java.net.MalformedURLException : no protocol

Question

我正在编写一个类以在 Java 中运行 xjc。我的代码如下:

 URL url = new URL("C:\\Users\\Simran\\Desktop\\books.xsd"); 
 SchemaCompiler sc = XJC.createSchemaCompiler();
 sc.parseSchema(new InputSource(url.toExternalForm()));
 S2JJAXBModel model = sc.bind();
 JCodeModel cm = model.generateCode(null, null);
 cm.build(new FileCodeWriter(new File("C:\\Users\\Simran\\Desktop\\books.xsd")));

但是当我运行它时出现以下错误:

Exception in thread "main" java.net.MalformedURLException: no protocol: books.xsd
    at java.net.URL.<init>(Unknown Source)
    at java.net.URL.<init>(Unknown Source)
    at java.net.URL.<init>(Unknown Source)
    at jaxbTest.Test1.main(Test1.java:22)

有人可以帮忙吗？

尝试将 "file://" 附加到文件路径的开头。但正如 Bozho 所建议的，您在这里不需要 URL。
