Java Web garbled Filter Filter__java

We all know that in the JSP code is the most annoying things, some garbled out of the inexplicable, to the development of a great deal of trouble, but to make a garbled filter on everything is resolved, after the configuration, you do not need to be in the page to do transcoding and so on.

  First, write a filter class, as follows: package 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;   import javax.servlet.http.httpservletrequest;      public class  pageencodingfilter implements filter{          private  string encoding =  "UTF-8";       protected FilterConfig  filterconfig;                      public void init (Filterconfig filterconfig)  throws ServletException  {           this.filterconfig = filterconfig;            //the default encoding for this filter is UTF-8, but you can also set your own code       in Web.xml configuration file       if (Filterconfig.getinitparameter ("encoding")  != null)                 encoding =  Filterconfig.getinitparameter ("encoding");       }           public void dofilter (servletrequest srequset, servletresponse  sresponse,               filterchain  filterchain)  throws IOException, ServletException {            HttpServletRequest request =  (HttpServletRequest) srequset;         &NBsp;  request.setcharacterencoding (encoding);            filterchain.dofilter (srequset, sresponse);       }               public void destroy ()  {            this.encoding = null;       }      }  

Then, in the Web.xml configuration, as follows:

  <filter>           <filter-name>encoding </filter-name>           <filter-class>filter. pageencodingfilter</filter-class>           < init-param>               < param-name>encoding</param-name>                <param-value>UTF-8</param-value>            </init-param>       </filter>               <filter-mapping>            <filter-name>Encoding</filter-name>            <url-pattern>/*</url-pattern>       </filter-mapping>  

Here, everything is OK, you can rest assured that the code, and will not worry about the occurrence of garbled.
