我有针对 XML 模式的 jaxb 对象。该 xml 架构可以具有不同的根元素。这在主要项目中运行良好。基于这些生成的对象，我正在尝试编写一些测试用例。

我编写了以下代码来获取 JAXBContext

JAXBContext jaxbContext = JAXBContext.newInstance("com.store.web.ws.v1.model");

我得到以下异常

com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
java.lang.StackTraceElement does not have a no-arg default constructor.
    this problem is related to the following location:
        at java.lang.StackTraceElement
        at public java.lang.StackTraceElement[] java.lang.Throwable.getStackTrace()
        at java.lang.Throwable
        at java.lang.Error
        at public java.lang.Error com.store.web.ws.v1.model.ObjectFactory.createError()
        at com.store.web.ws.v1.model.ObjectFactory

    at javax.xml.bind.JAXBContext.newInstance(JAXBContext.java:244)
    at com.store.web.ws.v1.resource.RequestInfo.main(RequestInfo.java:171)

但是，当我将上下文行更改为

JAXBContext jaxbContext = JAXBContext.newInstance(BookType.class);

SEVERE: unexpected element (uri:"", local:"book"). Expected elements are (none)根据我之前的问题，我得到以下异常是可以理解的

有人可以在这里帮助我吗？我想根据包名称创建一个上下文。

看起来从您的模式生成的类之一被称为Error，并且编译器已经选择了java.lang.Error该类而不是com.store.web.ws.v1.model.Error该类。尝试明确

import com.store.web.ws.v1.model.Error;

在顶部ObjectFactory.java并重新编译它，或者未能编辑代码以使用完全限定的类名。

public com.store.web.ws.v1.Error createError() {
  return new com.store.web.ws.v1.Error();
}

（或更改类名并使用 将其重新映射到正确的元素名@XmlRootElement(name="Error")）
