彈簧引導應用程序在啓動後立即關閉（schedular）

我正在瀏覽彈簧調度程序指南（https://spring.io/guides/gs/scheduling-tasks/），但我的彈簧引導應用程序在啓動後立即終止。我檢查了所有的依賴關係，他們似乎很好。我的輸出是彈簧引導應用程序在啓動後立即關閉（schedular）

我主要的應用程序代碼：

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 

@SpringBootApplication 
public class SpringSchedularApplication { 

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

任我調度文件：

import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
import org.springframework.scheduling.annotation.Scheduled; 
import org.springframework.stereotype.Component; 

import java.text.DateFormat; 
import java.util.Date; 

import static java.text.DateFormat.LONG; 
import static java.text.DateFormat.getDateInstance; 
import static java.util.Locale.US; 

@Component 
public class ScheduledTask { 
    private static final Logger log = LoggerFactory.getLogger(ScheduledTask.class); 
    private static final DateFormat dateFormat = getDateInstance(LONG, US); 

    @Scheduled(fixedRate = 5000) 
    public void readCurrentTime(){ 
     log.info("The time is now[]", dateFormat.format(new Date())); 
    } 
}

將'@ EnableScheduling'添加到您的應用程序類中。 –

@ M.Deinum非常感謝。有效 – Ashish

雖然春季啓動系統能夠大量的東西取決於你的依賴關係對於調度和異步不這樣做。您仍然需要分別通過添加@EnableScheduling和@EnableAsync來手動啓用該功能。

在您的情況下，將@EnableScheduling添加到您的應用程序類就足夠了。

@SpringBootApplication 
@EnableScheduling 
public class SpringSchedularApplication { 

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

有了這個調度將被啓用，因爲有一個調度線程仍在運行應用程序不會關閉。
