本文主要研究一下PowerJob的UserInfoController

UserInfoController

tech/powerjob/server/web/controller/UserInfoController.java

@RestController
@RequestMapping("/user")
public class UserInfoController {

    @Resource
    private UserService userService;
    @Resource
    private UserInfoRepository userInfoRepository;

    @PostMapping("save")
    public ResultDTO<Void> save(@RequestBody ModifyUserInfoRequest request) {
        UserInfoDO userInfoDO = new UserInfoDO();
        BeanUtils.copyProperties(request, userInfoDO);
        userService.save(userInfoDO);
        return ResultDTO.success(null);
    }

    @GetMapping("list")
    public ResultDTO<List<UserItemVO>> list(@RequestParam(required = false) String name) {

        List<UserInfoDO> result;
        if (StringUtils.isEmpty(name)) {
            result = userInfoRepository.findAll();
        }else {
            result = userInfoRepository.findByUsernameLike("%" + name + "%");
        }
        return ResultDTO.success(convert(result));
    }

    private static List<UserItemVO> convert(List<UserInfoDO> data) {
        if (CollectionUtils.isEmpty(data)) {
            return Lists.newLinkedList();
        }
        return data.stream().map(x -> new UserItemVO(x.getId(), x.getUsername())).collect(Collectors.toList());
    }

    @Getter
    @NoArgsConstructor
    @AllArgsConstructor
    public static final class UserItemVO {
        private Long id;
        private String username;
    }
}

UserInfoController提供了save、list方法，其中save方法用到了userService.save

UserService

tech/powerjob/server/core/service/UserService.java

@Service
public class UserService {

    @Resource
    private UserInfoRepository userInfoRepository;

    /**
     * 保存/修改 用户
     * @param userInfoDO user
     */
    public void save(UserInfoDO userInfoDO) {
        userInfoDO.setGmtCreate(new Date());
        userInfoDO.setGmtModified(userInfoDO.getGmtCreate());
        userInfoRepository.saveAndFlush(userInfoDO);
    }

    /**
     * 根据用户ID字符串获取用户信息详细列表
     * @param userIds 逗号分割的用户ID信息
     * @return 用户信息详细列表
     */
    public List<UserInfoDO> fetchNotifyUserList(String userIds) {
        if (StringUtils.isEmpty(userIds)) {
            return Lists.newLinkedList();
        }
        // 去重
        Set<Long> userIdList = Splitter.on(",").splitToList(userIds).stream().map(Long::valueOf).collect(Collectors.toSet());
        List<UserInfoDO> res = userInfoRepository.findByIdIn(Lists.newLinkedList(userIdList));
        res.forEach(x -> x.setPassword(null));
        return res;
    }
}

UserService提供了save、fetchNotifyUserList方法

alert

tech/powerjob/server/core/instance/InstanceManager.java

    private void alert(Long instanceId, String alertContent) {
        InstanceInfoDO instanceInfo = instanceInfoRepository.findByInstanceId(instanceId);
        JobInfoDO jobInfo;
        try {
            jobInfo = instanceMetadataService.fetchJobInfoByInstanceId(instanceId);
        } catch (Exception e) {
            log.warn("[InstanceManager-{}] can't find jobInfo, alarm failed.", instanceId);
            return;
        }
        JobInstanceAlarm content = new JobInstanceAlarm();
        BeanUtils.copyProperties(jobInfo, content);
        BeanUtils.copyProperties(instanceInfo, content);
        List<UserInfoDO> userList = SpringUtils.getBean(UserService.class).fetchNotifyUserList(jobInfo.getNotifyUserIds());
        if (!StringUtils.isEmpty(alertContent)) {
            content.setResult(alertContent);
        }
        alarmCenter.alarmFailed(content, AlarmUtils.convertUserInfoList2AlarmTargetList(userList));
    }

InstanceManager的alert方法会根据instanceId拉取InstanceInfoDO、JobInfoDO信息，然后根据alertContent创建JobInstanceAlarm，最后通过alarmCenter.alarmFailed(content, AlarmUtils.convertUserInfoList2AlarmTargetList(userList))进行告警；如果用户信息的webHook不为空，则会通过webhook回调；若DingTalkUtils存在且用户信息的phone不为空，则会通过dingTalkUtils.fetchUserIdByMobile(phone)获取dingtalk的userId然后进行dingtalk告警；若javaMailSender实例存在，且配置了from则会通过email进行告警

UserInfoDO

tech/powerjob/server/persistence/remote/model/UserInfoDO.java

@Data
@Entity
@Table(indexes = {
        @Index(name = "uidx01_user_info", columnList = "username"),
        @Index(name = "uidx02_user_info", columnList = "email")
})
public class UserInfoDO {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "native")
    @GenericGenerator(name = "native", strategy = "native")
    private Long id;

    private String username;

    private String password;
    /**
     * 手机号
     */
    private String phone;
    /**
     * 邮箱地址
     */
    private String email;
    /**
     * webHook
     */
    private String webHook;
    /**
     * 扩展字段
     */
    private String extra;

    private Date gmtCreate;

    private Date gmtModified;
}

UserInfoDO定义了id、username、password、phone、email、webHook、extra、gmtCreate、gmtModified属性

相关表

user_info

Create Table: CREATE TABLE `user_info` (
  `id` bigint NOT NULL AUTO_INCREMENT,
  `email` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `extra` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `gmt_create` datetime(6) DEFAULT NULL,
  `gmt_modified` datetime(6) DEFAULT NULL,
  `password` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `phone` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `username` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `web_hook` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `uidx01_user_info` (`username`),
  KEY `uidx02_user_info` (`email`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci
1 row in set (0.00 sec)

这里的user_info仅仅作为任务告警用

job_info

CREATE TABLE `job_info` (
  `id` bigint NOT NULL AUTO_INCREMENT,
  `alarm_config` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `app_id` bigint DEFAULT NULL,

  `gmt_modified` datetime(6) DEFAULT NULL,
  `instance_retry_num` int DEFAULT NULL,
  `instance_time_limit` bigint DEFAULT NULL,
  `job_description` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `job_name` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `job_params` longtext COLLATE utf8mb4_general_ci,

  `min_disk_space` double NOT NULL,
  `min_memory_space` double NOT NULL,
  `next_trigger_time` bigint DEFAULT NULL,
  `notify_user_ids` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `processor_info` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `processor_type` int DEFAULT NULL,
  `status` int DEFAULT NULL,
  `tag` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `task_retry_num` int DEFAULT NULL,
  `time_expression` varchar(255) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `time_expression_type` int DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `idx01_job_info` (`app_id`,`status`,`time_expression_type`,`next_trigger_time`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci

job_info定义了notify_user_ids字段，存储了任务要告警的用户的id，多个用逗号分隔

小结

PowerJob的UserInfoController提供了save、list方法，其中save方法用到了userService.save；UserService提供了save、fetchNotifyUserList方法；它的userInfo仅仅是作为job的告警用户，其中job_info定义了notify_user_ids字段，存储了任务要告警的用户的id，多个用逗号分隔；InstanceManager的alert方法会根据instanceId拉取InstanceInfoDO、JobInfoDO信息，然后根据alertContent创建JobInstanceAlarm，最后通过alarmCenter.alarmFailed(content, AlarmUtils.convertUserInfoList2AlarmTargetList(userList))进行告警。
