@Autowired - 没有为依赖项找到类型的限定bean

我通过使用Spring和Hibernate为服务创建实体,服务和JUnit测试来启动我的项目.所有这一切都很棒.然后我添加了spring-mvc来使用许多不同的分步教程来创建这个Web应用程序,但是当我尝试使用@Autowired注释创建Controller时,我在部署期间遇到来自Glassfish的错误.我想由于某些原因Spring没有看到我的服务,但经过多次尝试后我仍然无法处理它.

服务测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:/beans.xml"})

和

@Autowired
MailManager mailManager;

工作正常.

没有@Autowired的控制器,我可以毫无困难地在Web浏览器中打开我的项目.

@Controller
@RequestMapping("/")
public class HomeController {

    @Autowired
    public MailManager mailManager;

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String homepage(ModelMap model) {
        return "homepage";
    }

}

错误:

SEVERE:   Exception while loading the app
SEVERE:   Undeployment failed for context /WebMail
SEVERE:   Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'homeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: public pl.com.radzikowski.webmail.service.MailManager pl.com.radzikowski.webmail.controller.HomeController.mailManager; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [pl.com.radzikowski.webmail.service.MailManager] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

很抱歉有很多代码,但我不知道是什么原因造成了这个错误.

添加

我创建了界面:

@Component
public interface IMailManager {

添加工具:

@Component
@Transactional
public class MailManager extends AbstractManager implements IMailManager {

并更改了自动装配:

@Autowired
public IMailManager mailManager;

但它仍然会引发错误(当我尝试使用@Qualifier时)

..不能autowire字段:public pl.com.radzikowski.webmail.service.IMailManager pl.com.radzikowski.webmail.controller.HomeController.mailManager ...

我也试过了@Component和@Transactional的不同组合.

我不应该以某种方式在web.xml中包含beans.xml吗？
