JSP页面获取服务器路径的方式
1.basePath方式
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>在url加入<%=basePath%>如：http://192.168.66.66:8089/xinfang/
2.直接请求服务器路径
${pageContext.request.contextPath}服务端获取服务器路径的方式
//获取远程服务器IP和端口
String serverIp=request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort();http://localhost:80/images/ocrtemp_1.png
获取本机IP地址
InetAddress address = InetAddress.getLocalHost();
String hostAddress = address.getHostAddress();192.168.66.66
SpringBoot
window.location.origin
