JSP中URL编码问题?

Question

URL中传递的参数是&name=URLEncoder.encode("中国人","utf-8")编码的,然后页面中使用out.println(request.getParameter("bookname"));或out.println(URLDecoder.decode(request.getParameter("bookname")));取出来的是乱码,如何解决,当前页面为utf-8编码?

Answer 1

编码时指定UTF-8 解码时也要指定UTF-8并且你传入的参数名是“name”，而读取时的参数名是“bookname”。写错了吧

Answer 2

在tomcat下的配置文件server.xml中在端口8080处加入URIEncoding="UTF-8"

Answer 3

request.setCharacterEncoding("UTF-8");
String name=request.getParameter("bookname");
out.println(name);这样子还是不行

Answer 4

name=new String(request.getParameter("name").trim().getBytes("8859_1"),"utf-8");
浏览器默认使用8859_1编码
