• java获得当前文件路径


    第一种:
    File f = new File(this.getClass().getResource("/").getPath());
    System.out.println(f);
    结果:
    C:Documents%20and%20SettingsAdministratorworkspaceprojectNamein
    获取当前类的所在工程路径;
    如果不加“/”
    File f = new File(this.getClass().getResource("").getPath());
    System.out.println(f);
    结果:
    C:Documents%20and%20SettingsAdministratorworkspaceprojectNameincom est
    获取当前类的绝对路径;

    第二种:
    File directory = new File("");//参数为空
    String courseFile = directory.getCanonicalPath() ;
    System.out.println(courseFile);
    结果:
    C:Documents and SettingsAdministratorworkspaceprojectName
    获取当前类的所在工程路径;

    第三种:
    URL xmlpath = this.getClass().getClassLoader().getResource("selected.txt");
    System.out.println(xmlpath);
    结果:
    file:/C:/Documents%20and%20Settings/Administrator/workspace/projectName/bin/selected.txt
    获取当前工程src目录下selected.txt文件的路径

    第四种:
    System.out.println(System.getProperty("user.dir"));
    结果:
    C:Documents and SettingsAdministratorworkspaceprojectName
    获取当前工程路径

    第五种:
    System.out.println( System.getProperty("java.class.path"));
    结果:
    C:Documents and SettingsAdministratorworkspaceprojectNamein
    获取当前工程路径

    通过代码获取jar中的资源,这里就不能path了,要用InputStream:
    InputStream inputStream = this.getClass().getResourceAsStream(fileName);
