how to connect parent-xml and child-xml in spring

I want to know how to connect(reference) parent-xml and child-xml in spring.

I have two xml which one is context.xml(parent-xml) and the other is contextSub.xml(child-xml). Also, I have one test class.

What I want is that without writing setup() method, how to connect(or reference) two xml(parent-xml and child-xml)?

In setup() method, there are some logic(cording) to make context.xml child-xml connect(to connect context.xml and child-xml). But I think there is another way to connect them. Alredy, I tried that I wrote 

import resource="classpath:/test/src/main/resources/context.xml"

in contextSub.xml, but it didn't work. Could you please let me know? Is there any wrong cording?

*******context.xml *******

<?xml version="1.0" encoding="UTF-8"?>

http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="hello" class="com.nana.service.Hello">
    <property name="name" >
        <value>HongSangJik</value>
    </property>
    <property name="printer" ref="consolePrint" />
</bean>

<bean id="consolePrint" class="com.nana.service.ConsolePrinter" />

****** contextSub.xml ******

<?xml version="1.0" encoding="UTF-8"?>

http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="helloSub" class="com.nana.service.Hello">
    <property name="name">
        <value>HongGilDong</value>
    </property>
    <property name="printer" ref="consolePrint" />
</bean>

******** HelloTest.java ********

 package com.nana.service;

    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations="/context.xml")

    public class HelloTest {
    ApplicationContext context;
    ApplicationContext subContext;
    Hello hello;
    Hello hellosub;

    @Before
    public void setup() {
        context= 
                new GenericXmlApplicationContext("/context.xml");
        hello = context.getBean("hello", Hello.class);
        GenericApplicationContext child= 
                new GenericApplicationContext(context);
        XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(child);
        reader.loadBeanDefinitions("contextSub.xml");
        child.refresh();
        hellosub=child.getBean("helloSub", Hello.class);
    }

    @Test
    public void sayHelloTest() {
        assertThat("Hello!HongSangJik", is(hello.sayHello()));
        assertThat("Hello!HongGilDong", is(hellosub.sayHello()));

    }
}

---------------After updating setup() code [HelloTest]

package com.nana.service;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="/context.xml")


public class HelloTest {
ApplicationContext context;
ApplicationContext subContext;
Hello hello;
Hello hellosub;

@Before
public void setup() {

    context= new GenericXmlApplicationContext("/context.xml");
    hello = context.getBean("hello", Hello.class);
    hellosub=context.getBean("helloSub", Hello.class);

}

@Test
public void sayHelloTest() {
    assertThat("Hello!HongSangJik", is(hello.sayHello()));
    assertThat("Hello!HongGilDong", is(hellosub.sayHello()));

}

}

****[context.xml]****

<?xml version="1.0" encoding="UTF-8"?>

http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="helloSub" class="com.nana.service.Hello">
    <property name="name">
        <value>HongGilDong</value>
    </property>
    <property name="printer" ref="consolePrint" />
</bean>

Since your context.xml is parent-xml and contextSub.xml is child-xml, I would try adding this line to context.xml:

<import resource="contextSub.xml"/>

and remove the <import....> from contextSub.xml file.

In the java code we only need to load "context.xml" file.

@Before
public void setup()
{
    context= new GenericXmlApplicationContext("/context.xml");
    hello = context.getBean("hello", Hello.class);
    hellosub=context.getBean("helloSub", Hello.class);
}
