我应该将pdf放在Java Web应用程序项目中的哪里？

Question

I have a maven directory structure:

 /src

    /main

        /java 
        /resources 
        /webapp 

So if I put the file under /resources, when I deploy the application to tomcat the file ends up in: webapps/applicationRoot/WEB-INF/classes/xx.pdf

If I put in webapp/ then it ends up in webapps/applicationRoot/xx.pdf

If I create a folder under webapp like webapp/myResources it ends up in: webapps/applicationRoot/myResources/xx.pdf

The 2nd one looks the prettiest I believe because then in the code I can say:

    InputStream is = servletContext.getResourceAsStream("/re.pdf");

How would I get my pdf file in case 1 in my servlet?

Also, which one is the standart? Which should I use?

Answer 1

If you put your pdf under webapp/bla/my.pdf, a user could directly access it in his browser from http://{yoursercer}/{contextroot}/bla/my.pdf. Is that what you want? Put it there then.

If you want the PDF to be accessible to your Java code, then put it under resources. It will not be directly accessible from a browser.

Answer 2

set the content type. response.setContentType("application/pdf");
