java获得当前文件路径

it2025-01-17  20

第一种: File f = new File(this.getClass().getResource("/").getPath()); System.out.println(f); 结果: C:\Documents%20and%20Settings\Administrator\workspace\projectName\bin 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%20Settings\Administrator\workspace\projectName\bin\com\test 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 Settings\Administrator\workspace\projectName 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 Settings\Administrator\workspace\projectName 获取当前工程路径

第五种: System.out.println( System.getProperty("java.class.path")); 结果: C:\Documents and Settings\Administrator\workspace\projectName\bin 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);
