问题描述
我正在尝试通过代码动态加载MySQL jar,但是我不确定Windows路径名的格式.我下面使用的是正确的,用于从thumbdrive加载.jar吗?
I am trying to load a MySQL jar dynamically in code but I am unsure about the format of the Windows path name. Is what I am using below correct, for loading a .jar from a thumbdrive?
URL u = new URL("jar:file:G:/mysql-connector-java-5.1.15.jar!/"); URLClassLoader ucl = new URLClassLoader(new URL[] { u });现在,这与您在Java教程中看到的传统路径不同:
Now, this is not the same as the traditional path that you see in Java tutorials:
URL url = new URL("file:/g:/mysql-connector-java-5.1.15.jar");对于这个问题,我正在寻求澄清;我想我只是对"jar:file:"和!"感到困惑.最后.
For the answer, I am looking for clarification; I guess I am just confused by the "jar:file:" thing and also the "!" at the end.
推荐答案在File对象上使用toURI()方法应该可以解决问题:
Using toURI() method on the File object should do the trick:
final URL u = new File("g:/something.jar").toURI().toURL(); URLClassLoader ucl = new URLClassLoader(new URL[] { u });更多推荐
