漏扫异常处理

服务器漏扫出bug

1.远端WWW服务支持TRACE请求 

这个主要是http1.1 保持405 ，不是200就可以，禁止这个还是参照网上处理办法

多种方案尝试后：

采用了过滤器：

@Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        HttpServletResponse httpResponse = (HttpServletResponse) response;
        if ("TRACE".equalsIgnoreCase(httpRequest.getMethod())) {
            httpResponse.setStatus(HttpServletResponse.SC_METHOD_NOT_ALLOWED);
            return;
        }
        chain.doFilter(request, response);
    }

 curl -v -X TRACE -I localhost:10302

2. 可通过HTTP获取远端WWW服务信息

暂时不解决
