public static void main(String[] args) throws UnsupportedEncodingException {
    		// 秘钥
    		String secretKey = "HXJK#2022@(hxjk)";
    
    		String strEncryption = "/te/teLoanDetail/2097";
    		String strDecryption = "am81elBVSjYzMVkxR252RzNEZkNqMG5HNnhuTmRBaGU=";
    
    		// 加密
    		String s1 = Des3Util.encode3Des(secretKey, strEncryption);
    		String encodeToString = java.util.Base64.getUrlEncoder().encodeToString(s1.getBytes());
    		System.out.println("----->s1:" + encodeToString);//am81elBVSjYzMVkxR252RzNEZkNqMG5HNnhuTmRBaGU=
    
    		// 解密
    		String resultEncryption = new String(java.util.Base64.getUrlDecoder().decode(strDecryption), "UTF-8");
    		String s2 = Des3Util.decode3Des(secretKey, resultEncryption);
    		System.out.println("----->s2:" + s2);// /te/teLoanDetail/2097
