1, form get method to submit parameters garbled, because the default tomcat according to the iso-8859-1 for url encoding so the corresponding conversion:
@ First, set the request Encoding Method on the acceptance parameter page or servlet, for example: request. setCharacterEncoding ("UTF-8 ");

@ The parameter changed encoding of the connection, which is the same as the characterencoding code above, new String (request. getParameter ("username"). getBytes ("iso-8859-1"), "UTF-8 ");

@ Modify the tomcat server. xml file, <Connector URIEncoding = "UTF-8" connectionTimeout = "20000" port = "8080" protocol = "HTTP/1.1" redirectPort = "8443"/>

@ The above method seems to have multiple parameters for ie6, The & symbol between parameters will be changed ??, I don't know how to solve it.

2. The parameters submitted by form post are garbled. There are two simple methods;

@ First, set the request Encoding Method on the acceptance parameter page or servlet, for example, request. setCharacterEncoding ("utf-8"); the UTF-8 encoding here is consistent with the contentType or pageEncoding of the page on which you pass the parameters.

@ Compile the filter. The method is omitted.

3. javascript uses url to pass Chinese parameter garbled characters to jsp pages (reproduced)

@ Solution: encode the Chinese parameter twice before passing the parameter. After obtaining the parameter on the jsp page, decode the Chinese parameter once. The Chinese parameter will not become garbled!

Example:
<% @ Page language = "java" contentType = "text/html; charset = UTF-8"

PageEncoding = "UTF-8" %>

<% @ Page import = "java.net. *" %>

String str0 = "";

String str1 = "";

If (request. getParameter ("param0 ")! = Null ){

Str0 = request. getParameter ("param0"); // get Chinese parameters directly

}

Try {

If (request. getParameter ("param1 ")! = Null ){

Str1 = URLDecoder. decode (request. getParameter ("param1"), "UTF-8"); // decodes Chinese Parameters

}

} Catch (Exception e ){

E. printStackTrace ();

}
