JAVA byte类型转String类型

问题:

        RSA加密 byte类型转String类型,格式转换之后内容变了,解密解不出来

第一种方式:使用"ISO-8859-1"编码,使用此方式编码返回结果会乱码

例如:

public static void main(String[] args) throws UnsupportedEncodingException {
        String text = "你好哇aaaaaaaaa";
        byte[] byteResult = text.getBytes("ISO-8859-1");
        System.out.println(byteResult);
        String textResult = new String(byteResult,"ISO-8859-1");
        System.out.println(textResult);
    }

打印结果:

[B@4783da3f
???aaaaaaaaa

Process finished with exit code 0

第二种方式:使用Base64.encodeBase64String转码

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

打印结果:

[B@4783da3f
5L2g5aW95ZOHYWFhYWFhYWFh
[B@439f5b3d
你好哇aaaaaaaaa

Process finished with exit code 0

我采用的第二种方式,避免字符乱码
