使用Java进行Base64加密

import java.util.Base64;

public class Ba64Encrypt {

public static void main(String[] args){

    String data = "123456789";

    Base64.Encoder encoder = Base64.getEncoder();
    byte[] bytes = encoder.encode(data.getBytes());
    System.out.println("Base64加密：" + new String(bytes));

      }
}
