ServletJsp中解决乱码问题

在post方法中，只需要设置：request.setCharacterEncoding("UTF-8");

在get方法里面可以这样：

String username=request.getParameter("username");

String username=new String(username.getBytes("iso-8859-1"),"UTF-8");

System.out.println(username);

jsp中：<a href="ThreadSrevlet?name=中国" >点击</a>

String name=request.getParameter("name");

String name=new String(username.getBytes("iso-8859-1"),"UTF-8");

System.out.println(name);

在Cookie中，可以用：

Cookie cookie = new Cookie("cookie",URLEncoder.encode("您好！","UTF-8") );

Cookie[] cookies = request.getCookies();

if (cookies[i].getName().equals("cookie")) {

cookie2 = URLDecoder.decode(cookies[i].getValue(),"UTF-8");

}
