从Java中的src / main / resources访问静态文件

Question

In my SpringBoot project I would like to read an image file located in:

I tried:

URL url = getClass().getResource("android.png");
File f = new File(url.getPath());

and:

URL url = getClass().getResource("static/images/android.png");
File f = new File(url.getPath());

but the result is null.

EDIT: this worked

try {
   File file = new ClassPathResource("static/images/android.png").getFile();    
} catch (IOException e) {

}

Answer 1

如果您使用的是Spring，则最好使用内置的ClassPathResource类来访问类路径中的文件。

Answer 2

You can try this

File file = new ClassPathResource("/images/android.png").getFile();

because we can access static folder from anywhere

Answer 3

你有没有尝试过

ClassLoader.getSystemResourceAsStream("/static/images/android.png");

Answer 4

you can use this.getClass().getResource("/static/images").getFile(); to get the folder location and then append with the file name to get the file location.

Example

String path=this.getClass().getResource("/static/images").getFile();
File File f = new File(path+"/​android.png");
