无法将名称解析为 (n) 'type definition' 组件

Question

我不知道还能做什么：

Caused by: org.xml.sax.SAXParseException; lineNumber: 22; columnNumber: 74; src-resolve: Cannot resolve the name 'head:BusinessApplicationHeader1' to a(n) 'type definition' component.

代码：

  private val schemaLang: String    = javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI
  private val xsdFileSource: BufferedSource = Source.fromResource("main.xsd") 
  private val xsdStream                 = new javax.xml.transform.stream.StreamSource(xsdFileSource.reader())
  private val schema: Schema            = javax.xml.validation.SchemaFactory.newInstance(schemaLang).newSchema(xsdStream)
  private val factory: SAXParserFactory = javax.xml.parsers.SAXParserFactory.newInstance()

  factory.setNamespaceAware(true)
  factory.setValidating(true)
  factory.setFeature("http://apache.org/xml/features/honour-all-schemaLocations", true)
  factory.setSchema(schema)

  private val validatingParser: SAXParser = factory.newSAXParser()

Answer 1

找到解决方案：

如果

 A.xsd imports B.xsd which imports C.xsd

那么显然我们必须以相反的顺序加载模式

javax.xml.validation.SchemaFactory.newInstance(schemaLang).newSchema(Array(C.xsd, B.xsd, A.xsd))

此外，这会停止使用包含（相对于导入）

所以解决方案是加载 xsd 不是作为流而是作为 URL

private val schema: Schema = javax.xml.validation.SchemaFactory .newInstance(javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI) .newSchema( this.getClass.getClassLoader.getResource("main.xsd") )
