基於Activiti5.15.1 自定義用戶、組（User，Group）實現

     本人剛接觸Activiti,最近工作中需要將Activiti中原有的用戶，組（ACT_ID_USER,ACT_ID_GROUP,ACT_ID_MEMBERSHIP）表替換為公司已有的相關表。查看了咖啡兔及論壇相關文章。今天有空整理一下。以幫助后續有此需要的初學者。

 

自定義Group，User工廠類，實現SessionFactory接口

1)CustomGroupEntityManagerFactory

 

@Service
public class CustomGroupEntityManagerFactory implements SessionFactory {

    private CustomGroupEntityManager customGroupEntityManager;

    @Override
    public Class<?> getSessionType() {
　　　　 //注意此處必須為Activiti原生的類，否則自定義類不會生效
        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() {
       //注意此處也必須為Activiti原生類
        return UserIdentityManager.class;
    }

    @Override
    public Session openSession() {
        return customUserEntityManager;
    }

    @Autowired
    public void setCustomUserEntityManager(CustomUserEntityManager customUserEntityManager) {
        this.customUserEntityManager = customUserEntityManager;
    }
}

3)CustomGroupEntityManager

@Component
public class CustomGroupEntityManager extends GroupEntityManager {
    private static final Log logger = LogFactory
            .getLog(CustomGroupEntityManager.class);

    @Autowired
    private UserMapper userMapper;//用於查詢實際業務中用戶表、角色等表


    @Override
    public List<Group> findGroupsByUser(final String userCode) {
        if (userCode == null)
            return null;

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

        List<Group> gs = new java.util.ArrayList<>();
        GroupEntity g;
        String roleId;
        String activitRole;
        for (Role bGroup : bGroupList) {
            g = new GroupEntity();
            g.setRevision(1);
            g.setType("assignment");
            roleId = String.valueOf(bGroup.getRoleID());
            activitRole = bindGroupWithRole.get(roleId);//此處只是根據RoleId獲取RoleCode， 因實際表中無RoleCode字段，暫且如此實際，此行可注釋掉
            g.setId(activitRole != null ? activitRole : roleId);
            g.setName(bGroup.getRoleName());
            gs.add(g);
        }
        return gs;
    }
}

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
