java - PowerMock 不能与 JAXB Unmarshal 一起使用

Question

我正在创建一个测试用例，其中我输入 xml 并将其解码以进行处理。我正在尝试使用 PowerMock，但我一直在使用

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.xxxxxxx.org/xxxxx/xx/xx", local:"Element"). Expected elements are <{}NotifRQ>,<{http://www.xxxxxxx.org/xxxxx/xx/xx}NotifRS>,etc

我以这种方式解码它:

JAXBContext jaxbContext = JAXBContext.newInstance(NotifRQ.class);
        Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
        NotifRQ notifRQ= (NotifRQ) unmarshaller.unmarshal(new File("filename"));

Answer 1

我遇到了关于 PowerMock 失败的 JAXB 从测试资源解码 XML 数据的相同问题。

我发现这个解决方案有效:只需在下面添加这一行@RunWith(PowerMockRunner.class):

@PowerMockIgnore({ "javax.xml.*", "org.xml.sax.*" })
