獲取當前類的所在工程路徑; 如果不加“/” File f = new File(this.getClass().getResource("").getPath()); System.out.println(f); 結果:C:\Documents%20and%20Settings\Administrator\workspace\projectName\bin\com\test 獲取當前類的絕對路徑; 第二種:File directory = new File("");//參數為空 String courseFile = directory.getCanonicalPath() ; System.out.println(courseFile); 結果:C:\Documents and Settings\Administrator\workspace\projectName 獲取當前類的所在工程路徑; 第三種:URL xmlpath = this.getClass().getClassLoader().getResource("selected.txt"); System.out.println(xmlpath); 結果:file:/C:/Documents%20and%20Settings/Administrator/workspace/projectName/bin/selected.txt 獲取當前工程src目錄下selected.txt文件的路徑 第四種:System.out.println(System.getProperty("user.dir")); 結果:C:\Documents and Settings\Administrator\workspace\projectName 獲取當前工程路徑第五種:System.out.println( System.getProperty("java.class.path")); 結果:C:\Documents and Settings\Administrator\workspace\projectName\bin 獲取當前工程路徑
