Following example shows how to inject ResourceLoader as a bean in our Spring application.

Example

src/main/resources/myFile.txt

this is a my file content.

Injecting ResourceLoader and using it

package com.logicbig.example;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
import org.springframework.stereotype.Component;
import jakarta.annotation.PostConstruct;
import java.io.File;
import java.io.IOException;
import java.nio.file.Files;

@Component
public class ClientBean {
  @Autowired
  private ResourceLoader resourceLoader;

  @PostConstruct
  public void init() throws IOException {
      Resource resource = resourceLoader.getResource("classpath:myFile.txt");
      File file = resource.getFile();
      String s = new String(Files.readAllBytes(file.toPath()));
      System.out.println(s);
  }
}

JavaConfig and main class

package com.logicbig.example;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import java.io.IOException;

@Configuration
@ComponentScan
public class InjectResourceLoaderExample {

  public static void main(String[] args) throws IOException {
      new AnnotationConfigApplicationContext(InjectResourceLoaderExample.class);
  }
}

Output

this is a my file content.
