有一點很重要(這是我放在最前面的原因):調用被@Async註解的方法時,調用方法不能與被調用方法放在同一類中,否則註解不生效
因此,我們應該這樣做:
一個類中實現被調用方法,另一個類進行調用
在啓動類上加@EnableAsync和@EnableScheduling
import com.spring4all.mongodb.EnableMongoPlus;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@EnableAsync
@EnableScheduling
@EnableTransactionManagement(proxyTargetClass = true)
@EnableMongoPlus
@SpringBootApplication
public class MpfcontrolApplication {
public static void main(String[] args) {
// SpringApplication.run(MpfcontrolApplication.class, args);
new SpringApplicationBuilder(MpfcontrolApplication.class).headless(false).run(args);
ViewStart.run();
}
}
使用 @Scheduled(fixedRate=10000)實現定時間間隔調用(單位毫秒)
//定時調用批處理方法
@Scheduled(fixedRate=10000)
public void doTimer(){
// System.out.println("定時執行");
JSONObject json=new JSONObject();
batchAddSystemLog(json,2);
}
