encodingfilter.java

这是我做的一个Struts+Hibernate+Spring整合的例子 和大家分享一下

package com.thinkingfly.yz.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;
import javax.servlet.http.HttpServletRequest;

public class EncodingFilter implements Filter {

	private String encoding="UTF-8";
	
	//得到在web.xml文件设定的encoding过滤器的初始参数
	public void init(FilterConfig arg0) throws ServletException {
		this.encoding=arg0.getInitParameter("encoding");
	}
	//过滤字符
	public void doFilter(ServletRequest arg0, ServletResponse arg1,
			FilterChain arg2) throws IOException, ServletException {
	HttpServletRequest request=(HttpServletRequest)arg0;
	request.setCharacterEncoding(encoding);
	arg2.doFilter(request, arg1);
	}
	//销毁
	public void destroy() {
    this.encoding=null;
	}

}
