java - 无法将 DWR 与 Spring 合并

Question

使用 spring 4.2.0、Dwr 3。使用注解创建所有 Spring Controller 、服务和 daos。工作正常，直到仅在 Spring 环境中。尝试将 DWR 添加为单独的 spring Controller 服务对象不会注入(inject)该 DWR Controller 。使用 NullPointerException 出现以下错误

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)}

下面是代码片段。Dwr Controller 是

@Controller
@RemoteProxy(name = "dwrDemo")
public class DwrDemoController {
@Autowired
private BrandNameService brandNameService;


public void setBrandNameService(BrandNameService brandNameService) {
    this.brandNameService = brandNameService;
}


@RemoteMethod
public List<String> getEmployeeDetails(int id) {
   return brandNameService.getEmployeeDetails(id);
}
:
}

服务类就像

@Service("brandNameService")
@Transactional
public class BrandNameServiceImpl implements BrandNameService{
  public List<String> getEmployeeDetails(int id) {
     return brandNameDAO.getEmployeeDetails(id);
  }
:
}

如果我在 xml 中定义 DWR Controller 并删除 DWR Controller 中的所有注释，则服务器将在不初始化服务对象的情况下启动(此处在调用 dwr 时获取 NullPointerException)下面是 XML

<beans:bean id="dwrDemoController"
    class="com.classified.dwr.controller.DwrDemoController">
    <!-- <beans:property name="brandNameService" ref="brandNameService"/> -->
    <dwr:remote javascript="dwrService">
        <dwr:include method="getEmployeeDetails" />
    </dwr:remote>
</beans:bean>

如果我取消注释brandNameService，tomcat不会启动，启动时出现异常/错误

当我在 applicationContext.xml 而不是 myapp-servlet.xml 中定义所有 bean 时，它就起作用了。
