post方式:

在jsp页面头部加上  request.setcharacterencoding("UTF-8");

GET方式提交:

1.使用URL提交   decode(URL)
2.使用工具类

public class Exchange {
// 判断内容是否为空
public static String panduan(String str) {
String s = "";
if (str == null) {
System.out.println("无内容");

} else
s = str;
return s;
}

// 将字符串转化成INT类型
public static int exchangeIntoInt(String str) {
//System.out.println("工具类中获取的str"+str);
int d = 0;

try {
if (str == null) {
d = 0;
} else {
d = Integer.parseInt(str);
}
} catch (NumberFormatException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return d;
}

// 字符串乱码处理
public static String exchangeIntoString(String str) {
String ss = "";
try {
if (str == null) {
ss = "";
} else {
ss = new String(str.getBytes("ISO-8859-1"), "UTF-8");
}
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return ss;
}
// 将字符串转化成double类型
public static double exchangeIntoDouble(String str)
{
double d=0.0;
try {
if (str == null) {
d = 0.0;
} else {
d = Double.parseDouble(str);
}
} catch (NumberFormatException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
 
return d;
}
}
