在Swing应用程序中访问.jar下的文件? [英] Accessing files under .jar in a swing application?

问题描述

请参阅我的上一个问题，我想问一下如何读取其他文件 文件夹放入类似的.jar.

Referring to my previous question, I want to ask that how can I read a file in different folder into the similar .jar.

该问题提供了文件夹层次结构和详细信息. 我的主要问题是一行代码:

The folder hierarchy and details are provided with that question. My main problem is with a line of code:

JTextPane textPane = ... //general initialization
textPane.setPage("path/file.html");

问题是我必须将那个file.html保留在我的.jar中.

The problem is I have to keep that file.html in my .jar.

此外，我想了解有关此主题的建议.

Moreover I would like to know suggestions on this topic.

推荐答案

要在JAR中加载资源，可以使用Class.getResource().从不在JAR中的普通文件夹结构进行加载时，此方法同样有效:

For loading resources in a JAR, you can use Class.getResource(). This works equally well when loading from an ordinary folder structure not in a JAR:

textPane.setPage(ThisClass.class.getResource("relative/path/to/file.html"));

此处的路径来自ThisClass.class所在的文件夹.通常最好显式地命名该类而不是使用this.getClass()，如果调用此方法，则最终可能会在不同的位置(并且是非预期的)一个子类.

The path here is from whatever folder ThisClass.class is in. It is generally better to explicitly name the class rather than using this.getClass(), which may end up looking in a different (and unintended) location if this method is called for a subclass.
