Tomcat 5 Chinese problem fjchenq Posted on 2005-1-20 9:03:00
The method of the previous handling Tomcat4 is found in Tomcat5 cannot be applied to the request directly through the URL, and the information is found to find the most perfect solution. It doesn't have to be converted every place, and it is normal from GET, and POST. Write a document, posted it, I hope that people who have the same problem are no longer like me :-)
Problem Description:
1 The data submitted by the form is garbled with the string returned by Request.getParameter ("XXX") or? ? 2 Directly via URL such as http: ///localhost/a.jsp? Name = China, such GET requests are garbled when using Request. GetParameter ("name"); Press Tomcat4 to set Filter Or use Request.SetCharacterencoding ("GBK");
Cause: 1 Tomcat J2EE Implementation Parameters Timed by the POST method prompt time processing parameters Using the default ISO-8859-1 Processing 2 Tomcat Submitted by the GET method to use the Query-String process with the post method is different. Handling method. (Different from Tomcat4, set the setcharacterenceeEncoding ("GBK").
Solution:
First all JSP files plus:
1 Implement a Filter. Set the processing character set to GBK. (There is a complete example in Tomcat's WebApps / Servlet-Examples directory. Please refer to Web.xml and SetcharacterencodingFilter.)
1) Just copy the% Tomcat installation directory% / webApps / servlets-example / web-inf / class / filter.class file to copy your webapp directory / filters, if there is no Filters directory, create one. 2) In your web.xml, add the following lines:
set character encoding filters.setcharacterencodingfilter Encoding GBK set character encoding / *
3) Complete.
2 GET method solution 1) Open Tomcat's server.xml file, find blocks, join the following line: uriencoding = "GBK" is complete, you should follow:
2) Restart Tomcat, everything is OK.
Perform the following JSP page page test is successful
<% @ Page ContentType = "Text / HTML; Charset = GB2312"%> <% @ page import = "java.util. *"%> <% string q = request.getParameter ("q"); q = q = = NULL? "No value": q;%>
News list Show </ title> <meta http-equiv = content-type content = "text / html; charSet = GB2312> < Meta http-equiv = prgma content = no-cache> <body> You submitted: <% = q%> <br> <form action = "tcnchar.jsp" method = "post"> Enter "in Chinese: <input type = "text" name = "q"> <input type = "submit" value = "OK"> <br> <a href="tcnchar.jsp?q= 中国"> By GET method submit </ form > </ Body> </ html></p>
<p>Test Results If you enter a text box or a bit chain will be displayed: You submit "China", explain success !!!!! http://blog.china-pub.com/more.asp?name=fjchenq&id=7326</p></div><div class="text-center mt-3 text-grey">
