Java-通过相对路径加载dll，并将其隐藏在jar中

我不相信您可以直接从JAR加载DLL。您必须采取将DLL从JAR中复制出来的中间步骤。下面的代码应该这样做：

public static void loadJarDll(String name) throws IOException {    InputStream in = MyClass.class.getResourceAsStream(name);    byte[] buffer = new byte[1024];    int read = -1;    File temp = File.createTempFile(name, "");    FileOutputStream fos = new FileOutputStream(temp);    while((read = in.read(buffer)) != -1) {        fos.write(buffer, 0, read);    }    fos.close();    in.close();    System.load(temp.getAbsolutePath());}
