基于Activiti5.15.1 自定义用户、组（User，Group）实现

     本人刚接触Activiti,最近工作中需要将Activiti中原有的用户，组（ACT_ID_USER,ACT_ID_GROUP,ACT_ID_MEMBERSHIP）表替换为公司已有的相关表。查看了咖啡兔及论坛相关文章。今天有空整理一下。以帮助后续有此需要的初学者。

 

自定义Group，User工厂类，实现SessionFactory接口

1)CustomGroupEntityManagerFactory

 

@Service

public class CustomGroupEntityManagerFactory implements SessionFactory {



    private CustomGroupEntityManager customGroupEntityManager;



    @Override

    public Class<?> getSessionType() {

　　　　 //注意此处必须为Activiti原生的类，否则自定义类不会生效

        return GroupIdentityManager.class;

    }



    @Override

    public Session openSession() {

        return customGroupEntityManager;

    }



    @Autowired

    public void setCustomGroupEntityManager(CustomGroupEntityManager customGroupEntityManager) {

        this.customGroupEntityManager = customGroupEntityManager;

    }

}

 

2)CustomUserEntityManagerFactory

@Service

public class CustomUserEntityManagerFactory implements SessionFactory {



    private CustomUserEntityManager customUserEntityManager;



    @Override

    public Class<?> getSessionType() {

       //注意此处也必须为Activiti原生类

        return UserIdentityManager.class;

    }



    @Override

    public Session openSession() {

        return customUserEntityManager;

    }



    @Autowired

    public void setCustomUserEntityManager(CustomUserEntityManager customUserEntityManager) {

        this.customUserEntityManager = customUserEntityManager;

    }

}

3)CustomGroupEntityManager

 1 @Component

 2 public class CustomGroupEntityManager extends GroupEntityManager {

 3     private static final Log logger = LogFactory

 4             .getLog(CustomGroupEntityManager.class);

 5 

 6     @Autowired

 7     private UserMapper userMapper;//用于查询实际业务中用户表、角色等表

 8 

 9 

10     @Override

11     public List<Group> findGroupsByUser(final String userCode) {

12         if (userCode == null)

13             return null;

14 

15         List<Role> bGroupList = userMapper.getGroupByUserName(userCode);

16 

17         List<Group> gs = new java.util.ArrayList<>();

18         GroupEntity g;

19         String roleId;

20         String activitRole;

21         for (Role bGroup : bGroupList) {

22             g = new GroupEntity();

23             g.setRevision(1);

24             g.setType("assignment");

25             roleId = String.valueOf(bGroup.getRoleID());

26             activitRole = bindGroupWithRole.get(roleId);//此处只是根据RoleId获取RoleCode， 因实际表中无RoleCode字段，暂且如此实际，此行可注释掉

27             g.setId(activitRole != null ? activitRole : roleId);

28             g.setName(bGroup.getRoleName());

29             gs.add(g);

30         }

31         return gs;

32     }

33 }

4)CustomUserEntityManagerFactory

@Component

public class CustomUserEntityManager extends UserEntityManager {

    private static final Log logger = LogFactory.getLog(CustomUserEntityManager.class);



    @Autowired

    private UserMapper userMapper;



    @Override

    public UserEntity findUserById(String userId) {

        UserEntity userEntity = new UserEntity();

        com.jimubox.transformers.model.user.User cue = userMapper.getUserByUserName(userId);

        ActivitiUtils.toActivitiUser(cue);

        return userEntity;

    }



    @Override

    public List<Group> findGroupsByUser(final String userCode) {

        if (userCode == null)

            return null;



        List<String> groupIds = userMapper.getGroupIdsByUserName(userCode);



        List<Group> gs = null;

        gs = Utils.toActivitiGroups(groupIds);

        return gs;



    }



  

}

5）applicationContext.xml
