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
