仿微信运动排行榜的定时任务练习

2018-10-23 本文已影响0人飞逝1

首先，我们先看一下微信运动排行榜的页面以及大致的工作原理。

微信排行榜的每天定时刷新就是定时任务最常用的场景，像我们的微信运动每天晚上大约都是在10点多定时刷新数据。

下面，我将写一个模仿这样的定时任务的例子。

目录结构

目录结构（定时任务）.png

在Config包下新建QuartzConfig,SporterJob,SportJobFactory类

QuartzConfig类

public class QuartzConfig {
    @Autowired
    private SpringJobFactory springJobFactory;

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(){
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        schedulerFactoryBean.setJobFactory(springJobFactory);
        return schedulerFactoryBean;
    }

    @Bean
    public Scheduler scheduler() {
        return schedulerFactoryBean().getScheduler();
    }
}

SporterJob类

@Component
public class SporterJob {

    @Resource
    private UpdateService updateService;

    @Scheduled(cron = "0 26 22 * * ?")
    public void updateTodayWalks() throws Exception {
        updateService.updateWalks();
    }
}

corn里设置刷新时间，corn的用法见我之前的文章。

SporterJobFactory类

@Component
public class SpringJobFactory extends AdaptableJobFactory {
    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;

    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
        Object jobInstance = super.createJobInstance(bundle);
        capableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}

实体类

运动者（Walker）

@Entity
@Data
public class Walker implements Serializable {
    @Id
    @GeneratedValue
    private Integer id;
    private String account;
    private String password;
    private String nickname;
    private String avatar;


    @OneToMany(cascade = CascadeType.ALL,fetch = FetchType.EAGER)
    @JoinColumn(name = "account",referencedColumnName = "account")
    private List<SportData> sportDataList;

    public Walker(String account, String password, String nickname, String avatar, List<SportData> sportDataList) {
        this.account = account;
        this.password = password;
        this.nickname = nickname;
        this.avatar = avatar;
        this.sportDataList = sportDataList;
    }
}

运动数据（SportData）

@Entity
@Data
public class SportData implements Serializable {
    @Id
    @GeneratedValue
    private Integer id;
    private Integer steps;
    private String evaluate;
    private Date date;

    public SportData(Integer steps, String evaluate, Date date) {
        this.steps = steps;
        this.evaluate = evaluate;
        this.date = date;
    }
}

UpdateService类

public interface UpdateService {
    void updateWalks();
}

SportDataRepositry接口


public interface SportDataRepositry extends JpaRepository<SportData,Integer> {
}

实现类（UpdateServiceImpl）

@Service
public class UpdateServiceImpl implements UpdateService {
    @Resource
    private SportDataRepositry sportDataRepositry;

    @Override
    public void updateWalks() {
        List<SportData> list = sportDataRepositry.findAll();
        Random random = new Random();
        for (int i=0;i <list.size();i++) {
            SportData sportData = list.get(i);
            sportData.setSteps(random.nextInt(2000)+2000);
            sportData.setDate(new Date());
            sportDataRepositry.saveAndFlush(sportData);
        }
    }
}
