获取域名，如：http://f0rb.iteye.com/java

StringBuffer url = request.getRequestURL();
String tempContextUrl = url.delete(url.length() - request.getRequestURI().length(), url.length()).append("/").toString();

获取带部署环境上下文的域名，如： http://www.iteye.com/admin/app

　　这个方法是在别人那看见的，我用到时候request.getServletContext()是报错的；url

StringBuffer url = request.getRequestURL();
String tempContextUrl = url.delete(url.length() - request.getRequestURI().length(), url.length()).append(request.getServletContext().getContextPath()).append("/").toString();

　　因而我看了下改为了以下：spa

StringBuffer url = request.getRequestURL();
		String tempContextUrl = url.delete(url.length() - request.getRequestURI().length(), url.length()).append(request.getSession().getServletContext().getContextPath()).append("/").toString();
