java.net.URL getResource(java.lang.String path) throws java.net.MalformedURLException Returns a URL to the resource that is mapped to a specified path. The path must begin with a “/” and is interpreted as relative to the current context root. This method allows the servlet container to ...

2、通过CLASSPATH读取包内文件 读取包内文件,使用的路径一定是相对的classpath路径,比如a,位于包内,此时可以创建读取a的字节流: InputStream in = ReadFile.class.getResourceAsStream("/com/lavasoft/res/a.txt"); 有了字节流,就能读取到文件内容了。
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...
String currentPath=request.getRequestURI();String queryString="?param1=value1¶m2=value2";String fullPath=currentPath+queryString; 路径在Web应用中的常见应用 HTTP响应路径在Web应用程序中有许多常见的应用,以下是一些示例: 链接到其他页面 在网页上,你可以使用路径来链接到其他页面。例如,你可以创建一个超...
Path relative = Paths.get("myprog","conf","user.properties"); 静态的Paths.get方法接受一个或多个字符串,并将它们用默认的文件系统路径分隔符(/,\)连接起来,然后解析连接起来的结果,如果表示的不是给定文件系统的合法路径,就抛出InvalidPathException异常。这个连接起来的结果就是一个Path对象。
String path = "/var/data/stuff/xyz.dat";String base = "/var/data";String relative = new File(base).toURI(). relativize(new File(path).toURI()).getPath();// relative == "stuff/xyz.dat"请注意,对于文件路径,...
