From code to code-free

 

I don't want to see you. The Master said: no code in mind, natural HD.

Let's get down to the truth.

Environment:

1. Tomcat7, jdk6
2. Spring + springmvc + mybatis
3. Maven

Problem: There is characterencodingfilter, and the controller processes GET request garbled characters.

Controller:

@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" style = "width: pixel; "Name =" K "id =" K "Placeholder =" what do you want to search? Sn ~ Hash code ~ "Value =" $ {k} "/> </div>

After checking on the Internet, the more reliable solution is to modify the server. xml configuration in Tomcat and add the configuration in the connector node:useBodyEncodingForURI="true" URIEncoding="UTF-8";

    <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:

OK, no problem! So I am looking for a jspspace provider to modify the configuration. This is what we say:

How can I be troubled by the cool smell of money as a rich technician!

So I collected the information myself, changed the code again, and re-encoded it in the controller:

Controller:

@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 !!!
