String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 输出: path:/E_WuLiu basePath:http://localhost:8080/E_WuLiu/ getContextPath():得到当前应用的根目录 getScheme():它返回当前请求所使用的协议。
response.setContentType(“text/html;charset=UTF-8”); 3、获取虚拟路径 request.getContextPath() 最终得到的是 /BookStore04
System.out.println("---默认相对路径:取得路径不同---"); File file =new File(".\\test1.txt"); System.out.println(file.getPath()); System.out.println(file.getAbsolutePath()); System.out.println(file.getCanonicalPath()); System.out.println("---默认绝对路径:取得路径相同---"); File ...
2.2、getAbsolutePath()返回的其实是user.dir+getPath()的内容,从上面看:D:\workspace\java_io\.\src\test.txt,D:\workspace\java_io\..\src\test.txt,可以得出。 2.3、getCanonicalPath()返回的就是标准的将符号完全解析的路径
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%> <%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt_rt"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort(...
首先来介绍File对象中 getPath()方法,getAbsolutePath()方法及重点要说的getCanonicalPath()方法; java.io.File包含三种确定文件路径的方法: getPath():此文件路径方法将抽象路径名作为String返回。如果字符串pathname用于创建File对象,则getPath()只返回pathname参数,例如File file = new File(pathname)构造参数pathnam...
