java - 资源到url java

Question

所以你肯定知道《我的世界》这款游戏。您可以通过 forge 添加模组。有一个我非常想要的模组，但在启动时它给了我一个错误:

Property exception component:'simpleNGramModel' property:'location' - Bad URL C:\Users\Samuel\Desktop\MultiMC\instances\gfwg\minecraft\config\spells.lmunknown protocol: c

虽然我绝对想要这个模组，而且我认为开发人员已经完成了我想要的项目，并在发现女巫功能后反编译了模组，导致我的世界崩溃，但我真的不知道出了什么问题(我不是一个大java开发人员):

edu/cmu/sphinx/util/props/ConfigurationManagerUtils.class

public static URL getResource(String name, PropertySheet ps)
    throws PropertyException
  {
    String location = ps.getString(name);
    if (location == null) {
      throw new InternalConfigurationException(ps.getInstanceName(), name, "Required resource property '" + name + "' not set");
    }
    try
    {
      URL url = resourceToURL(location);
      if (url == null) {
        throw new InternalConfigurationException(ps.getInstanceName(), name, "Can't locate " + location);
      }
      return url;
    }
    catch (MalformedURLException e)
    {
      throw new InternalConfigurationException(e, ps.getInstanceName(), name, "Bad URL " + location + e.getMessage());
    }
  }

  static final Pattern jarPattern = Pattern.compile("resource:(.*)", 2);

  public static URL resourceToURL(String location)
    throws MalformedURLException
  {
    Matcher jarMatcher = jarPattern.matcher(location);
    if (jarMatcher.matches())
    {
      String resourceName = jarMatcher.group(1);
      return ConfigurationManagerUtils.class.getResource(resourceName);
    }
    if (location.indexOf(':') == -1) {
      location = "file:" + location;
    }
    return new URL(location);
  }

寻求帮助如果我将我的世界移动到另一个磁盘(I://)，我会收到此错误

Property exception component:'simpleNGramModel' property:'location' - Bad URL I:\MultiMC\instances\gfwg\minecraft\config\spells.lmunknown protocol: i

PS:我是法国人，抱歉犯了错误

Answer 1

if (location.indexOf(':') == -1) {
  location = "file:" + location;
}

将其更改为

if (location.indexOf(':') != -1) {
  location = "file:///" + location.replace('\\', '/');
}

如果也失败了，替代解决方案可能是

if (location.indexOf(':') != -1) {
  File f = new File(location);
  return f.toURI().toURL();
}

java.io.File 中也有一个 toURL 方法，但它已被弃用，我避免使用已弃用的方法。
