From code to code-free,

 

@Controllerpublic class SearchController { @RequestMapping(value = "/s/{k}.html", method = RequestMethod.GET) public String search(@ModelAttribute("k") @PathVariable String k) { System.out.println("k=" + k); return "search/search"; }}

Page retrieval:

<div class="form-group">    <input type="text" class="form-control"> <Connector connectionTimeout="20000" port="80" protocol="HTTP/1.1" redirectPort="8443" useBodyEncodingForURI="true" URIEncoding="UTF-8"/>

The difference between URIEncoding and useBodyEncodingForURI is:

• URIEncoding is a unified re-encoding of the data of all GET requests,
• UseBodyEncodingForURI recodes data based on the request. setCharacterEncoding parameter of the page responding to the request. Different pages can be reencoded differently.

After modification, follow these steps:

@Controllerpublic class SearchController { @RequestMapping(value = "/s/{k}.html", method = RequestMethod.GET) public String search( @PathVariable String k, HttpServletRequest request) { String key = EncodingUtil.encodeStr(k); request.setAttribute("key", key); return "search/search"; }}

EncodingUtil：

public class EncodingUtil { public static String encodeStr(String str) { try { return new String(str.getBytes("ISO-8859-1"), "UTF-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); return null; } }}

Okay, the problem is solved.

However, this is obviously not the way that the goods are said to be invincible. Which big God has a better way? Thank you !!!
