我试图做这样的事情，但它似乎不起作用.谢谢！
I was trying to do something like this, but it doesn't seem to work. Thanks!
Scanner sc1 = new Scanner(new File("src/web/web.html"));
String webStr = sc1.useDelimiter("\Z").next();
Scanner sc2 = new Scanner(new File("src/web/data.js"));
String dataStr = sc2.useDelimiter("\Z").next();
Scanner sc3 = new Scanner(new File("src/web/cytoscape.min.js"));
String cytoStr = sc3.useDelimiter("\Z").next();
Scanner sc4 = new Scanner(new File("src/web/jquery.min.js"));
String jqueryStr = sc4.useDelimiter("\Z").next();
webEngine.loadContent(cytoStr, "text/javascript");
webEngine.loadContent(jqueryStr, "text/javascript");
webEngine.loadContent(dataStr, "text/javascript");
webEngine.loadContent(webStr, "text/html");
推荐答案
我刚刚发现在 HTML 中使用
I just found out that using the <base> tag in the HTML also does the trick:
<html>
<head>
<title>The slash at the end of the href is important!</title>
<base href="file:///absolute/path/to/your/docroot/" />
</head>
<body>
<img src="image.png"/>
</body>
</html>
如果你通过 engine.loadContent(String) 加载上面的代码，那么 image.png 将从 /absolute/path/to/your/加载docroot/image.png.
If you load the above code via engine.loadContent(String) then image.png will be loaded from /absolute/path/to/your/docroot/image.png.
如果您需要加载多个资源，这种方法更容易，因为您只需在一个地方指定绝对路径.
This method is easier if you need to load multiple resources since you only have to specify the absolute path at a single place.
这已经用 Java 8u25 的 WebView 测试过.
This has been tested with WebView of Java 8u25.
