encodingfilter.java

又一个课程设计 简易 JSP 论坛 功能较简单的那种, 界面上模仿了 Discuz JSP 本来就学的不行, 只是尽量实现了 MVC

package cn.ialvin.bbs.filter;

import java.io.IOException;

import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class EncodingFilter implements javax.servlet.Filter {

	public void destroy() {}

	public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException, ServletException {
		arg1.setCharacterEncoding("UTF-8");
		arg0.setCharacterEncoding("UTF-8");
		arg1.setContentType("text/HTML; charset=UTF-8");
		arg2.doFilter(arg0, arg1);
	}

	public void init(FilterConfig arg0) throws ServletException {}
}
