What should I do if java characters are garbled?

What to do if java characters are garbled

I tried all the ways to set the encoding:

1. Re-encode the string and then decode it

name = URLEncoder.encode(name, "ISO-8859-1");
 name = URLDecoder.decode(name, "UTF-8");

2. Set the encoding

name=new String(name.getBytes(),"UTF-8");

3. Set the encoding

//利用getBytes将unicode字符串转成UTF-8格式的字节数组
 String name=request.getParameter("name");
  byte[] utf8Bytes = name.getBytes("utf-8");
//然后用utf-8 对这个字节数组解码成新的字符串
  name = new String(utf8Bytes, "utf-8");

4. In the sevlet or there are parameters passed through the page jump

request.setCharacterEncoding("utf-8");

Usually This problem doesn't bother me at all. The key this time is to pass the jsp value into the jsp page with java code embedded in it, which is more complicated.

I tried the above methods to no avail;

Finally Using

, the first line of the console displays Wu Chenggui (using name = new String (name.getBytes("ISO8859-1"), "UTF-8");) after

What is used is

<%
    //1.获得要查询的手环编号
       request.setCharacterEncoding("utf-8");
       String name=request.getParameter("name");

Although others say that using name = new String (name.getBytes("ISO-8859-1"), "UTF-8"); is informal, but it is practical!
