JAVA判断32位还是64位，调用不同的DLL（转）

  Properties props = System.getProperties();
  String bits=String.valueOf(props.get("sun.arch.data.model"));  

  String path = IMyNative.class.getResource("/").getPath() + "dll"+bits;
  System.out.println(path);
  // path=path.substring(1,path.length()).replace("/", "\\");
  File file = new File(path + "/MyNative.dll");
  System.out.println(path);
  System.load(path + "/MyNative.dll");
  NativeLibrary.addSearchPath("MyNative.dll", path);
