错误解散JAXB对象

Question

我具有针对XML架构的JAXB对象。XML模式可以具有不同的根元素。在主要项目中运作良好。根据这些生成的对象，我正在尝试编写一些测试用例。

我写了以下代码以获取jaxbcontext

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

我得到了遵循异常

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

但是，我将上下文行更改为

的那一刻

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

我得到以下异常SEVERE: unexpected element (uri:"", local:"book"). Expected elements are (none)，这是可以根据我的早期问题理解的

有人可以在这里帮我吗？我想创建基于软件包名称的上下文。

看起来像从模式中生成的类之一称为Error，并且编译器在com.store.web.ws.v1.model.Error类中选择了java.lang.Error类。尝试放置一个显式

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

在ObjectFactory.java的顶部并进行重新编译，或者未能编辑该代码以使用完全合格的类名称。

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

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