Java 删除Hexa消息的一部分以获得好消息

我尝试使用以下方法将十六进制字符字符串转换为字符串：

public String HexToString(String inputString){
    StringBuilder output = new StringBuilder();
    for (int i = 0; i < inputString.length(); i+=2) {
        String str = inputString.substring(i, i+2);
        output.append((char)Integer.parseInt(str, 16));
    }
    return output.toString();
}

公共字符串HexToString（字符串输入字符串）{
StringBuilder输出=新的StringBuilder（）；
对于（int i=0；i

输入为：

“4D442020000000020000000000000000008FFFFFFFF000000022200‌​0001b54d514852463220‌​20000000000000000141‌​4D5120434D504C333‌​202020020D75DB05811‌​51D020000000000000000‌​00000000000000000000‌​00000000000000000000‌​00202020202020202020‌​20202020202020202020‌​20202020202020202020‌​20202020202020202020‌​20202020202020202043‌​4D504C3C333202020‌​20202020202020202020‌​20000000000000000000‌​00000000020202020202‌​02020202020202020202‌​02020202020202020202‌​02020202020200000001‌​c7765626c6f6……”

这个方法可行，但问题是我的消息包含奇怪的字符。 转换后，我在标题中收到以下字符：“µMQHRF2”

问题是如何删除此标题？我应该在消息是在Hexa上还是在转换后执行此操作？如何从字符串中删除这些字符

您可以使用apache commons库。这里是链接

您的输入看起来如何？你希望得到什么？我的输入是六边形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……）当我转换时，我一开始就收到了那些强字符，我想使用“MD”中的方法输出删除转换“4d44”，那么“µMQHRF2”是什么意思“在标题中？您的输入示例包含不可见的unicode字符，如以下代码段：-您应该去掉这些字符。此外，当您解码干净的版本时（

），作为字符串得到的不是字符串，但显然是来自二进制协议（来自某个消息队列）它不是我的目标！我想从消息中删除第一个字符！对于exemaple，消息是“xcds&é&&é”é&这是示例“我想删除这个”xcds&é&&é&é&é&é&é&é”é&“消息将是“这是示例”
