springboot线程池

1.创建类

@Configuration
public class ThreadPoolConfig {
    @Bean
    public ExecutorService getThreadPool(){
        return Executors.newFixedThreadPool(20);
    }
}

2.

Future<String> updateFuture = executorService.submit(new updateCallable(personBindPowerTemp,this,this.loginUserHolder.getLoginUser().getUsername()));

class updateCallable implements Callable<String>{
    private PersonBindPower personBindPower;
    private IPersonBindPowerService iPersonBindPowerService;
    private  String username;

    public updateCallable(PersonBindPower personBindPower, IPersonBindPowerService iPersonBindPowerService,String username) {
        this.personBindPower = personBindPower;
        this.iPersonBindPowerService = iPersonBindPowerService;
        this.username = username;
    }

    @Override
    public String call() throws Exception {

        iPersonBindPowerService.updateThread(personBindPower,username);
        return "批量更新门禁线程执行结束"+personBindPower.getPersonId()+personBindPower.getDeviceId();
    }
}

注意的是：开启的多线程是session是null，获取不到登录信息。用到登录信息，在用之前登录
