使用Bouncy Castle库: import org.bouncycastle.util.encoders.Base64; // 编码 String encodedString = new String(Base64.encode("Hello World".getBytes())); // 解码 byte[] decodedBytes = Base64.decode(encodedString); String decodedString = new String(decodedBytes); 复制代码 以上三种方式都可以实...

1 首先第一步我们准备环境，准备编码使用的软件myeclipse2014,以及从网上下载org.bouncycastle.jar。此jar包内提供了进行base64加解密相关操作的实体类。2 然后我们打开myeclipse软件，在导航菜单出点击File，然后选择New，然后选择Java Project。进行创建普通Java项目操作。3 然后在项目名称处填写项目的名称：Base64...
