Moh*_*mar 11 java scheduler spring-boot
我创建了一个Spring Boot应用程序.我已经配置了包含调度程序方法的类startService().以下是我的代码:
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()");
}
}

我已经注释了类@Component和方法,@Scheduled(fixedRate = 30000)因为它将作为调度程序运行.但是在将应用程序作为Spring Boot运行时,调度程序不会触发.控制台显示以下消息:

可能是您可以通过在配置文件中添加@ComponentScan批注来解决此问题
@SpringBootApplication
@EnableScheduling
@ComponentScan(basePackages = "com.mk.service")
@PropertySource("classpath:application.properties")
public class EnverseDemoApplication {
public static void main(String[] args) {
SpringApplication.run(EnverseDemoApplication.class, args);
}
}

一定是您忘记在您的应用程序类中添加 @EnableScheduling 注释。
public static void main(String[] args) {
context = SpringApplication.run(YouApplication.class, args);
}

我终于能够解决上述问题,我改变了我的服务类的包EnverseDemoService从package com.mk.service;到 com.mk.envers.service;.这是因为如果主要配置类EnverseDemoApplication存在于包中com.mk.envers.引导应用程序中的所有其他类应该在合格包中.Eg: com.mk.envers.*;

我能解决问题,我忘记提供@service level annotation,我已经为@Scheduler创建了检查列表,请一一检查每一点,它会帮助您解决问题。
随意在评论中添加更多点,以便它有助于解决问题。
