Java,jsp,servlet get current project path-absolute path

The relative paths that are called in the JSP and class files are different. In the JSP, the root directory is webroot in the class file, the root directory is webroot/web-inf/classes of course you can also use System.getproperty ("User.dir") to get your project's absolute path.

Another: The way to get the path in detail in Jsp,servlet,java!

Get path in 1.jsp:

Take the project name test as an example:

(1) Get the full path of the current page containing the project name: Request.getrequesturi ()
Results:/test/test.jsp
(2) Get project name: Request.getcontextpath ()
Results:/test
(3) Get the current page in the same directory under the full name: Request.getservletpath ()
Result: If the page is/test/jsp/test.jsp in the JSP directory
(4) Get the full path of the server on which the page is located: Application.getrealpath ("page. JSP")
Results: D:\resin\webapps\TEST\test.jsp
(5) Obtain the absolute path of the server on which the page is located: Abspath=new java.io.File (Application.getrealpath (Request.getrequesturi ())). GetParent ();
Results: D:\resin\webapps\TEST

2. Get the path in the class:

(1) The absolute path of the class: Class.class.getClass (). GetResource ("/"). GetPath ()
Results:/d:/test/webroot/web-inf/classes/pack/
(2) The path to get the project: System.getproperty ("User.dir")
Results: D:\TEST

3. Get the path in the servlet:

(1) Get the Project catalog: Request.getsession (). Getservletcontext (). Getrealpath ("") parameter can be specific to the package name.
Results: E:\Tomcat\webapps\TEST
(2) Get IE Address bar address: Request.getrequesturl ()
Results: Http://localhost:8080/TEST/test
(3) Get relative Address: Request.getrequesturi ()
Results:/test/test
