The following app-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:annotation-config/>

<bean id="profile" class="com.skills421.spring15.beans.Profile"/>

<bean id="student1" class="com.skills421.spring15.beans.Student"
p:name="John Doe"
p:age="21"/>

<bean id="student2" class="com.skills421.spring15.beans.Student"
p:name="Jane Doe"
p:age="19"/>

</beans>

can be replaced with the following SpringConfig.java

package com.skills421.spring16.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.skills421.spring16.beans.Profile;
import com.skills421.spring16.beans.Student;

@Configuration
public class SpringConfig
{
@Bean
public Profile profile()
{
return new Profile();
}

@Bean
public Student student1()
{
return new Student("James Davinson", 30);
}

@Bean
public Student student2()
{
return new Student("Nicky Taylor", 19);
}
}

The MainApp.java code needs to be modified as follows:

AbstractApplicationContext ctx = new AnnotationConfigApplicationContext(SpringConfig.class);
ctx.registerShutdownHook();

Profile profile = (Profile) ctx.getBean("profile");

profile.printName();
profile.printAge();

You will also need the CGLib jar

This can be added in the Pom as follows:

<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>2.2.2</version>
</dependency>

or downloaded from cglib.sourceforge.net
