String.getBytes()方法中的中文编码问题
String的getBytes()方法是得到一个系统默认的编码格式的字节数组
getBytes("utf-8") 得到一个UTF-8格式的字节数组
把String转换成bytes，各种编码转换成的bytes不同，比如UTF-8每个汉字转成3bytes，而GBK转成2bytes，所以要说明编码方式，否则用缺省编码。
都是将一个string类型的字符串转换成byte类型并且存入一个byte数组中。
在java中的所有数据底层都是字节，字节数据可以存入到byte数组。
存储字符数据时(字符串就是字符数据)，会先进行查表，然后将查询的结果写入设备，读取时也是先查表，把查到的内容打印到显示设备上
getBytes()是使用默认的字符集进行转换，getBytes(“utf-8”)是使用UTF-8编码表进行转换。

在Java中,String的getBytes()方法是得到一个操作系统默认的编码格式的字节数组。这表示在不同的操作系统下,返回的东西不一样!
String.getBytes(Stringdecode)方法会根据指定的decode编码返回某字符串在该编码下的byte数组表示,如:
byte[]b_gbk = "中".getBytes("GBK");
byte[] b_utf8 = "中".getBytes("UTF-8");
byte[] b_iso88591 = "中".getBytes("ISO8859-1");
将分别返回"中"这个汉字在GBK、UTF-8和ISO8859-1编码下的byte数组表示,此时
b_gbk的长度为2,
b_utf8的长度为3,
b_iso88591的长度为1。
而与getBytes相对的,可以通过new String(byte[],decode)的方式来还原这个"中"字,
这个new String(byte[],decode)实际是使用指定的编码decode来将byte[]解析成字符串.
String s_gbk = new String(b_gbk,"GBK");
String s_utf8 = new String(b_utf8,"UTF-8");
String s_iso88591 = new String(b_iso88591,"ISO8859-1");
通过输出s_gbk、s_utf8和s_iso88591,会发现s_gbk和s_utf8都是"中",而只有s_iso88591是一个不被识别的字符（可以理解为乱码）,为什么使用ISO8859-1编码再组合之后,无法还原"中"字？原因很简单,因为ISO8859-1编码的编码表根本就不包含汉字字符,当然也就无法通过"中".getBytes("ISO8859-1");来得到正确的"中"字在ISO8859-1中的编码值了,所以，再通过newString()来还原就更是无从谈起。
因此,通过String.getBytes(Stringdecode)方法来得到byte[]时,一定要确定decode的编码表中确实存在String表示的码值,这样得到的byte[]数组才能正确被还原。
注意：
有时候,为了让中文字符适应某些特殊要求(如httpheader要求其内容必须为iso8859-1编码),可能会通过将中文字符按照字节方式来编码的情况,如:
Strings_iso88591 = newString("中".getBytes("UTF-8"),"ISO8859-1"),这样得到的s_iso8859-1字符串实际是三个在ISO8859-1中的字符,在将这些字符传递到目的地后,目的地程序再通过相反的方式Strings_utf8 = newString(s_iso88591.getBytes("ISO8859-1"),"UTF-8")来得到正确的中文汉字"中"，这样就既保证了遵守协议规定、也支持中文。
