方法一：過濾器

	public void doFilter(ServletRequest request, ServletResponse response,
			FilterChain chain) throws IOException, ServletException {
		HttpServletRequest req=(HttpServletRequest) request;
		// http host頭攻擊漏洞校驗
		HttpServletResponse res = (HttpServletResponse) response;
        String requestHost = req.getHeader("host");
        if (requestHost != null && isRightHost(requestHost)){
            res.setStatus(403);
            return;
        }
		chain.doFilter(request, response);
	}
	// http host頭漏洞攻擊判斷
	public boolean isRightHost(String requestHost){
		if(requestHost.indexOf("www.xxx.com") == -1 && requestHost.indexOf("伺服器IP") == -1) {
			return true;
		}
        return false;
    }

　　方法二：nginx

if ($http_Host != '域名或ip:埠'){
return 403;
}
或
if ($http_Host !~*^域名或ip:埠$) {

 return 403;這裡可以自定義介面 參考

}

　　方法三：tomcat

Tomcat，修改server.xml檔案，配置Host的name屬性。

將Host裡的name修改為靜態的域名，如下：
