java中獲取工程中res目錄路徑的方法？

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%20SettingsAdministratorworkspaceprojectNameincom est 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 SettingsAdministratorworkspaceprojectName 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 SettingsAdministratorworkspaceprojectName 獲取當前工程路徑第五種：System.out.println( System.getProperty("java.class.path"))

;結果：C:Documents and SettingsAdministratorworkspaceprojectNamein獲取當前工程路徑
