Question

I am using Spring, i am not using JSF, using ajax etc.

I have a service

@Service(value="mailService")
public class MailService{
//an autowired dao, etc here
}

I have a bean, i want this bean have one MailService.

//Here i have tried so far individually @Service, @Component, @Controller
public class EmailAgent{

private MailService mailService;



    public MailService getMailService() {
        return mailService;
    }

    @Autowired
    public void setMailService(MailService mailService) {
        this.mailService = mailService;
    }

}

I have below in applicationContext.xml

<context:component-scan base-package="mypack.containing.emailagent.path.too" />
<context:annotation-config/>

mailService in EmailAgent is null on calling one EmailAgent method.

I request some advise, and i want to understand why i do not get any exception during server starting up, like, “i could not autowire mailService”. Awhile ago i was using JSF and i was be able to see such warning while server start up.

PROBLEM IS SPECIFIED, HOW TO SOLVE

i was generating ea with EmailAgent ea=new EmailAgent();
It is my sillyness but,
when i try to get one context like:

ClassPathXmlApplicationContext cont=new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
                  mailService=()cont.getBean("mailService");

i am faced with the problem non unique cache etc, problems about generating one more context.
So how can i “get” context, preventing “generating” one more?

SOLVED

I added

<bean class="email.EmailService" id="emailService"> 
  <dwr:remote javascript="emailService"> 
    <dwr:include method="sendMail"/>
    <dwr:include method="readAllMails"/>
    <dwr:include method="removeMailsById"/> 
  </dwr:remote> 
</bean> 

to dwr.xml and deleted annotation from emailService about dwr.

dwr s and spring s annotations were really conflicting as i can see.

Thanks to @NimChimpsky for idea on detecting the problem.

Answer 1

You don’t need another context, unless you are integration testing.

Where is emailagent being used ? Just inject it as normal there. As you do with mailservice.

You can annotate it with Component or Service, both are appropriate.
