garbled problems in Java

1 if the Tomcat server is used, add uriencoding= "UTF-8" after connector the label in Server.xml;

2 Using the Web filter:

(1), create a new class of Setcharacterencodingfilter.java:

Package com.util;
Import java.io.IOException;
Import javax.servlet.*;

public class Setcharacterencodingfilter implements filter{
protected String encoding = NULL;

protected Filterconfig filterconfig =null;

Protected Boolean ignore = true;

public void Destroy ()
{
this.encoding = null;
This.filterconfig = null;

}

 public void DoFilter (servletrequest request,servletresponse response,
     Filterchain chain) throws IOException, Servletexception
 {
    if (ignore| | (request.getcharacterencoding () = = null))
    {
    string encoding = selectencoding (request);
    if (encoding! = null)
     request.setcharacterencoding ( encoding);
   }
   chain.dofilter (request, response);
 }

public void init (Filterconfig filterconfig) throws Servletexception
{
This.filterconfig = Filterconfig;
Get initialization parameters
this.encoding = Filterconfig.getinitparameter ("encoding");
String value= filterconfig.getinitparameter ("ignore");
if (value ==null)
{
This.ignore = true;
} else if (Value.equalsignorecase ("true"))
{
This.ignore = true;
} else if (Value.equalsignorecase ("yes"))
{
This.ignore = true;
} else
This.ignore = false;
}

Protected String selectencoding (servletrequestrequest)
{
return (this.encoding);
}

}

(2) added in Web-app in Web. xml:

<!--define a filter and set its initialization parameters--><filter>
<filter-name>set characterencoding</filter-name>
<filter-class>com.util.SetCharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GB2312</param-value>
</init-param>
</filter>
<!--to develop a filter map--
<filter-mapping>
<filter-name>set characterencoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

3.<%@ page language= "java" import= "java.util.*,com.scce.entity.*" pageencoding= "Utf-8"%>

　　<Meta http-equiv= "content-type" content= "text/html; Charset=utf-8 ">

4.String name=new String (request.getparameter ("name"). GetBytes ("Iso8859-1"), "GBK");

New String (Filename.getbytes ("UTF-8"), "GBK")

5.request.setcharacterencoding ("GBK");

Response.setcontenttype ("TEXT/HTML;CHARSET=GBK");
