.UnmarshallerImpl.getXMLReader(UnmarshallerImpl.java:139)
    at javax.xml.bind.helpers.AbstractUnmarshallerImpl.unmarshal(AbstractUnmarshallerImpl.java:157)
    at javax.xml.bind.helpers.AbstractUnmarshallerImpl.unmarshal(AbstractUnmarshallerImpl.java:214)

我知道,有一个问题,针对类似的问题,但退一步Java 7的是不是一个解决方案给我.

我试图添加以下maven依赖项

<dependency>
    <groupId>javax.xml</groupId>
    <artifactId>jaxp-api</artifactId>
    <version>1.4</version>
</dependency>

但这没有改变结果,所以我删除了它(感谢@BlaiseDoughan的信息,这包含在Java 6中)

欢迎任何提示,非常感谢.

在尝试解组XML数据的输入流时,我遇到了这个异常.这显然是Xerces库的一个问题,但我很难找到解决方案.我在带有Java 8的Glassfish服务器上运行带有EclipseLink的Java EE程序.我的REST服务中出现这种错误,它将XML输入流作为参数.我得到的错误是:

Caused by: java.lang.IllegalStateException: org.xml.sax.SAXNotRecognizedException: unrecognized feature http://javax.xml.XMLConstants/feature/secure-processing
at com.sun.xml.bind.v2.util.XmlFactory.createParserFactory(XmlFactory.java:135)
at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.getXMLReader(UnmarshallerImpl.java:154)
at javax.xml.bind.helpers.AbstractUnmarshallerImpl.unmarshal(AbstractUnmarshallerImpl.java:172)
at javax.xml.bind.helpers.AbstractUnmarshallerImpl.unmarshal(AbstractUnmarshallerImpl.java:219)

我已经看到这里发布的其他问题建议升级我正在使用的Xerces库,并让它成为最重要的依赖,所以Maven抓住了那个而不是其他一些库,但它还没有为我做好.我的POM文件的相关部分是:
