一、java获取web工程路径
1),在servlet可以用一下方法取得:
request.getRealPath(“/”) 例如:filepach = request.getRealPath(“/”) ”//upload//”;
2),不从jsp,或servlet中获取,只从普通java类中获取:
String path =
getClass().getProtectionDomain().getCodeSource().getLocation().getPath();
SAXReader() saxReader = new SAXReader();
if(path.indexOf(“WEB-INF”)>0){
path = path.substring(0,path.indexOf(“/WEB-INF/classes”) 16);
// ‘/WEB-INF/classes’为16位
document = saxReader.read(path filename);
}else{
document = saxReader.read(getClass().getResourceAsStream(filename));
}
weblogic tomcat 下都有效
String path =
getClass().getProtectionDomain().getCodeSource().getLocation().getPath();
<!--EndFragment-->
<%
//此方法是通用的,可以获取不同系统中应用项目的根目录
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
二、js获取web工程路径
var strFullPath=window.document.location.href;
var strPath=window.document.location.pathname;
var pos=strFullPath.indexOf(strPath);
var prePath=strFullPath.substring(0,pos);
var postPath=strPath.substring(0,strPath.substr(1).indexOf(‘/‘)+1);
var webPath=prePath+postPath;
