簡單配置

1. 不用匯入其他依賴，只需要在啟動類上加入@EnableScheduling註解，啟動對定時任務的支援
2. 編寫非同步任務配置類，使用@EnableAsync啟用對非同步任務的支援，@Configuration表示該類為配置類
3. 具體類

@Configuration
@EnableAsync
public class AsyncTaskConfig {

    @Value("${task.async.pool.corePoolSize}")
    int corePoolSize;
    @Value("${task.async.pool.maxPoolSize}"
 
)
    int maxPoolSize;
    @Value("${task.async.pool.queueCapacity}")
    int queueCapacity;
    @Bean
    public Executor taskExecutor(){

        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(corePoolSize);
        executor.setMaxPoolSize(maxPoolSize);
        executor.setQueueCapacity(queueCapacity);
        executor.initialize();
        return
 
 executor;

    }
}

關於配置檔案資訊

#非同步任務執行緒池配置
task.async.pool.corePoolSize=10
task.async.pool.maxPoolSize=200
task.async.pool.queueCapacity=10

4. 建立任務類

@Component
public class AsyncTaskDemo {

    @Async
    @Scheduled(cron = "0/2 * * * * *")
    public void task(){
        System.out.println(this.hashCode());
    }
}
