JAXB gives me: java.lang.IllegalArgumentException: is parameter must not be null
提问by SCdF
I am doing this using JAXB to unmarshall some XML into Java objects:
我正在使用 JAXB 将一些 XML 解组为 Java 对象：
My code looks a little like this:
我的代码看起来有点像这样：
InputStream testMsg = getClass().getResourceAsStream("TestDocumentEvent.xml");
Unmarshaller unmarshaller = JAXBContext.newInstance(DocumentEvent.class).createUnmarshaller();
DocumentEvent unmarshalled = (DocumentEvent) unmarshaller.unmarshal(testMsg);
However, when I run this code I get an exception:
但是，当我运行此代码时，出现异常：
java.lang.IllegalArgumentException: is parameter must not be null
What's going on?
这是怎么回事？

This is because the InputStreamyou are passing to the unmarshaller ('is' parameter, geddit) is null, check that the resource name is correct.
这是因为InputStream您传递给解组器（'is' 参数，geddit）为空，请检查资源名称是否正确。
