在spring中为@scheduled注释添加调度程序而不使用xml注释

Answer 1

可以使用java配置来完成。但不使用注释属性。

您可以查看Spring API文档中的一些扩展示例。

例如：

 @Configuration
 @EnableScheduling
 public class AppConfig implements SchedulingConfigurer {

     @Override
     public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
         taskRegistrar.setScheduler(taskScheduler());
     }

     @Bean(destroyMethod="shutdown")
     public Executor taskScheduler() {
         return Executors.newScheduledThreadPool(42);
     }

 }

 @Configuration
 @EnableScheduling
 public class AppConfig implements SchedulingConfigurer {

     [...]

     @Bean(destroyMethod="shutdown", name = "taskSchedulerA")
     public Executor taskSchedulerA() {
         return Executors.newScheduledThreadPool(42);
     }
     @Bean(destroyMethod="shutdown", name = "taskSchedulerB")
     public Executor taskSchedulerA() {
         return Executors.newScheduledThreadPool(42);
     }
 }


 @Service
 public class MyService {
      @Autowired @Qualifier("taskSchedulerA")
      private Executor taskSchedulerA; 
      @Autowired @Qualifier("taskSchedulerB")
      private Executor taskSchedulerB; 

      @PostConstruct
      public void schedule(){
        Executors.newScheduledThreadPool(42).schedule(new Runnable() {
          @Override
          public void run() {
            functionOfGroupA();
          }
    } , ..);

      }
 }
