我使用的是带有JBoss服务器7.1的SpringFramework3.2。我试图用jpa2(Hibernate Provider，MySQL)和Spring MVC创建一个简单的Spring应用程序。
我使用一个简单的DAO，并将其与自动生成的注解一起注入到主控制器中。这个Dao类只有一个字段(Em)来注入sistentContext，它再简单不过了，我不使用Persistence.xml，因为3.1版和更高版本的Spring不需要一个.....请注意，包是正确扫描的，我已经尝试了Web上发布的其他解决方案中的所有方法(包括这里)...但我得到了这样的错误：
Org.springframework.beans.factory.BeanCreationException：无法自动布线字段：com.stko.home.Model.daos.UserDao com.stko.home.controllers.HomeController.userDao；嵌套异常为org.springframework.beans.factory.BeanCreationException：错误，创建名为“”UserDao“”的Bean时出错：注入持久化依赖项失败；嵌套异常为org.springframework.beans.factory.NoSuchBeanDefinitionException：未定义类型为[org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:514)org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:87)org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:285)org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1120).持久性.实体管理器工厂]的唯一Bean：应为单个Bean，但找到0：Java org.springFrawork.Beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:522)org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:461)org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:295)org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:223)org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:292)org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:194)org.springFramework.Beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:607)org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:932)org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:479)org.springframework.web.servlet.FrameworkServlet.configureAndRefreshWebApplicationContext(FrameworkServlet.java:647)org.springframework.web.servlet.FrameworkServlet.createWebApplicationContext(FrameworkServlet.java:598)org.springframework.web.servlet.FrameworkServlet.createWebApplicationContext(FrameworkServlet.java:661)org.springframework.web.servlet.FrameworkServlet.initWebApplicationContext(FrameworkServlet.java：517)org.springframework.web.servlet.FrameworkServlet.initServletBean(FrameworkServlet.java:458)org.springframework.web.servlet.HttpServletBean.init(HttpServletBean.java:138)javax.servlet.GenericServlet.init(GenericServlet.java:242)org.jboss.as.jpa.interceptor.WebNonTxEmCloserValve.invoke(WebNonTxEmCloserValve.java:50)org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:153)org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)org.apache.Catalina.Connector.CoyoteAdapter服务(CoyoteAdapter.Java：368)org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877)org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:671)org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930)的java.lang.Thread.run(线程.

我的用户Dao：

@Service("userDao")
@Repository
public class UserDao implements Serializable {
  @PersistenceContext
  private EntityManager em;

  @Transactional
  public  void saveUser(User user) {
  if(user!=null)
   em.persist(user);
  }

}

我的实体类用户：

@Entity
   @Table(name = "user")
   public class User implements Serializable {

   @Id
   @GeneratedValue(strategy = GenerationType.IDENTITY)
   @Column(name = "userid")
   private Integer userid;

   @Column(name="username")
   private String username;
   public User(){}
   }

我的典型家庭控制器是：

@Controller
public class HomeController {
.....

@Autowired
UserDao userDao;

@RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {

.....

User newUser = new User();
newUser.setName("blabla");

userDao.saveUser(newUser);

return "home";
} 

}
