java.lang.ClassNotFoundException: com.itheima.web.filter.MyFilter为什么找不到配置文件没有问题啊？

myFilter
com.itheima.web.filter.MyFilter


myFilter
/*


public class MyFilter implements Filter {
public void destroy() {}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
chain.doFilter(request, response);
HttpServletRequest req=(HttpServletRequest) request;
req=new MyRequest(req); //把HttpServletRequest包装成MyRequest
chain.doFilter(req,response);
}
public void init(FilterConfig fConfig) throws ServletException {} }

如果这个filter不是自定义的filter，那么可能是没有导入相关的jar包；

我不会~~~但还是要微笑~~~：）
