页面传入后台的参数 乱码问题处理

JS里JSON传入时，data:'name='+escape(escape("大大大"))；

action类中要调用unescape(name)进行解码 将%u5927%u5927%u5927转为“大大大”存入数据库



public static String unescape(String src) {
if (src == null)
return null;
StringBuffer tmp = new StringBuffer();
tmp.ensureCapacity(src.length());
int lastPos = 0, pos = 0;
char ch;
while (lastPos < src.length()) {
pos = src.indexOf("%", lastPos);
if (pos == lastPos) {
if (src.charAt(pos + 1) == 'u') {
ch = (char) Integer.parseInt(src
.substring(pos + 2, pos + 6), 16);
tmp.append(ch);
lastPos = pos + 6;
} else if (src.charAt(pos + 1) == ' '
|| src.charAt(pos + 1) == ';') {
tmp.append(src.substring(pos, pos + 1));
lastPos = pos + 1;
} else {
ch = (char) Integer.parseInt(src
.substring(pos + 1, pos + 3), 16);
tmp.append(ch);
lastPos = pos + 3;
}
} else {
if (pos == -1) {
tmp.append(src.substring(lastPos));
lastPos = src.length();
} else {
tmp.append(src.substring(lastPos, pos));
lastPos = pos;
}
}
}
return tmp.toString();
}
