Unclear how to configure activiti about spring-boot-with-activiti-example HOT 16 CLOSED

@HarisHashim: what an amount of text above here ;-) I'm trying to reconstruct ... do you have a repo with the code in I can take a look at?

These lines:

CustomUserEntityManagerFactory userEntityManagerFactory = new CustomUserEntityManagerFactory();
CustomGroupEntityManagerFactory groupEntityManagerFactory = new CustomGroupEntityManagerFactory();

    sessionFactories.put(CustomUserEntityManager.class, userEntityManagerFactory);
    sessionFactories.put(CustomGroupEntityManager.class, groupEntityManagerFactory);

should indeed do it.

(For future reference: I added a simpler way to do the above in the current master: https://github.com/Activiti/Activiti/blob/master/modules/activiti-spring-boot/spring-boot-starters/activiti-spring-boot-starter-basic/src/main/java/org/activiti/spring/boot/ProcessEngineConfigurationConfigurer.java)

from spring-boot-with-activiti-example.

@z772458549 ,
i use spring boot, the final config like below.
`@Configuration
@AutoConfigureBefore(org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration.class)
public class ActivitiConfiguration implements ProcessEngineConfigurationConfigurer {

@Resource(name = "myGroupManagerFactory")
private SessionFactory groupManagerFactory;

@Resource(name = "myUserManagerFactory")
private SessionFactory userManagerFactory;

public void configure(SpringProcessEngineConfiguration pec) {
    // 权限设置
    pec.setDbIdentityUsed(false);   // 禁用activiti默认的权限表
    // 替换activiti的默认权限功能
    List<SessionFactory> customSessionFactories = new ArrayList<SessionFactory>();
    customSessionFactories.add(userManagerFactory);
    customSessionFactories.add(groupManagerFactory);
    if (pec.getCustomSessionFactories() == null){
        pec.setCustomSessionFactories(customSessionFactories);
    }
    else{
        pec.getCustomSessionFactories().addAll(customSessionFactories);
    }
}

}`

The regular Spring way: have a @configuration class and inject the ProcessEngine or ProcessEngineConfiguration bean that is created by Spring Boot.

Alternatively, you can also define the engine/config bean yourself and Spring Boot won't instantiate it for you (at least, that's how I remember it)

Thanks.

Hello there, I am trying to do the same. Since I am new to Spring Boot and Activiti, don't really understaood what is meant by

"The regular Spring way: have a @configuration class and inject the ProcessEngine or ProcessEngineConfiguration bean that is created by Spring Boot."

I have (blindly) tried with bellow codes. And get errors (attached at the end). Appreciate anyhelp!

TIA
Haris

@Configuration
public class ProcessEngineConfig {

    @Autowired
    private ProcessEngineConfiguration processEngineConfiguration;

    @Autowired 
    private CustomUserEntityManagerFactory userEntityManagerFactory;

    @Autowired
    private CustomGroupEntityManagerFactory groupEntityManagerFactory;


    public void configure() {
        Map<Class<?>, SessionFactory> sessionFactories = ((ProcessEngineConfigurationImpl) processEngineConfiguration)
                .getSessionFactories();

        sessionFactories.put(CustomUserEntityManager.class, userEntityManagerFactory);
        sessionFactories.put(CustomGroupEntityManager.class, groupEntityManagerFactory);

        ProcessEngine engine = processEngineConfiguration.buildProcessEngine();

        ProcessEngines.registerProcessEngine(engine);
        ProcessEngines.init();
    }
}

But I am getting bellow errors

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngineConfig': Injection of autowired dependencies failed;

My bad!

Removed @Autowired from the two custom factory

    //@Autowired 
    private CustomUserEntityManagerFactory userEntityManagerFactory;

    //@Autowired
    private CustomGroupEntityManagerFactory groupEntityManagerFactory;

Now it builds and run but the configure() function was never run. So obviously this is wrong way to do it.

To be honest I dont understand what is meant by

"The regular Spring way: have a @configuration class and inject the ProcessEngine or ProcessEngineConfiguration bean that is created by Spring Boot."

I tried initializing using constructor and then call configure().

public ProcessEngineConfig() {
        userEntityManagerFactory =  new CustomUserEntityManagerFactory();
        groupEntityManagerFactory = new CustomGroupEntityManagerFactory();

        configure();
    }

This give me

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.activiti.ProcessEngineConfig$$EnhancerBySpringCGLIB$$99c4af75]: Constructor threw exception; nested exception is java.lang.NullPointerException

i.e. the injected processEngineConfiguration is actually null.

So again appreciate help. @jbarrez

This code build and run without run time error.

Have not tested it to know whether it actually work yet.

@Configuration
public class ActivitiConfig {

    @Bean
    public ProcessEngine processEngine(ProcessEngineConfigurationImpl pec, ApplicationContext applicationContext) throws Exception {
        ProcessEngineFactoryBean pe = new ProcessEngineFactoryBean();
        pe.setProcessEngineConfiguration(pec);
        pe.setApplicationContext(applicationContext);

        return pe.getObject();
    }

    @Primary
    @Bean
    public ProcessEngineConfigurationImpl getProcessEngineConfiguration(
            DataSource dataSource,
            PlatformTransactionManager transactionManager,
            ApplicationContext context) {
        SpringProcessEngineConfiguration pec = new SpringProcessEngineConfiguration();

        pec.setDataSource(dataSource); 
        pec.setDatabaseSchemaUpdate("true");
        pec.setJobExecutorActivate(true);
        pec.setHistory("full");
        pec.setMailServerPort(2025);
        pec.setDatabaseType("h2");


        pec.setTransactionManager(transactionManager);
        pec.setApplicationContext(context);

        Map<Class<?>, SessionFactory> sessionFactories = new HashMap<Class<?>, SessionFactory>();

        CustomUserEntityManagerFactory userEntityManagerFactory =  new CustomUserEntityManagerFactory();
        CustomGroupEntityManagerFactory groupEntityManagerFactory = new CustomGroupEntityManagerFactory();

        sessionFactories.put(CustomUserEntityManager.class, userEntityManagerFactory);
        sessionFactories.put(CustomGroupEntityManager.class, groupEntityManagerFactory);

        pec.setSessionFactories(sessionFactories);

        return pec;
    }

    @Bean
    public RuntimeService getRuntimeService(ProcessEngine processEngine) {
        return processEngine.getRuntimeService();
    }

}

To some extent I know that above code works. For instance during first test, there is a runtime error but the app keeps running.

They are several errors telling me that during startup the app can not insert stuff into act_id_group table. I double check with previous database and it shows that, indeed some group are created and inserted into that table. This group are created on the fly when process is read into the system. This is indeed true, since I have a process diagram that I assign some task/process to several groups.

Fixing that error in the custom group code, I no longer see same error when running the app. So my conclussion, I fix the error! However, at the same time I did not see the same groups mentioned above being created in act_id_group or my custom group_data table.

I am writing this for the benefit of the next person who discover this thread. If there is answer, that will help a lot. Otherwise, will just keep banging my head on the wall hopping to find solution.

Cheers!

Nah ... it does not work. In fact I begin to question whether this custom user and group will work at all.

For instant, instead of above codes. This time around I did XML configuration as in mondhs solution. And make sure that piece of XML beans configuration is read by spring.

Then I make sure this piece of code from this activiti-spring-boot repo is executed

    @Bean
    InitializingBean usersAndGroupsInitializer(
            final IdentityService identityService) {

        final Logger log = LoggerFactory.getLogger(this.getClass());

        return new InitializingBean() {
            public void afterPropertiesSet() throws Exception {

                Group group = identityService.newGroup("user");
                group.setName("users");
                group.setType("security-role");
                identityService.saveGroup(group);

                User admin = identityService.newUser("rootadmin");
                admin.setPassword("admin");
                identityService.saveUser(admin);

            }
        };
    }

My finding is that IdentityService still use the act_id_user and act_id_group table. Instead of my custom table. Concluding that Identity Service is still not using my customized user and group factory/manager.

Does this means problem with my code or the engine will not use my custom user and group table and I have to manually do stuff like creating group whenever the engine read diagram with group set?

With that said, I still did not see group created in act_id_group or my own custom table when diagram is read by the engine. So I am still thinking that I have not done this right. But kinda hard to not do it right when it is just XML configuration that I am sure is being read and configured by spring.

from spring-boot-with-activiti-example.

use your above code, i also can't not use custom GroupManager & UserManager, can you please give a doucument for it.

from spring-boot-with-activiti-example.

i used version 5.17

from spring-boot-with-activiti-example.

my code is below:
@component(value="myGroupManagerFactory")
public class ActivitiGroupManagerFactory implements SessionFactory {
@Autowired
private TGroupRepository groupDao;

@Override
public Class<?> getSessionType() {
    return GroupIdentityManager.class;
}

@Override
public Session openSession() {
    return new ActivitiGroupManager(groupDao);
}

}

@component(value = "myUserManagerFactory")
public class ActivitiUserManagerFactory implements SessionFactory {
@Autowired
private TUserRepository userDao;

@Override
public Class<?> getSessionType() {
    return UserIdentityManager.class;
}

@Override
public Session openSession() {
    return new ActivitiUserManager(userDao);
}

}

@configuration
public class ActivitiConfiguration {
@resource(name = "myGroupManagerFactory")
private SessionFactory groupManagerFactory;

@Resource(name = "myUserManagerFactory")
private SessionFactory userManagerFactory;

@Bean
Object getProcessEngineConfigurationConfigurer(SpringProcessEngineConfiguration pec) {
    new ProcessEngineConfigurationConfigurerImpl().configure(pec);
    return null;
}

class ProcessEngineConfigurationConfigurerImpl implements ProcessEngineConfigurationConfigurer {
    public void configure(SpringProcessEngineConfiguration pec) {
        SessionFactory[] factories = new SessionFactory[] { groupManagerFactory, userManagerFactory };
        pec.setCustomSessionFactories(Arrays.asList(factories));
        // Map<Class<?>, SessionFactory> sessionFactories = new
        // HashMap<Class<?>, SessionFactory>();
        //
        // sessionFactories.put(ActivitiUserManagerFactory.class,
        // userManagerFactory);
        // sessionFactories.put(ActivitiGroupManagerFactory.class,
        // groupManagerFactory);
        //
        // pec.setSessionFactories(sessionFactories);
    }
}

}

from spring-boot-with-activiti-example.

finally, replace these code will be ok.

class ProcessEngineConfigurationConfigurerImpl implements ProcessEngineConfigurationConfigurer {
public void configure(SpringProcessEngineConfiguration pec) {
// SessionFactory[] factories = new SessionFactory[] { groupManagerFactory, userManagerFactory };
// pec.setCustomSessionFactories(Arrays.asList(factories));

        Map<Class<?>, SessionFactory> sessionFactories = pec.getSessionFactories();
        sessionFactories.put(userManagerFactory.getSessionType(), userManagerFactory);
        sessionFactories.put(groupManagerFactory.getSessionType(), groupManagerFactory);

        pec.setSessionFactories(sessionFactories);
    }
}

@sendreams I follow your step,it does't work, can you put your whole code.

Hello @jbarrez,
Could you please check this related question Configure Activiti to reuse the existing user/group data in Spring Boot

Thank you.
