Expose the ClassLoader used by this ResourceLoader. ... Return a Resource handle for the specified resource location. ... Pseudo URL prefix for loading from the class path: "classpath:". ... Return a Resource handle for the specified resource location. The handle should always be a reusable resource descriptor, allowing for multiple InputStreamSource.getInputStream() calls. Must support fully qualified URLs, for example, "file:C:/test.dat".

July 23, 2025 - In Spring, all application contexts implement the ResourceLoader interface. Therefore, all application contexts may be used to obtain Resource instances. Let's see how we can load/read external resources/files by using application context : ... package com.gfg.technicalscripter; 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; public class App { publi

February 26, 2026 - We can also inject the ResourceLoader into our bean with @Autowired: ... Once we have access to the Resource we need to be able to read it into a String. Let’s create a ResourceReader utility class with a static method asString to do this for us. ... Our next step is to take this InputStream and convert it to a String. We can use Spring’s own FileCopyUtils#copyToString method:

December 4, 2023 - Learn different ways to load external resources or files (text files, XML files, properties file, or image files) using Spring ResourceLoader interface.

May 29, 2019 - With the help of Spring application context, we get the ResourceLoaderService object and call the showResourceDataUsingFilePath() using this object. Below is an example which prints the content of loaded resources on the console.

June 23, 2011 - Spring really did a good job with this super generic getResource() method, it really save our time to deal with resources. ... Founder of Mkyong.com, passionate Java and open-source technologies. If you enjoy my tutorials, consider making a donation to these charities. ... Why the workaround with “implements ResourceLoaderAware”? You can instanciate the Springs DefaultResourceLoader and use it directly:

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="resource" class="com.app.javadiscover.ResourceBean" /> </beans> ResourceBean.java · package com.app.javadiscover; import org.springframework.context.ResourceLoaderAware; import org.springframework.core.io.Resource; import org.springframework.core.io.ResourceLoader; public class ResourceBean implements ResourceLoaderAware { private ResourceLoader resourceLoader; public void setResourceLoader(ResourceLoader resourceLoader) { this.resourceLoader = resourceLoader; } public Resource getResource(String location){ return resourceLoader.getResource(location); } } LoadResource.java

March 26, 2025 - Note too that ResourceLoader is implemented by all concrete ApplicationContexts, which means that we can also simply depend on ApplicationContext if that suits our situation better: ApplicationContext context; public Resource loadEmployeesWithApplicationContext() { return context.getResource("classpath:data/employees.dat"); } As a caveat, there is another way to retrieve resources in Spring, but the ResourceUtils Javadoc is clear that the class is mainly for internal use.

August 29, 2019 - With the help of the Spring application context, we get the ResourceLoaderService object and call the showResourceDataUsingFilePath() using this object. Below is an example the prints the content of loaded resources on the console.

All application contexts implement the ResourceLoader interface. Therefore, all application contexts may be used to obtain Resource instances. When you call getResource() on a specific application context, and the location path specified doesn’t have a specific prefix, you get back a Resource type that is appropriate to that particular application context. For example, assume the following snippet of code was executed against a ClassPathXmlApplicationContext instance:

September 4, 2015 - If we want to load a resource from a database table RESOURCE we have to create our own ResourceLoader which triggers on the prefix db:. Let's create an interface which describes the action of getting a resource based on the resourceName. import java.io.InputStream; import org.springframework.core.io.Resource; public interface DatabaseResourceDao { Resource getResource(String resourceName); } In this example our filename is equal to our resourcename.

You can also creating new Spring Boot project using Spring initializr online tool at start.spring.io · Add a new text file to the resources folder named data.txt with content as below for testing purposes. ... Create a new class named TestReadFile and use ResourceLoader class to read data.txt file then log the file content as the following code. ... package dev.simplesolution; import java.io.InputStream; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.CommandLineRunner; import org.springfra

All application contexts implement the ResourceLoader interface, and therefore all application contexts may be used to obtain Resource instances. When you call getResource() on a specific application context, and the location path specified doesn't have a specific prefix, you will get back a Resource type that is appropriate to that particular application context. For example, assume the following snippet of code was executed against a ClassPathXmlApplicationContext instance:

January 31, 2025 - Lastly, we implement the ResourceLoaderAware and ProtocolResolver interfaces with the DatabaseResourceResolver class. This Spring @Component is responsibile for resolve resource locations to DatabaseResource objects, if the resource’s location is well-formatted DatabaseLocation. Spring will automatically call our DatabaseResourceResolver class as resources are injected into Spring applications, loading any DatabaseResource objects as appropriate. package com.example; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.ResourceLoaderAware; import org.

Similar to the previous example, we're prefixing the file path with the resource type - classpath. Then Spring reads the file and returns a Resource instance back. Now, let's access a file on the file system instead of the classpath: final Resource resource = resourceLoader.getResource("fi...

November 28, 2024 - In this example, the ResourceLoader loads the resource from the classpath, and we use a BufferedReader to read its contents. The key point here is the use of the classpath: prefix to indicate that the file is located in the classpath.

August 22, 2025 - ResourceLoader Interface: Used for loading resources in a uniform manner. ApplicationContext: A central interface to provide configuration for an application, which also acts as a resource loader. The Resource interface in Spring is a central interface for accessing various types of resources. Here is an example: // ResourceExample.java package com.example.springresources; import org.springframework.core.io.Resource; import org.springframework.core.io.ResourceLoader; import org.springframework.stereotype.Component; import java.io.BufferedReader; import java.io.InputStreamReader; import java.ut

import org.springframework.core.io.Resource; import org.springframework.core.io.ResourceLoader; ResourceLoader resourceLoader = context; // Use your ApplicationContext Resource resource = resourceLoader.getResource("classpath:example.txt"); // Replace with your resource location · In this example, we're loading a classpath resource named example.txt. You can replace it with your desired resource location. ... To read the contents of the loaded resource as a string, you can use Java I/O operations.

All application contexts implement the ResourceLoader interface. Therefore, all application contexts may be used to obtain Resource instances. When you call getResource() on a specific application context, and the location path specified doesn’t have a specific prefix, you get back a Resource type that is appropriate to that particular application context. For example, assume the following snippet of code was run against a ClassPathXmlApplicationContext instance:
