关于获取路径path

String webPath = request.getServletPath();

log.info(webPath);

输出：

/zjdlbb/zjdlbb/zjdlbb/test.ht

log.info(request.getServletContext().getRealPath("/"));

输出：

E:\Program Files (x86)\workspace\oms\web\

String webPath = request.getContextPath();

log.info(webPath);

输出：/oms

// 使用相对目录的方式读取文件，相对目录即是项目的目录

File file = new File("src" + File.separator + "dom"

+ File.separator + "xml" + File.separator + "class.xml");

File file2 = new File(DomDemo.class.getClassLoader()

.getResource("").getPath().substring(1)

+ "dom"

+ File.separator

+ "xml"

+ File.separator

+ "class.xml");

//当前路径

System.out.println(Demo01.class.getResource("."));//   file:/D:/Program/workspace/freemarker/WebRoot/WEB-INF/classes/demo01/

System.out.println(Demo01.class.getResource(""));//    file:/D:/Program/workspace/freemarker/WebRoot/WEB-INF/classes/demo01/
