MalformedURL 读取文件时出现异常

Question

我从 weblogic 8.1 环境中复制了一段代码，然后复制到新环境 weblogic 10.3.4 中。以下代码在我的 8.1 环境中运行。当我使用相同的代码时，它给出了以下异常。

代码

  String xmlPath="e:\\domains\\devdamsdomain\\j2ee\\configurations\\dcd\\dams\\common\\interfaceconfig.xml";
  log.info("xmlpath" + xmlPath);
  SAXBuilder saxBuilder = new SAXBuilder();
  log.info("creating SAXBuilder");
  Document document = saxBuilder.build(xmlPath);

异常如下：

请给我建议。

Answer 1

您使用的方法接受 URL 的字符串表示形式，并且根据 url 格式，e: 不是有效协议（它被视为有效协议，因为它位于第一个冒号之前）

您有多个选项解决这个问题：

• 使用 .build(new File(path)) （最好）
• 添加文件协议 file://e/etc.. （解决眼前的问题）

Answer 2

您可以尝试 file:///e:/domains/...

Answer 3

如前所述，这是因为文件路径格式错误。解决方案是使用类似的路径。

document = builder.parse(new File(<pathtoberead>).toURI().toString());
