Question

我已经完成了@Perception对我说的关于模式的URI，但现在我有另一个例外。有谁知道这是什么问题？非常感谢。

我从方法Git60Manager.doImportMod1GtFile获取此代码，该代码使用xsd模板解组文件：

String schema = "///META-INF/templates/git60_data_mod1_def.xsd";
isr = new InputStreamReader(GIT60FileMod1.class.getResourceAsStream(schema));
Unmarshaller unmarshaller = new Unmarshaller(isr, main);

这是xsd文件：

<xs:annotation>
<xs:documentation xml:lang="en">
  GIT60 schema Mod 1 (Data)
</xs:documentation>
</xs:annotation>

<xs:include id="git60_mod1_def.xsd" schemaLocation="./git60_mod1_def.xsd" />

<xs:element name="mainData" type="GIT60FileMod1Data" jrb:length="100" />

<xs:complexType name="GIT60FileMod1Data">
    <xs:sequence>
        <xs:element name="git60Tax" type="GIT60FileTaxMod1" minOccurs="1" maxOccurs="unbounded"/>
    </xs:sequence>
</xs:complexType>

在我运行java.net.MalformedURLException之前运行应用程序时这是个例外：

Answer 1

GIT60FileMod1.class.getResourceAsStream(schema)返回null。它正在发生，因为它无法找到该资源。对于这种方法，值得浏览documentation。

如果类是独立运行的，或者它被打包成JAR文件，则会发生不同的事情。具体来说，它开始的根源以及包装方式将会发生变化。

解组文件有问题。第2部分
