java中每次刷新页面时如何获取URL地址？ 我正在做的项目需要 URL(域名)，而每个页面都会刷新..!!

Answer 1

用户请求对象获取url

// Getting servlet request URL

String url = request.getRequestURL().toString();

// Getting servlet request query string.

String queryString = request.getQueryString();



// Getting request information without the hostname.

String uri = request.getRequestURI();
