使用定时任务中ScheduledExecutorService实现步数统计
- 添加完整poml依赖
- 创建两个类，sport和walker
sport
@Entity
@Data
public class Sport {
@Id
@GeneratedValue
private Integer id;
private String account;
private Integer stepNumbers;
public Sport(String account, Integer stepNumbers) {
this.account = account;
this.stepNumbers = stepNumbers;
}
public Sport() {
}
}
walker
@Data
public class Walker {
@Id
@GeneratedValue
private Integer id;
private String account;
private String password;
private String nickname;
private String avatar;
public Walker(String account, String password, String nickname, String avatar) {
this.account = account;
this.password = password;
this.nickname = nickname;
this.avatar = avatar;
}
public Walker() {
}
}
- 添加repository类
sportrepository
public interface SportRepository extends JpaRepository<Sport, Integer> {
@Query(" from Sport order by stepNumbers desc ")
List<Sport> getAll();
Sport findSportByAccount(String account);
}
walkersportrepository
public interface WalkRepository extends JpaRepository<Walker, Integer> {
Walker findByAccountAndPassword(String account, String password);
Walker findByAccount(String account);
}
- 添加定时任务job
@Component
public class Jobs {
@Resource
private SportRepository sportRepository;
public static List<Sport> rankingList = null;
@Scheduled(cron = "0 48 21 * * ?")
public void ranking() {
rankingList = sportRepository.getAll();
System.out.println(rankingList);
}
public List<Sport> rank() {
return rankingList;
}
}
- 添加controller类
@Controller
@RequestMapping(value = "/user")
public class WalkController {
@Resource
private WalkRepository walkRepository;
@Resource
private SportRepository sportRepository;
private Walker walker = new Walker();
private Sport sport = new Sport();
private Jobs jobs = new Jobs();
@RequestMapping("/login")
public String login(HttpServletRequest request, HttpSession session) {
String username = request.getParameter("username");
String password = request.getParameter("password");
walker = walkRepository.findByAccountAndPassword(username, password);
sport = sportRepository.findSportByAccount(username);
String str = "";
if (walker != null) {
session.setAttribute("userLogin", walker);
session.setAttribute("steps", sport);
session.setAttribute("ranking", jobs.rank());
str = "home";
} else {
str = "index";
}
return str;
}
}
- 最后添加页面
