Two levels: JSP input, JSP acquisition

1. enter Chinese on JSP page, no garbled characters after request page

1) Ensure that the encoding format of the JSP page is UTF-8

<%@ page language= "java" contenttype= "text/html; Charset=utf-8 "pageencoding=" UTF-8 "%>

CharSet pageencoding Consistent, value is UTF-8

2) browser display character encoding consistent with the requested JSP page encoding

2. get The Chinese parameter value in the JSP page: the encoding used by the default parameter in transit is iso-8859-1

1) for post requests: call request.setcharacterencoding ("UTF-8") before getting the parameters;

1 <%2 request.setcharacterencoding ("UTF-8");3         4  %>5Username<%=Request.getparameter ("username") %>

　　2) for GET requests:

① first get the parameters, then decode, then encode

1 <%2             StringVal=Request.getparameter ("username");3             Stringusername= New String(Val.getbytes ("iso-8859-1"),"UTF-8");4 Out.print (username);5             6   %>

② General Method: Set Tomcat server.xml to add usebodyencodingforuri= "true". This can be used in the same way as the Post method to solve Chinese garbled

1 <  port= "8080"  protocol= "http/1.1"2connectiontimeout  = "20000"3redirectport= "8443"4  Usebodyencodingforuri= "true"/>

Reference: The Usebodyencodingforuri property of the http://localhost:8080/docs/config/index.html document. Add this property for connector, set to True

Also modify the Tomcat mappings in Eclipse to add the same content

Reference:

Tomcat can start normally in 1.eclipse, but the browser cannot access the Tomcat homepage problem solving
