July 10, 2022
ResourceLoaderAware interface to be implemented by any object that wishes to be notified of the ResourceLoader that it runs in. The ApplicationContext is the sub-interface of ResourceLoader interface. The ResourceLoaderAware is an alternative to a full ApplicationContext dependency via the ApplicationContextAware interface.

EntitlementService.java
package com.concretepage;
import org.springframework.context.ResourceLoaderAware;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
public class EntitlementService implements ResourceLoaderAware {
private ResourceLoader resourceLoader;
public ResourceLoader getResourceLoader() {
return resourceLoader;
}
public void setResourceLoader(ResourceLoader resourceLoader) {
this.resourceLoader = resourceLoader;
}
public Resource getResource(String path) {
return this.getResourceLoader().getResource(path);
}
}
package com.concretepage;
import java.io.IOException;
import java.io.InputStream;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.Resource;
public class SpringDemo {
public static void main(String... args) throws IOException {
ApplicationContext context = new ClassPathXmlApplicationContext("spring-app.xml");
EntitlementService entSer = (EntitlementService)context.getBean("entitlementService");
Resource res = entSer.getResource("concretepage.txt");
InputStream is = res.getInputStream();
try{
int i=0;
while((i=is.read())!=-1)
{
char c=(char)i;
System.out.print(c);
}
}catch(IOException e){
e.printStackTrace();
}finally{
if(is!=null)
is.close();
}
}
