java web项目，java类中获得WEB-INF路径

 

 

private static String getWebInfPath() {
		URL url = 当前类.class.getProtectionDomain().getCodeSource().getLocation();
		String path = url.toString();
		int index = path.indexOf("WEB-INF");
		if (index == -1) {
			index = path.indexOf("classes");
		}
		if (index == -1) {
			index = path.indexOf("bin");
		}
		path = path.substring(0, index);
		if (path.startsWith("zip")) {// 当class文件在war中时，此时返回zip:D:/...这样的路径
			path = path.substring(4);
		} else if (path.startsWith("file")) {// 当class文件在class文件中时，此时返回file:/D:/...这样的路径
			path = path.substring(6);
		} else if (path.startsWith("jar")) {// 当class文件在jar文件里面时，此时返回jar:file:/D:/...这样的路径
			path = path.substring(10);
		}
		try {
			path = URLDecoder.decode(path, "UTF-8");
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}
		return path;
