Spring ResourceLoaderAware

We use the ResourceLoader when your application object need to access different type of file resources. In this tutorial you will see an example of how to use ResourceLoaderAware interface.

StudentBean.java

package com.roseindia.student.services;

import org.springframework.context.ResourceLoaderAware;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;

public class StudentService implements ResourceLoaderAware {
	private ResourceLoader resourceLoader;

	public void setResourceLoader(ResourceLoader resourceLoader) {
		this.resourceLoader = resourceLoader;
	}

	public Resource getResource(String location) {
		return resourceLoader.getResource(location);
	}
}

AppMain.java

package com.roseindia.common;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.Resource;

import com.roseindia.student.services.StudentService;

public class AppMain {

	public static void main(String[] args) throws Exception {
		ApplicationContext ctx = new ClassPathXmlApplicationContext(
				"context.xml");
		StudentService bean = (StudentService) ctx.getBean("studentBean");

		Resource resource = ctx.getResource("file:c:\\testing.txt");
		try {
			InputStream is = resource.getInputStream();
			BufferedReader br = new BufferedReader(new InputStreamReader(is));

			String line;
			while ((line = br.readLine()) != null) {
				System.out.println(line);
			}
			br.close();

		} catch (IOException e) {
			e.printStackTrace();
		}

	}
}
