没有限定型豆类型exchecutorService | Taskscheduler

Question

在这里是调度配置

@Configuration
@EnableScheduling
public class RWInventorySchedule {

protected org.slf4j.Logger log = LoggerFactory.getLogger(RWInventorySchedule.class);

@PersistenceContext
private EntityManager entityManager;


   @Bean
   public RWInventoryProcessor constructInventoryProcessor() {
       log.debug("RWInventorySchedule constructs InventoryProcessor, entityManager : {} " , entityManager);
       return new RWInventoryProcessor(entityManager);
    }
}

inventory处理器是以下

public class RWInventoryProcessor  {
 ...
 @Scheduled(fixedRate = 5000,initialDelay = 3000)
 @Transactional
 public void runProcess() {
   ...
 }
}

执行，在调试日志中获取以下错误

depebug org.springframework.scheduling.annotation.scheduledannotationbeanbeanpostProcessor - 找不到默认任务Cheduler bean org.springframework.beans.factory.nosuchbeandefinitionException：否 'org.springframework.scheduling.taskscheduler'的合格豆 可用的

...

debug org.springframework.scheduling.annotation.scheduledannotationbeanpostprocessor - 找不到默认的speculedexecutorService bean org.springframework.beans.factory.nosuchbeandefinitionException：否 合格的豆类 'Java.util.concurrent.scheduledexecutorservice'可用

我错过了任何东西

如果您使用的是Java配置，则需要用于使用的调度程序类型的@BEAN定义。 Spring对此没有默认的bean。例如

@Bean
public TaskScheduler taskScheduler() {
    return new ConcurrentTaskScheduler(); //single threaded by default
}

Answer 1

我已经使用了此表格我的XML弹簧配置：

<task:annotation-driven  executor="executor" />

<task:scheduler id="scheduler" pool-size="10"/>

<task:executor id="executor" pool-size="7"/>

我的组件处理器是：

Answer 2

@Component
public class QueueConsumer {

    @Autowired
    ProcessQueue queue;

    @Autowired
    TaskProcessor processor;

    @Autowired
    TaskResultRepository resultRepository;

    @Scheduled(fixedDelay = 15000)
    public void runJob() {
        ProcessTask task = queue.poll();
        ...
    }
}

您需要等效于

<task:scheduler id="scheduler" pool-size="10"/>的注释
