读取ar包中所有属性文件值

public class JarEntryTest {
	
	public static void main(String[] args) throws IOException, SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException {
		JarFile jarFile = new JarFile("d:/quartz-1.6.5.jar");
		Method method = URLClassLoader.class.getDeclaredMethod("addURL", new Class[]{URL.class});
		method.setAccessible(true);
		InputStream in = null;
		List<String> lines = null;
		int c = 0;
		URLClassLoader classLoader = (URLClassLoader)ClassLoader.getSystemClassLoader();
		method.invoke(classLoader, new Object[]{new URL("file:/d:/quartz-1.6.5.jar")});
		Enumeration<JarEntry> entrys = jarFile.entries();
		while (entrys.hasMoreElements()) {
			JarEntry entry  = entrys.nextElement(); 
			String name = entry.getName();
			if(name.endsWith(".properties")) {
				try {
					in = classLoader.getResourceAsStream(name);
					lines = IOUtils.readLines(in);
				} catch (Exception e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} finally {
					IOUtils.closeQuietly(in);
				}
				for (String line : lines) {
					System.out.println(name + "              " + line);
				}
			}
			
		}
	}
}

了解这点后，对于读取国际化资源文件有所帮助
这里需要温习一下getdeclaredmethod getmethod之间的区别
