Java Web Chinese garbled processing note

One, the occurrence of Chinese garbled in the case of the following three kinds:

1. Two types of submissions for form form are garbled in Chinese

①get Submit ②post Submission

2. Hyperlinks (essentially get commits) appear garbled in Chinese

3, Sendredirect (garbled)

Second, the cause of garbled characters:

Browser encoding Utf-8 sending a request to the server will result in inconsistent encoding
So in the sending request is the first definition of the code, it will be a good solution to the problem of coding

Three, to solve garbled several simple ways:

Post method submission: The solution is as follows: Request.setcharacterencoding ("Utf-8");

The Get method uses this method still does not solve the problem is still garbled, for Get submit the processing method used

Encapsulation becomes a tool class to handle:

 Public class mytool{    publicstatic  string getnewstring (String str) {        string newstring ="";         Try {        newstringnew String (str.getbytes ("iso-8859-1"), "Utf-8");        } Catch (Exception e) {            e.printstacktrace ();        }         return newstring;}    }

Invoking the tool class:

String u = request.getparameter ("username");
mytool.getnewstring (U);

The way hyperlinks are submitted is the same as get commit processing

Four, browser-compatible version information issues, if IE6 or the following version, the second to third type will appear garbled

Hyperlink garbled and Sendredirect garbled
String Info=java.net.urlencoder encode ("hello. jpg", "utf-8");
<a href= "" + info> Test </a>
Response.sendredirect ("servlet address?") Username= "+ info);

Postscript:

On the server side is Chinese, in the response, but also to consider whether the browser is displayed correctly
Response.setcharacterencoding ("Utf-8");
Response.setcontenttype ("Text/html;charset=utf-8")
