Question

我尝试使用Spring管理的服务通过Restful Web-Service发送电子邮件。但是，我检索以下异常：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'messsageservice' is defined
    org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:698)
    org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1175)
    org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:284)
    org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:197)
    org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:956)
    com.hope.mobilehope.controller.Authcodegen.getactivationkey(Authcodegen.java:26)

代码：

@Service("messsageservice")

public class Messsageservice {


    @Autowired
    private MailSender mailSender;
    public void sendMail(String from, String to, String subject, String body) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(body);
        mailSender.send(message);           
    }                       
}        

@RestController    
public class Authcodegen {  

 @RequestMapping(value = "/activationkeygenerator", method = RequestMethod.GET,headers="Accept=application/json")
 public Authcode getactivationkey( @RequestParam(value="email") String name){
     Authcode authcode = new Authcode();
     Random rnd = new Random();
     ApplicationContext context = new FileSystemXmlApplicationContext("**/springrest-servlet.xml");
     Messsageservice msgservice = (Messsageservice) context.getBean("messsageservice");
     String to_email=name;
     int n = 100000 + rnd.nextInt(900000);
     String code=String.valueOf(n);
     msgservice.sendMail("ethonnoreply@gmail.com", to_email, "authcode", code);
     authcode.setId(n);
     authcode.setStatus("Sucess");
 return authcode;

  }       
}

的pom.xml
