Everyone in the development process of JSP, often the problem of Chinese garbled, may be one to haunt you, I am now in the development of JSP encountered in Chinese garbled problems and solutions to write for your reference.
One, JSP page display garbled
The following display page (display.jsp) will appear garbled:
<TITLE>JSP's Chinese processing </title>
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 ">
<body>
<%
Out.print ("Chinese Processing of JSP");
%>
</body>
For different Web servers and different JDK versions, the processing results are not the same. Reason: The server uses different encoding methods and browsers to different characters display results. Workaround: Specify the Encoding Method (GB2312) in the JSP page, that is, the first line of the page plus: <%@ page contenttype= "text/html;" charset=gb2312 "%>, you can eliminate garbled." The complete page is as follows:
<%@ page contenttype= "text/html; charset=gb2312 "%>
<TITLE>JSP's Chinese processing </title>
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 ">
<body>
<%
Out.print ("Chinese Processing of JSP");
%>
</body>
second, the form submitted in Chinese when there are garbled
Below is a submission page (submit.jsp) with the following code:
<TITLE>JSP's Chinese processing </title>
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 ">
<body>
<form name= "Form1" method= "Post" action= "process.jsp" >
<div align= "center" >
<input type= "text" name= "name" >
<input type= "Submit" name= "submit" value= "Submit" >
</div>
</form>
</body>
The following is the Process page (process.jsp) code:
<%@ page contenttype= "text/html; charset=gb2312 "%>
<TITLE>JSP's Chinese processing </title>
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 ">
<body>
<%=request.getparameter ("name")%>
</body>
If the submit.jsp submit English characters can be displayed correctly, if the submission of Chinese will appear garbled. Reason: Browsers use UTF-8 encoding to send requests by default, while UTF-8 and GB2312 encodings are different when they represent characters, which can result in unrecognized characters. Solution: Through the request.secharacterencoding ("gb2312") to the request for unified coding, the realization of the normal Chinese display. The modified process.jsp code is as follows:
<%@ page contenttype= "text/html; charset=gb2312 "%>
<%
Request.secharacterencoding ("gb2312");
%>
<TITLE>JSP's Chinese processing </title>
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 ">
<body>
<%=request.getparameter ("name")%>
</body>
third, the database connection appears garbled
As long as the Chinese-related places are all garbled, the solution: in the database URL of database add USEUNICODE=TRUE&CHARACTERENCODING=GBK OK.
Four, the database display garbled
In mysql4.1.0, varchar type, text type will appear in Chinese garbled, for the varchar type to set it as binary attribute can solve the Chinese problem, for text type to use a code conversion class to deal with, realize as follows:
public class Convert {
/** converts the iso-8859-1 code into GB2312.
*/
public static string ISOTOGB (String iso) {
String GB;
try{
if (Iso.equals ("") | | ISO = NULL) {
Return "";
}
else{
ISO = Iso.trim ();
GB = new String (iso.getbytes ("iso-8859-1"), "GB2312");
return GB;
}
}
catch (Exception e) {
System.err.print ("Encoding conversion Error:" +e.getmessage ());
Return "";
}
}
}
By compiling it into class, you can invoke the static method Isotogb () of the Convert class to convert the encoding.
