this works fine.

Answer 1

this is a simple example that I have just made:

Main.java

package the.test;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.support.AbstractApplicationContext;

public class Main {

public static void main(String[] args) {

    AbstractApplicationContext aac = new AnnotationConfigApplicationContext(Person.class, Phones.class);
    Person person = aac.getBean(Person.class);
    System.out.println(person.getPhones().getPhoneOne());
    System.out.println(person.getPhones().getPhoneTwo());
    System.out.println(person.getSurname());
    System.out.println(person.getName());
    System.out.println(person.getAge());
    aac.close();

    }
}

Person.java

package the.test;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;

@Configuration

//you may use @ComponentScan("the.test") here and omit declaring 
//"Phone.class" in the main method 

public class Person {
private int age;
private String name;
private String surname;

private Phones phones;

public int getAge() {
    return age;
}
@Value("33")
public void setAge(int age) {
    this.age = age;
}

public String getName() {
    return name;
}

@Value("John")
public void setName(String name) {
    this.name = name;
}

public String getSurname() {
    return surname;
}

@Value("Due")
public void setSurname(String surname) {
    this.surname = surname;
}

public Phones getPhones() {
    return phones;
}
@Resource
public void setPhones(Phones phones) {
    this.phones = phones;
}
}

Phones.java

package the.test;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;

@Configuration
public class Phones {
private String PhoneOne;
private String PhoneTwo;

public String getPhoneOne() {
    return PhoneOne;
}

@Value("987654321")
public void setPhoneOne(String phoneOne) {
    PhoneOne = phoneOne;
}

public String getPhoneTwo() {
    return PhoneTwo;
}

@Value("123456")
public void setPhoneTwo(String phoneTwo) {
    PhoneTwo = phoneTwo;
}

}

this is completely based on Spring Annotation and is made on spring framework 4.2.5

hope it helps.
