guava的base64

    public static void test004() throws Exception {
        String url = "/user/kanpiaoxue/hello";
        String rs = BaseEncoding.base64().encode(url.getBytes());
        String origin = new String(BaseEncoding.base64().decode(rs));
        System.out.println(String.format("url:%s\nbase64:%s\nborigin:%s", url,rs,origin));
    }

输出结果 写道

url:/user/kanpiaoxue/hello
base64:L3VzZXIva2FucGlhb3h1ZS9oZWxsbw==
borigin:/user/kanpiaoxue/hello
