Java 自动连接具有@Configuration@EnableScheduling@component注释的bean组件时出错

我在sprig应用程序中工作 它们有一个类scheduledJob，具有以下注释

@Configuration
@EnableScheduling
@Component 
public class ScheduledJob {
//code
}

我需要将此自动连接到另一个类notificationServiceImpl。我给

@Service
public class NotificationServiceImp implements NotificationService{
  @Autowired
  private ScheduledJob scheduledJob;
//code

}

我得到以下错误

我刚到春天。请帮我解决这个问题

编辑 计划类函数在计划时间内工作正常。没有发现任何问题。但我当前的需求是添加一个选项，以使用API调用触发此函数。因此，我可以启动一个新触发器，通过发送此API调用随时发送通知

我曾尝试在没有自动布线的情况下创建新对象（我知道这不是一个好方法）

调用内部函数，如

scheduledJob.function（）

---

计划类函数在计划时间内工作正常。函数在计划时间内运行时未发现异常或任何内容。如果通过API调用函数，则在调用该函数中的其他java对象时，会发生一些空指针异常。我认为其他自动连线对象此时可能未初始化

我认为您使用@Configuration注释的方式有问题。 我想在您的情况下，实现应该如下所示：

@Configuration
@EnableScheduling
public class AppConfig {
    @Bean
    public Task task() {
        return new Task();
    }
} 

@Configuration只负责bean的创建。如果您以前使用过xml驱动的配置，它就是xml bean定义的替代品。在上面的示例中，它创建了一个可以在应用程序中自动连接的bean

计划bean的实际实现可以定义如下：

public class Task {
    @Scheduled(fixedRate=2000)
    public void doTask(){
        System.out.println("do some task");
    }
} 

---

这确实给了您实现的灵活性。

不确定您是否可以在没有@Bean注释的情况下使用配置！！！它可以完美地运行所有类，唯一的问题是在自动连接类scheduledJob时发生。这些类使用其他类与其他类的自动关联，没有任何问题。

public class Task {
    @Scheduled(fixedRate=2000)
    public void doTask(){
        System.out.println("do some task");
    }
}
