没有org.springframework.scheduling.concurrent.ConcurrentTaskExecutor类型的限定bean

Question

我有以下课程：

@Component
public class DasServiceHelper {

    @Autowired ConcurrentTaskExecutor executor;


    protected void retrieveDASReferenceData() {

        Callable<List<ReferenceDataType>> callable1 = new Callable<List<ReferenceDataType>>() {
            @Override public List<ReferenceDataType> call() throws Exception {
                //Some method logic
            }
        };

        Callable<List<ReferenceDataType>> callable2 = new Callable<List<ReferenceDataType>>() {
            @Override public List<ReferenceDataType> call() throws Exception {
                //Some method logic
            }
        };

        Callable<List<ReferenceDataType>> callable3 = new Callable<List<ReferenceDataType>>() {
            @Override public List<ReferenceDataType> call() throws Exception {
                //Some method logic
            }
        };

        Callable<List<ReferenceDataType>> callable4 = new Callable<List<ReferenceDataType>>() {
            @Override public List<ReferenceDataType> call() throws Exception {
                //Some method logic
            }
        };

        Future<List<ReferenceDataType>> result1 = executor.submit(callable1);
        Future<List<ReferenceDataType>> result2 = executor.submit(callable2);
        Future<List<ReferenceDataType>> result3 = executor.submit(callable3);
        Future<List<ReferenceDataType>> result4 = executor.submit(callable4);
        Future<List<ReferenceDataType>> result5 = executor.submit(callable5);
    }

这是我的spring配置xml：

<bean name="dasServiceHelper" class="com.nyl.corp.das.DasServiceHelper"/>

<bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ConcurrentTaskExecutor"/>

我正在从我的服务类调用retrieveDASReferenceData()。

编译代码时，我遇到以下异常：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.scheduling.concurrent.ConcurrentTaskExecutor] 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)}
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:967)

    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:486)

知道我在这里缺少什么。

编辑： Spring配置文件：
