Java字符串跟ASCII码互转

1.由于项目中遇到,在服务器端起的jar包程序,给前台发消息后,前段收到的消息出现乱码情况,所以采取在后才发消息前先把消息字符串转成ASCII码再发往前台,前台采取在收到后台消息先把ASCII码转成字符串的解决方案进行解决。

1)将字符串转成ASCII的Java方法

public static String stringToAscii(String value)
{
StringBuffer sbu = new StringBuffer();
char[] chars = value.toCharArray();
for (int i = 0; i < chars.length; i++) {
if(i != chars.length - 1)
{
sbu.append((int)chars[i]).append(",");
}
else {
sbu.append((int)chars[i]);
}
}
return sbu.toString();
}

2)将ASCII转成字符串的java方法

public static String asciiToString(String value)
{
StringBuffer sbu = new StringBuffer();
String[] chars = value.split(",");
for (int i = 0; i < chars.length; i++) {
sbu.append((char) Integer.parseInt(chars[i]));
}
return sbu.toString();
}

main方法测试:

public static void main(String[] args) {

              String str = "{name:1234,password:4444}";
String asciiResult = stringToAscii(str);
System.out.println(asciiResult);
String stringResult = asciiToString(asciiResult);
System.out.println(stringResult);
}

输出:

123,110,97,109,101,58,49,50,51,52,44,112,97,115,115,119,111,114,100,58,52,52,52,52,125
{name:1234,password:4444}
