encodingfilter.java

实现了基本的增删改查和分页功能很简单的但是挺不错的适合初学者

package org.demo.util;

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 EncodingFilter implements Filter {
	FilterConfig filterconfig;
	public void destroy() {
		// TODO Auto-generated method stub

	}

	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain chain) throws IOException, ServletException {
		// TODO Auto-generated method stub
           String encoding=this.filterconfig.getInitParameter("encode");
           request.setCharacterEncoding(encoding);
           chain.doFilter(request, response);
	}

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

}
