Solution to Chinese garbled characters displayed in Java

Solution to java displaying garbled characters:

1. UTF8 solves the problem of JSP Chinese garbled characters

Generally speaking, at the beginning of each page, add :

<%@ page language="java" contentType="text/html; charset=UTF-8"     pageEncoding="UTF-8"%>
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<% request.setCharacterEncoding("UTF-8"); %>

charset=UTF-8 is used to specify the encoding method output by JSP to the client as "UTF-8";

pageEncoding="UTF-8", in order to allow the JSP engine to It can correctly decode JSP pages containing Chinese characters, which is very effective in LINUX;

request.setCharacterEncoding("UTF-8"); encodes the request in Chinese.

Sometimes, this still cannot solve the problem, and you need to deal with it like this:

String msg = request.getParameter("message");  String str=new String(msg.getBytes("ISO-8859-1"),"UTF-8");  out.println(st);

2. Tomcat 5.5 Chinese garbled code

<filter>   

<filter-name>Set   Character   Encoding</filter-name>   

<filter-class>filters.SetCharacterEncodingFilter</filter-class>   

<init-param>   

<param-name>encoding</param-name>   

<param-value>GBK</param-value>   

</init-param>   

</filter>   

<filter-mapping>   

<filter-name>Set   Character   Encoding</filter-name>   

<url-pattern>/*</url-pattern>   

</filter-mapping>

  enableLookups="false"   redirectPort="8443"   acceptCount="100"   
  debug="0"   connectionTimeout="20000"
