FileInputStream与File的StreamSource问题

Question

如果StreamSource（FileInputStream），但StreamSource（文件）确定

，则会出现SAX错误

嗨，当参数是FileInputStream时遇到了StreamSource问题。 当参数是File时，没关系。

 public int initXSD (String xsdFile) {

        // no error at all if File
  Source schemaFile = new StreamSource(new File(xsdFile));

        // sax error at newSchema() if FileInputStream
  Source schemaFile = new StreamSource( new FileInputStream(new File(xsdFile))); 

  SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);


     Schema schema = factory.newSchema(schemaFile);
  validator = schema.newValidator();
  return 0;
 }

一旦我更改StreamSource行以获取FileInputStream：

Source schemaFile = new StreamSource( new FileInputStream(new File(xsdFile)));

我在newSchema（）时遇到了sax错误：

org.xml.sax.SAXParseException: src-resolve: Cannot resolve the name 's:ComplexObjectType' to a(n) 'type definition' component.

public int initXSD (String xsdFile) {

    // no error at all if File 
    Source schemaFile = new StreamSource(new File(xsdFile));

    // sax error at newSchema() if FileInputStream 
    Source schemaFile = new StreamSource( new FileInputStream(new File(xsdFile))); 

    Schema schema = factory.newSchema(schemaFile); 
    validator = schema.newValidator(); 
    return 0;
}
