Servlet Chinese garbled problem

1. JSP page to write Chinese

 

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>

    Ensure that contentType, pageEncoding and browser encoding are all UTF-8, so there will be no garbled characters

 

 

2. Form submission in Chinese

 

<%
    request.setCharacterEncoding("UTF-8");
%>
<%=
    request.getParameter("message")
%>

     Before using request to get parameters, set the encoding first.

 

 

3. Chinese submitted through the get method

 

<%
   request.setCharacterEncoding("UTF-8");
   String msg = new String(request.getParameter("message").getBytes("iso-8859-1"), "UTF-8");
%>
<%=
    msg
%>

   The get mode Chinese is encoded with Iso-8859-1 by default.

     The first method: first decode Chinese, and then use UTF-8 encoding.

The second method: configure useBodyEncodingForURI="true"      in tomcat's server.xml file ;

         Then set request.setCharacterEncoding("UTF-8");
