Question

我一直试图在Spring中使用@Resource和@Service注释，如下所示。

这是我的服务类

@Service("personService")
public class PersonService {
    protected static Logger logger = Logger.getLogger("PersonService");
    // service methods here
}

我的控制器课程在这里

@Controller
public class PersonController {

    protected static Logger logger = Logger.getLogger("controller");

    @Resource(name="personService")
    private PersonService personService;

    // controller methods
}

当我在jboss服务器上部署此应用程序时，我收到以下错误。

当我不使用这些注释时，应用程序可以正常运行。

Answer 1

是否与此有关应用程序上下文中的<context:annotation-config/>或<context:component-scan> xml？

Answer 2

异常是java.lang.ClassNotFoundException: com.demoApp.service.PersonService这意味着问题不在于注入不起作用，而是因为找不到PersonService类。

您应该检查它是否正确部署（类和注释）。并且您使用了正确的注释（例如，导入了正确的Service类，而不是像org.my.strange.project.Service那样）

在Spring中使用@Resource和@Service注释时出错
