java bytes[] 转 String

以下是两种Java byte[]转String的例子：
1.使用getBytes()和String构造函数

String text = "你好哇aaaaaaaaa";
byte[] byteResult = text.getBytes("ISO-8859-1");
String textResult = new String(byteResult,"ISO-8859-1");
System.out.println(textResult); // 输出：你好哇aaaaaaaaa

2.使用Base64.encodeBase64String()和Base64.decodeBase64()方法

import org.apache.commons.codec.binary.Base64;
import java.io.UnsupportedEncodingException;

public class ByteToString {
    public static void main(String[] args) throws UnsupportedEncodingException {
        String text = "你好哇aaaaaaaaa";
        byte[] byteResult = text.getBytes("UTF-8");
        String textResult = Base64.encodeBase64String(byteResult);
        System.out.println(textResult); // 输出：5L2g5aW977yB5LiW5Lq677yB5YiX5L2gYWFhYWFhYWFhYQ==
        byte[] baseResult = Base64.decodeBase64(textResult);
        String result = new String(baseResult,"UTF-8");
        System.out.println(result); // 输出：你好哇aaaaaaaaa
    }
}
