package cn.hatzhou.servlet;import java.io.IOException;
import java.io.PrintWriter;import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;

FilterChain chian) throws IOException, ServletException {

HttpSession session = req.getSession();
if (session.getAttribute("username") != null) {

}else{
request.getRequestDispatcher("index.htm").forward(request, response);
}
} public void init(FilterConfig arg0) throws ServletException {
System.out.println("过滤器初始化");
}

}web.xml中过滤器是这样配置的
<filter>
<filter-name>LoginFilter</filter-name>
<filter-class>cn.hatzhou.servlet.LoginFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>LoginFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
问题就是 本来登录的页面很整齐,但是配置了过滤器之后图片显示叉叉,css基本也没用了,肿么办

解决方案 »

  1.   

    /*是过滤掉所有的，包括图片、js、css和html
    要么在加个路径如：/×××/*
    要么就改为*.jsp
      

  2.   

    web 里面有个初始化的 标签 将不需要过滤的文件 写上 xxx。js xxx。css 什么的  servlet 里获取 判断 应该就好了
      

  3.   

    css、图片之类可以不用过滤了，1楼的方法可行，lz研究下
