struts+spring+hibernate的web应用【8】

第二十一部分：接着编写 web.xml ，代码如下：

 

<? xml version="1.0" encoding="GB2312" ?>

     </ filter > 
 
     < filter-mapping > 
         < filter-name > Set Character Encoding </ filter-name > 
         < url-pattern > /* </ url-pattern > 
     </ filter-mapping > 
    
     <!--

       --> 
       < listener >

     <!--  The Welcome File List  -->

     </ taglib > 
 </ web-app > 

 

第二十二部分：大家可能注意到了这里有个 Set Character Encoding 过滤器。我们需要在 com.game.commons 包中

              新建 SetCharacterEncodingFilter 类来过滤编码，类的代码如下：

 

package  com.game.commons;

 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;

 public   class  SetCharacterEncodingFilter  implements  Filter   {
 protected  String encoding  =   null ;
 protected  FilterConfig filterConfig  =   null ;
 protected   boolean  ignore  =   true ;

 public   void  init(FilterConfig filterConfig)  throws  ServletException   {
 this .filterConfig = filterConfig;
 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 
 this .ignore = false ;
} 
 
  public   void  doFilter(ServletRequest request, ServletResponse response, FilterChain chain)  throws  IOException, ServletException   {
 //  TODO 自动生成方法存根 
  if  (ignore  ||  (request.getCharacterEncoding()  ==   null ))   {
String encoding  =  selectEncoding(request);
 if  (encoding  !=   null )
request.setCharacterEncoding(encoding);
} 
chain.doFilter(request, response);
} 
 
  public   void  destroy()   {
 //  TODO 自动生成方法存根 
 this .encoding  =   null ;
 this .filterConfig  =   null ;
} 
 
  protected  String selectEncoding(ServletRequest request)   {
 return  ( this .encoding);
} 
} 

 

 

第二十三部分：为了项目的测试运行，我们还需要配置 log4j.properties ，这个文件放在 src 根目录下。代码如下：

 log4j.rootLogger=info,console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.SimpleLayout
log4j.logger.com.wehave=DEBUG
# log4j.logger.org.springframework=DEBUG
# SqlMap logging configuration
# log4j.logger.com.ibatis=DEBUG
# log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
# log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
# log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.java.sql.Connection=DEBUG
# log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
#log4j.logger.java.sql.ResultSet=DEBUG
