guava read resources file 2020-02-22 07:21
It is very simple to read files using the tool classes in guava. Here is the example.
public class ReadResourcesFile {
public static void main(String[] args) throws IOException {
URL url = Resources.getResource("test.txt");
String text = Resources.toString(url, StandardCharsets.UTF_8);
System.out.println(text);
}
}
Add a file named test.txt and run the above code you will get the file content in output.
Old version of guava implement Resources.getResource() by using Resource.class.getClassLoader. I use following version
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>23.0</version>
</dependency>
The implement is here.
ClassLoader loader =
MoreObjects.firstNonNull(
Thread.currentThread().getContextClassLoader(), Resources.class.getClassLoader());
