具体的使用方法你可以在google上搜索 &filter 过滤器&，FilterConfig可以获取部署描述符文件（web.xml）中分配的过滤器初始化参数。针对你的问题回答，结果就是说FilterConfig可以获得web.xml中，以 filter 作为描述标签内的参数。
定义：FilterConfig对象提供对servlet环境及web.xml文件中指派的过滤器名的访问。FilterConfig对象具有一个getInitParameter方法，它能够访问部署描述符文件（web.xml）中分配的过滤器初始化参数。
实例：将下面的代码加入到web.xml中，试用FilterConfig就可以获得以 filter 作为描述标签内的参数。
&!-- The Cache Filter --&&filter&&!-- 设计过滤处理类，生成静态页面 --&&filter-name&CacheFilter&/filter-name&&filter-class&com.jspbook.CacheFilter&/filter-class&
&!-- 不需要缓存的URL --&&init-param&¶m-name&/TimeMonger.jsp&/param-name&¶m-value&nocache&/param-value&&/init-param&&init-param&¶m-name&/TestCache.jsp&/param-name&¶m-value&nocache&/param-value&&/init-param&&!-- 缓存超时时间, 单位为秒 --&&init-param&¶m-name&cacheTimeout&/param-name&¶m-value&600&/param-value&&/init-param&
&!-- 是否根据浏览器不同的地区设置进行缓存(生成的缓存文件为 test.jspid=1_zh_CN 的格式) --&&init-param&¶m-name&locale-sensitive&/param-name&¶m-value&true&/param-value&&/init-param&
&/filter&&filter-mapping&&filter-name&CacheFilter&/filter-name&&url-pattern&*.jsp&/url-pattern&&/filter-mapping& 用法：
filterConfig.getInitParameter("locale-sensitive"); 得到的就是 turefilterConfig.getInitParameter("cacheTimeout"); 得到的就是 600filterConfig.getInitParameter(request.getRequestURI()); 得到的就是param-name 对应的 param-value 值
过滤处理类：
public class CacheFilter implements Filter {ServletCFilterClong cacheTimeout = Long.MAX_VALUE;
public void doFilter(ServletRequest req, ServletResponse res,FilterChain chain) throws IOException, ServletException {HttpServletRequest request = (HttpServletRequest)HttpServletResponse response = (HttpServletResponse)
// check if was a resource that shouldn't be cached.String r = sc.getRealPath("");String path = fc.getInitParameter(request.getRequestURI());if (path != null && path.equals("nocache")) {chain.doFilter(request, response);}path = r +
public void init(FilterConfig filterConfig) {this.fc = filterCString ct = fc.getInitParameter("cacheTimeout");if (ct != null) {cacheTimeout = 60 * 1000 * Long.parseLong(ct);}this.sc = filterConfig.getServletContext();}
public void destroy() {this.sc =this.fc =}}
