Spring auto-wire dependency which has constructor argument

I have my mailing service with has constructor argument and implements an interface

public class MailServiceImpl implements MailService {
    private MailBo mail;

    public MailBO getMail() {
        return Mail;
    }

    public void setMail(MailBO Mail) {
        this.Mail = Mail;
    }

    public MailServiceImpl(MailBo mail) {
        throw exception if from and to address is not here
        this.mail = mail;
    }

    public void sendMail(){
        use mail object to send mail here
    }
}

so now i am trying to write a test which i want to create Mailserviceimpl instance autowired with constructor argument passed in it.

i followed this link to autowire object with constructor, but i am getting below exception 

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.model.MailBO] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

my test class

public class MailServiceImplTest {


    @Autowired
    private MailService mailServiceImpl;

    @Test
    public void testSendValidMail(){
    //test
    }
}

EDIT:-

adding spring context 

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.service" />



</beans>

EDIT 2:- i want my mailbo loaded with some values and inject as constructor object to mailserviceimpl

I assume that MailServiceImpl and MailBO are Spring Beans. Then just annotate MailServiceImpl constructor by @Autowired and Spring will automatically injects constructor dependency
