JSP乱码解决方案

在web.xml里面加

    <filter>
        <filter-name>char</filter-name>
        <filter-class>com.bbs.common.CharacterFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>char</filter-name>
        <url-pattern>/*</url-pattern>

    </filter-mapping>

 CharacterFilter类

package com.bbs.common;

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 CharacterFilter implements Filter {

    public void destroy() {
    }

    public void doFilter(ServletRequest request, ServletResponse response,
            FilterChain chain) throws IOException, ServletException {
        System.out.println("filter....");
        request.setCharacterEncoding("UTF-8");
        chain.doFilter(request, response);
    }

    public void init(FilterConfig filterConfig) throws ServletException {
        
    }

}
