解決jsp開發中的所有中文問題 對serverlet設定過濾器__js

首先編寫過濾器代碼在src目錄下

 

 package filter;

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class MyFilter implements Filter {
private FilterConfig fc;

public void init(FilterConfig fc) throws ServletException {
  // TODO Auto-generated method stub
  this.fc=fc;
}

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
  // TODO Auto-generated method stub
  request.setCharacterEncoding("gb2312");
  response.setCharacterEncoding("gb2312");
  chain.doFilter(request,response);
}

public void destroy() {
  // TODO Auto-generated method stub
 
}

}

web.xml中的配置:

<filter>
   <filter-name>Set Character Encoding</filter-name>
   <filter-class>com.XX.XX.listener.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>
   <servlet-name>action</servlet-name>
</filter-mapping>
<filter-mapping>
   <filter-name>Set Character Encoding</filter-name>
   <url-patten>/*</url-patten>
</filter-mapping>
