在Spring Boot集成Activiti时，可以使用自定义用户及用户组表与Activiti的IdentityService进行关联。

下面是一个简单的代码示例来实现这个过程：

1.创建User和Group类：

public class ActivitiUser implements User {
        
        private String id;
        private String firstName;
        private String lastName;
        private String email;
        private String password;
    
        // Getters and Setters
    }

public class ActivitiGroup implements Group {
        
        private String id;
        private String name;
        private String type;
    
        // Getters and Setters
    }

2.创建ActivitiUserServiceImpl类实现自定义用户服务：

@Service
    public class ActivitiUserServiceImpl implements UserDetailsService {
        
        @Autowired
        private UserRepository userRepository;
    
        @Override
        public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        
            ActivitiUser user = userRepository.findByUsername(username);
    
            if (user == null) {
        
                throw new UsernameNotFoundException(username);
            }
    
            return user;
        }
    }

3.创建ActivitiGroupServiceImpl类实现自定义用户组服务：

@Service
    public class ActivitiGroupServiceImpl implements GroupManager {
        
        @Autowired
        private GroupRepository groupRepository;
    
        @Override
        public List<Group> findGroupsByUser(String userId) {
        
            List<ActivitiGroup> groups = groupRepository.findGroupsByUserId(userId);
            return new ArrayList<>(groups);
        }
    
        @Override
        public List<Group> findGroupsByNativeQuery(Map<String, Object> parameterMap, int firstResult, int maxResults) {
        
            throw new UnsupportedOperationException();
        }
    
        @Override
        public long findGroupCountByNativeQuery(Map<String, Object> parameterMap) {
        
            throw new UnsupportedOperationException();
        }
    }

4.使用自定义用户和用户组服务配置Activiti的身份认证：

@Configuration
    public class ActivitiConfig {
        
        @Autowired
        private UserDetailsService userDetailsService;
        @Autowired
        private GroupManager groupManager;
    
        @Bean
        public ProcessEngineConfigurationConfigurer engineConfigurationConfigurer() {
        
            return engineConfiguration -> {
        
                engineConfiguration.setUserEntityManager(new ActivitiUserEntityManager(userDetailsService));
                engineConfiguration.setGroupEntityManager(new ActivitiGroupEntityManager(groupManager));
            };
        }
    }

这样，Spring Boot框架中的用户信息就与Activiti的用户组信息建立了关联。
