访问时使用相对路径,例如:<IMG height=37 src="/images/cms/indexpic/index_20.jpg" width=341>
现在利用这个项目复制出一个新的项目,Web Context-root设置成/new,部署到Tomcat的webapps\new目录,这时使用相对路径访问出现问题,之前的/images/cms/indexpic/index_20.jpg需要改为new/images/cms/indexpic/index_20.jpg才能访问到,但项目规模较大,不可能在每个相对路径前面都加上<%=request.getContextPath()%>,有没有办法通过配置的方式解决这个问题?
3 个解决方案
#1
没什么解决办法,路径不对肯定访问不了
除非装两个tomcat,端口不同
#2
没有更好办法,不过你可以在jsp页面的<head></head>标签前加上<base>标签中设置一下路径
#3
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
