html中获取工程路径:
<% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %>
var localObj = window.location;
var contextPath = localObj.pathname.split("/")[1];
var basePath = localObj.protocol+"//"+localObj.host+"/"+contextPath;String path = ServletActionContext.getRequest().getRealPath(relativePath);
