encode包的java文件(字符编码过滤器)：

SetCharacterEncodingFilter.java :

package com.cjq.demo.encode;

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;

@Override
public void destroy() {
this.encoding = null;
this.filterConfig = null;
}

@Override
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);
}

@Override
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 if(value.equalsIgnoreCase("yes")){
this.ignore = true;
}else{
this.ignore = false;
}
}

protected String selectEncoding(ServletRequest request){
return (this.encoding);
}
}

servlet包的java文件，此处也用于字符编码处理：

DemoActionServlet.java:

package com.cjq.demo.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionServlet;

public class DemoActionServlet extends ActionServlet {

@Override
protected void process(HttpServletRequest request,
HttpServletResponse response) throws IOException, ServletException {
request.setCharacterEncoding("GBK");
super.process(request, response);
}

}
