java - 根据 Eclipse 中通过 JAXB 和 XSD 构建选项生成的 xsd 文件验证 xml

Question

我正在尝试使用示例代码来根据 xsd 文件验证我的 xml 文件，该文件是通过 Eclipse 的 jaxb 和 xsd 构建生成的。

我正在尝试制作一个示例 validator 文件，该文件根据我的 xsd 文件验证我的 xml。现在，我找到了很多java代码的例子，我正在使用其中之一。另外，我收到了很多关于我面临的问题的答案，但在某种程度上，这些答案建议更新我的 xsd 或 xml 文件。对我来说，我无法执行这些操作，因为我通过 Eclipse 的 jaxb 和 xsd 构建选项生成 xsd 文件。

try {
SchemaFactory factory = 
SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(new File(xsdPath));
Validator validator = schema.newValidator();
validator.validate(new StreamSource(new File(xmlPath)));
} catch (IOException e) {
System.out.println("Exception: "+e.getMessage());
return false;
} catch( SAXException e){
System.out.println("Exception: "+e.getMessage());
return false;
}
return true;
}

以下是我收到的错误异常:src-resolve:无法将名称“SourceAccountIdentifier”解析为“类型定义”组件。

此外，我尝试从 xsd 定义中删除 SourceAccountIdentifier，看看它是否在其他地方失败，在这种情况下，我收到以下错误

Exception: src\main\java\com\citi\cbol\test\MLIspec-1.6.dtd (The system cannot find the file specified)

请帮忙提供一些错误的解决方案。谢谢!!

生成的代码位于 github为你。

我猜测这是 xml 或 xsd 文件的问题 - 但我不知道事实。

我暂时删除了 dtd，这是我目前所拥有的:

即使在 Eclipse 中也应该可以工作。请注意，它使用 gradle 或 Gradle Kotlin DSL 作为构建文件，Eclipse 应该能够处理该文件。也许您想导入为 gradle 项目。

您只需更改 properties.xml 文件 for your system ;源代码应该没问题。
