本文主要研究一下PowerJob的UserInfoController
UserInfoController
tech/powerjob/server/web/controller/UserInfoController.java
代码语言：javascript复制@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
代码语言：javascript复制@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
代码语言：javascript复制 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
代码语言：javascript复制@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

user_info
代码语言：javascript复制Create Table: CREATE TABLE `user_info` (
`id` bigint NOT NULL AUTO_INCREMENT,

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。
