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。
File file =newFile(".\\src\\test.txt"); System.out.println(file.getPath()); System.out.println(file.getAbsolutePath()); System.out.println( file.getCanonicalPath()); 结果: .\src\test.txt D:\workspace\java_io\.\src\test.txt D:\workspace\java_io\src\test.txt 第二个例子:(使用:...
getCanonicalPath(): 返回的是规范化的绝对路径,相当于将getAbsolutePath()中的“.”和“..”解析成对应的正确的路径 举例如下: File file =newFile(".\\test.txt"); System.out.println(file.getPath()); System.out.println(file.getAbsolutePath()); System.out.println(file.getCanonicalPath()); 返...
If this abstract pathname is already absolute, then the pathname string is simply returned as if by thegetPath()method. If this abstract pathname is the empty abstract pathname then the pathname string of the current user directory, which is named by the system propertyuser.dir, is returned. ...
1、getPath(): 返回定义时的路径,(就是你写什么路径,他就返回什么路径) 2、getAbsolutePath(): 返回绝对路径,但不会处理“.”和“..”的情况 ...

描述java.io.File.getPath()方法将抽象路径名转换为路径名字符串。要按名称顺序分隔名称,结果字符串将使用默认的名称分隔符。 声明 以下是java.io.File.getPath()方法的声明- public String getPath() 参数 不适用 返回值 ...

This is a code snippet to retrieve the path of the current running web application project in java 1 public String getPath() throws UnsupportedEncodingException { 2 String path = this.getClass().getClassLoader().getResource("").getPath(); 3 String fullPath = URLDecoder.decode(path, "UTF...
一个是绝对路径，一个是相对路径 比如说你现在在c:/a/b/下面 有个x.txt new File("x.txt").getPath()有可能得到x.txt getAbsolutePath得到c:/a/b/x.txt
