在IntelliJ IDEA中,有时使用BASE64Decoder和BASE64Encoder类会遇到报错。这些错误通常是由于缺少相关库或API不兼容引起的。以下是一些可能的原因和相应的解决方案: 缺失Java库:确保你的项目依赖中包含了java.util.Base64所需的库。对于Java 8及更高版本,这个库是标准库的一部分,无需额外添加。对于旧版本的Java,你可...
import java.util.Base64; public class Main { public static void main(String[] args) { byte[] data = "Hello, World!".getBytes(); String encodedData = Base64.getEncoder().encodeToString(data); System.out.println("Base64 encoded string: " + encodedData); } } 复制代码 Base64Decoder: B...
BASE64Decoder decoder = new BASE64Decoder(); byte[] bytes = decoder.decodeBuffer(imagestr); 替换成如下方法即可 import java.util.Base64.Encoder; import java.util.Base64.Decoder; //加解密的包 Encoder encoder = Base64.getEncoder(); String result = encoder.encodeToString(byteArray); Decoder de...

解决Eclipse和MyEclipse中找不到BASE64Encoder Base64的加密解密都是使用sun.misc包下的BASE64Encoder及BASE64Decoder的sun.misc.BASE64Encoder/BASE64Decoder类。这个类是sun公司的内部方法,并没有在java api中公开过,不属于JDK标准库范畴,但在JDK中包含了该类,可以直接使用。但是在Eclipse和MyEclipse中直接使用,却...
This package has both pure PHP andGMPbased encoders. By default encoder and decoder will use GMP functions if the extension is installed. If GMP is not available pure PHP encoder will be used instead. $base32=newTuupola\Base32;$encoded=$base32->encode(random_bytes(128));$decoded=$base32...
By default encoder and decoder will use GMP functions if the extension is installed. If GMP is not available pure PHP encoder will be used instead. $base85 = new Tuupola\Base85; $encoded = $base85->encode(random_bytes(128)); $decoded = $base85->decode($encoded); If you are encoding...
BASE64Decoder BASE64Encoder jar包问题 操作 对项目右击--->build path--->configure build path---> 选中默认jre OK,操作完毕, import sun.misc.BASE64Decoder; import sun.misc.BASE64Encoder; 就可以导入对应的jar包了。

1、第⼀种替代类：jdk1.8的java.util.Base64类 System.out.println(===jdk1.8:java.util.Base64===); //java8 使⽤ Base64.Encoder encoder1 = Base64.getEncoder(); Base64.Decoder decoder1 = Base64.getDecoder(); //编码 String text2 = 字符串、Hell...
