Read file from /src/main/resources/

问题

I am trying to do a web application and have a problem: I don't know how to open a text file with Java that is saved in the resource folder:

 String relativeWebPath ="/src/main/resources/words.txt";  //Import der des Textdoumentes
 String absoluteDiskPath = getServletContext().getRealPath(relativeWebPath);
 File f = new File(absoluteDiskPath);

(The file words.txt)

As you can see on the image I am trying to access words.txt but it isn't working. Any ideas?

回答1:

Try this.

InputStream is = getClass().getClassLoader()
                         .getResourceAsStream("/words.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(is));

回答2:

For best practice, and avoid these problems, put text file (words.txt) to WEB_INF folder (this is secure folder for resources). Then:

ServletContext context = getContext();
InputStream resourceContent = context.getResourceAsStream("/WEB-INF/words.txt");

Use this code to find the path to the file you want to open.

import java.net.URL;

[...]

URL url = this.getClass().getResource("/words.txt");
String absoluteDiskPath = url.getPath();
