Cannot load configuration class

I am following this tutorial about how to use Spring and based on the provided example, I get the following exception:

Exception in thread "main" java.lang.IllegalStateException: Cannot load configuration class: com.tutorialspoint.HelloWorldConfig

I have researched my problem and have found this; someone also has had the same problem as me, and it has something to do with ensuring that ASM is compatible with CGLIB. However I have tried this solution and it has not worked, I even went as far as using the exact same versions as the one provided (GBLIB 2.2.2 and ASM 3.3.1).

What do I need to do in order to correct this?

For simplicity, here are the files which I am using that were extracted from the provided tutorial.

HelloWorldConfig.java

package com.tutorialspoint;
import org.springframework.context.annotation.*;

@Configuration
public class HelloWorldConfig {

    @Bean
    public HelloWorld helloWorld() {
        return new HelloWorld();
    }
}

HelloWorld.java

package com.tutorialspoint;

public class HelloWorld {
    private String message;

    public void setMessage(String message) {
        this.message = message;
    }

    public void getMessage() {
        System.out.println("Your Message : " + message);
    }
}

MainApp.java

package com.tutorialspoint;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.*;

public class MainApp {
    public static void main(String[] args) {
        @SuppressWarnings("resource")
        ApplicationContext ctx = new AnnotationConfigApplicationContext(
                HelloWorldConfig.class);

        HelloWorld helloWorld = ctx.getBean(HelloWorld.class);

        helloWorld.setMessage("Hello World!");
        helloWorld.getMessage();
    }
}

Also by saying 'However I have tried this solution and it has not worked' I mean that the exact same error is returned.

I too encountered the same problem. I tried working with different versions. But same error occured when I used versions below 5.1.0.RELEASE... But It is working fine for all the versions from 5.1.0.RELEASE

Sample code:

 <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.1.0.RELEASE</version>
    </dependency>

Check out the POM.xml for suitable dependencies enter image description here and also JRE as well... it will work with java 1.7

Gone through this problem yesterday and Here is the solution.

  1. Open Eclipse
  2. Open window in menu bar -> preferences -> java ->installed jre
  3. add new jre which is installed in system(c:program_files->java->jre->bin) add it.
  4. Select the new added jre and BOOOM 🔥🔥

I had the same problem and realized the JRE version I have in the POM.xml or the default one associated with the project was not set in the class path. So updated the same under Preferences -> Installed JREs and ran the application it worked.

This problem occurred due to spring dependency problem, I too used below dependency facing same issue, the configuration classes didn't loaded

    <!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.1.6.RELEASE</version>
</dependency>

Try below one: for me it is working 

    <!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.1.6.RELEASE</version>
</dependency>

All jars required for this project to run:
1) org.springframework.core-3.0.1.RELEASE-A.jar
2) spring-context-3.0.4.RELEASE.jar
3) org.springframework.beans-3.0.1.RELEASE-A.jar
4) commons-logging-1.1.1.jar
5) asm-3.3.1.jar
6) cglib-2.2.2.jar

To get these jars,either add the downloaded jars to your project directly, or provide the following dependencies in the pom.xml to get them automatically downloaded for you.

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>3.0.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>3.0.1.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.1.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>3.0.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>cglib</groupId>
            <artifactId>cglib</artifactId>
            <version>2.2.2</version>
        </dependency>
    </dependencies>

Add this to your maven settings.xml file if not already present:

    <profiles>
        <profile>
            <id>SPRINGLEARN</id>
            <activation>
                <jdk>1.8</jdk>
            </activation>
            <repositories>
                <repository>
                    <id>thirdPartyRepo</id>
                    <name>Third party repository</name>
                    <url>https://repo.spring.io/libs-release/</url>
                    <layout>default</layout>
                    <snapshotPolicy>always</snapshotPolicy>
                </repository>
            </repositories>
            <pluginRepositories>
                <pluginRepository>
                    <id>thirdPartyPluginRepo</id>
                    <name>Third party plugin repository</name>
                    <url>https://repo.spring.io/libs-release/</url>
                    <layout>default</layout>
                    <snapshotPolicy>always</snapshotPolicy>
                </pluginRepository>
            </pluginRepositories>
        </profile>
    </profiles>

After this, just run your project.
-Right click on your project -> Run as -> Maven clean
-Right click on your project -> Run as -> Maven install
-Right click on your project -> Run as -> Java application

So, i would say the "other" you mentioned, has an different problem.
Even when the "Last-Shown-Exception" is the same as yours.
But as you can see in your stacktrace, the "source" is a SecurityException.

The *Cannot load configuration class*-Error is a aftereffect

I assume there is something wrong with the "code signation" in your project
or, due to ByteCode-Manipulation, the signation is broken.

PS:
Sometimes this also can happen, when you reference "SignedLibs" and "UnsignedLibs" in your project.
in this case remove the signation from the signed libs.
