我已经创建了一个Sping Boot 应用程序。我已经配置了包含调度程序方法startService()的类。下面是我的代码：

服务类别：

package com.mk.service;  
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import com.mk.envers.model.BossExtChange;
import com.mk.envers.model.BossExtChangeRepository;

@Component
public class EnverseDemoService {

    @Autowired
    BossExtChangeRepository bossExtChangeRepository;

    @Scheduled(fixedRate = 30000)
    public void startService() {
        System.out.println("Calling startService()");
        BossExtChange bossExtChange = bossExtChangeRepository.findById(5256868L);
        System.out.println("bossExtChange.getDescription()--->"+bossExtChange.getDescription());
        System.out.println("Ending startService()");
    }
}

主类：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.PropertySource;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
@PropertySource("classpath:application.properties")
public class EnverseDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(EnverseDemoApplication.class, args);
    }
}

我已经将类注解为@Component，将作为调度程序运行的方法注解为@Scheduled(fixedRate = 30000)。但是，当作为Sping Boot 运行应用程序时，调度程序不会触发。控制台显示以下消息：

2016-02-03 10:56:47.708  INFO 10136 --- [           main] o.s.j.e.a.AnnotationMBeanExporter        : Registering beans for JMX exposure on startup

2016-02-03 10:56:47.736  INFO 10136 --- [       Thread-2] j.LocalContainerEntityManagerFactoryBean : Closing JPA EntityManagerFactory for persistence unit 'default'

有人能帮帮我吗。
