Java获取工程路径的几种方法
第一种:
1 File f = new File(this.getClass().getResource("/").getPath()); 2 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“/”:
1 File f = new File(this.getClass().getResource("").getPath()); 2 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
1 File directory = new File("");//参数为空 2 String courseFile = directory.getCanonicalPath() ; 3 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
1 URL xmlpath = this.getClass().getClassLoader().getResource("selected.txt"); 2 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
1 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
1 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
