CGLIB is required to process @Configuration classes


Incase if you are using @Configuration annotation to create java based configuration as shown below:

@Configuration
public class MyAppConfig {

    @Bean(name="helloBean")
    public HelloWorld helloWorld()
    {
        return new HelloWorldImpl();
    }
}

And if you are getting below exception, then check your maven dependencies and make sure you have added cglib dependencies in your pom.xml.

Exception in thread "main" java.lang.IllegalStateException: CGLIB is required to process 
@Configuration classes. Either add CGLIB to the classpath or remove the following 
@Configuration bean definitions: [appConfig]

If not, add below dependency in your pom.xml file, which will solve your problem.

		<dependency>
			<groupId>cglib</groupId>
			<artifactId>cglib</artifactId>
			<version>3.0</version>
		</dependency>

Where can we use serialization?
Whenever an object has to sent over the network, those objects should be serialized. Also if the state of an object is to be saved, objects need to be serilazed.
