MyEclipse Development of Web project coding problem Solving

One, the development tool can modify the coding place:

1) Window----Preferences---Content Types---Text

Select the file you want to set up, enter "GBK or UTF-8" in the default encoding, and click Update later

2) Window---Preferences---Workspace Text file encoding

Enter "GBK or UTF-8" in the selection box after other, click Applay and OK

3) Right click on Project, file. Select Properties--Text file encoding

Also enter "GBK or UTF-8" in the selection box after other, click Applay and OK

The place where the code can be modified in the document:

Only files that have encoding settings, such as JSP files and HTML files, are limited to

1) <%@ page language= "java" import= "java.util.*" pageencoding= "GBK"%>

2) <meta http-equiv= "Content-type" content= "text/html; charset=gbk " />

Third, using filter to implement the coding filter

1) Filter Processing class

Create a Java class that implements the filter interface

package com.hchx.filter;import java.io.ioexception;import javax.servlet.filter;import  javax.servlet.filterchain;import javax.servlet.filterconfig;import javax.servlet.servletexception; import javax.servlet.servletrequest;import javax.servlet.servletresponse;/** *  *   @ClassName: characterfilter *  @Description the implementation class  *  @author of: |--  coded filters  GNODIAD *  @date  2014-11-13  Morning 09:27:50 */public class characterfilter  implements Filter{//  declaration Code processing Parameters private string srccharset;private string  Targetcharset;public void destroy ()  {// TODO  pending Method}public void dofilter ( Servletrequest request, servletresponse response,filterchain chain)  throws  Ioexception, servletexception {system.out.println ("Start encoding Filter ...");//  In the console print prompt request.setcharacterencoding (srccharset);//  settings pleaseCoding response.setcharacterencoding (Targetcharset);//  Set response encoding Chain.dofilter (request, response);  //   Backward pass}public void init (filterconfig config)  throws servletexception { Srccharset = config.getinitparameter ("srcCharSet"); targetcharset = config.getinitparameter ("Targetcharset");}}

2) Configure the filter in Web. xml

<filter><filter-name>charset</filter-name><filter-class> com.hchx.filter.characterfilter</filter-class><init-param><param-name>srccharset</ Param-name><param-value>gbk</param-value></init-param><init-param><param-name >targetcharset</param-name><param-value>gbk</param-value></init-param></filter ><filter-mapping><filter-name>charset</filter-name><url-pattern>/*</url-pattern ></filter-mapping>

Summary: Solve the coding problem, from these three aspects, the specific operation is different from individual development projects.
