针对通过Eclipse中的JAXB和XSD构建选项生成的xsd文件验证xml

Question

我试图提供一个示例代码来针对xsd文件验证我的xml文件，该文件通过jaxb和Eclipse的xsd构建生成。

我正在尝试做一个示例验证器文件，该文件针对我的xsd文件验证我的xml。 现在，我发现了很多Java代码示例，并且我正在使用其中的一个。 我也收到了很多我面临的问题的答案，但是从某种意义上来说，这些答案建议更新我的xsd或xml文件。 对我来说，我无法执行任何这些操作，因为我是通过jaxb生成xsd文件的，而通过Eclipse生成了xsd的构建选项。

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;
}

下面是我收到异常的错误：src-resolve：无法将名称'SourceAccountIdentifier'解析为一个（n）'类型定义'组件。

另外，我尝试从xsd定义中删除SourceAccountIdentifier，以查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)

请帮助提供错误的解决方案。 谢谢！！

生成的代码在github上为您服务。

我在猜测这是xml或xsd文件的问题-但我不知道事实。

我暂时删除了dtd ，这是到目前为止的内容：

这些工具是trang和xjc ，可以很容易地在Ubuntu Linux上安装。 这是运行从控制台构建的项目的方法：

即使在Eclipse中也可以使用。 请注意，它使用gradle或Gradle Kotlin DSL作为构建文件，Eclipse应该能够处理。 可能您想导入为gradle项目。

您应该只有改变properties.xml的文件为您的系统 ; 源代码应该很好。
