Solution 1 (If there are many garbled parameters, it will be less efficient)
The default encoding of the browser is ISO-8859-1, and the back-end Servlet receives the request parameters. Decode according to ISO-8859-1 to obtain a binary stream, and then encode it with UTF-8.
Sample code:
// 获得请求参数
String queryString = request.getQueryString();
// 按照ISO-8859-1方式解码
byte[] bytes = queryString.getBytes("ISO-8859-1");
// 按照UTF-8编码
String param = new String(bytes,"UTF-8");
Solution 2 (this method only supports get request)
Modify the server (tomcat) configuration: in server.xml, the default is ISO-8859-1 (not shown), we can add UTF-8
Solution 3 (this method only supports post request)
Set the request parameter encoding directly in the servlet--Recommendation
//设置请求参数编码
request.setCharacterEncoding("UTF-8");
Response garbled code--Response
// 设置MIME类型
response.setContentType("text/html");
// 设置编码
response.setCharacterEncoding("UTF-8");
//设置编码（简写）
response.setContentType("text/html;charset=utf-8");
