IdentitySession in Activiti 5.5

zeroone — Mon, 02 May 2011 14:02:05 GMT

Hey,I wanted to integrate Spring Security into Activit's IdentitySession, but I was uanble to find the IdentitySession-Interface.Could It be, that it is no longer available under the FQN: org.activiti.engine.impl.cfg.IdentitySession?Ciao,Christoph

Hi,

The persistence internals have been renamed a bit. Look for UserManager and GroupManager now…

Thanks found it.

Since a lot of people have been asking on how to integrate their own user/group tables, would it be fair to ask for this to be included in the manual even with an EXPERIMENTAL tag ? I had just about puzzled the IdentitySession integration together from the forums, and now it has been renamed/split into UserManager and GroupManager. This is bound to throw off many forum searches.

You can always start with writing a page that can be in the wiki or something… so feel free to write down what you did and how you achieved things… 🙂

Hi there,

I implemented custom identity session with Spring Security using the approach discuss here http://forums.activiti.org/en/viewtopic.php?f=6&t=1261

As IdentitySession is interface, where GroupManager and UserManager are concrete class. How do I implement the custom identity service in Activiti 5.5?

Lastly, in my opinion, it was more to major refactoring instead of minor renaming.

Please advice. Thanks.

Best regards,

Anyone? This issue was blocking the release of Grails Activiti Plugin 5.5.

Hi all,

How do I implement the custom identity service in Activiti 5.5?

Because I also have the requirement to acces an LDAP, I've written two classes extending GroupManager and UserManager respective. Before creating the process engine, I have put the two classes as managers into the configuration:


Map<Class<?>,SessionFactory> facts = ((ProcessEngineConfigurationImpl)config).getSessionFactories();
            
facts.put( GroupManager.class, new org.activiti.engine.impl.persistence.GenericManagerFactory( LDAPGroupManager.class ) );
facts.put( UserManager .class, new org.activiti.engine.impl.persistence.GenericManagerFactory( LDAPUserManager .class ) );

My problem is, that after the Password is accepted, and the user group "admin" is succesfully delivered, the logon fails with the following error appearing on the browser:


HTTP ERROR: 500
Request processing failed; nested exception is org.springframework.extensions.surf.exception.UserFactoryException: Unable to retrieve user from repository
RequestURI=/activiti-probe/service/

Which methods are required at minimum in these two classes. Are there another manager required to implement?

Hi all,

We desperately need an answer to Chee Kin's question (see above).

what I did is to add this to "processEngineConfiguration" config in spring,

<property name="customSessionFactories">
   <list>
    <bean class="com.xxxxx.user.ActivitiCustomUserManagerFactory">
     <property name="usersDao" ref="usersDAO"/>
    </bean>
   </list>
</property>

And this factory will return ActivitiCustomUserManager (extends UserManager) in its openSession() method.

Similar thing should be needed for GroupManager and its Factory as well.

I tried the following configuration:

<bean class="org.grails.activiti.springsecurity.SpringSecurityUserManagerFactory">
<property name="usersDao" ref="usersDAO"/>
</bean>
<bean class="org.grails.activiti.springsecurity.SpringSecurityGroupManagerFactory">
<property name="groupsDao" ref="groupsDAO"/>
</bean>
</list>
</property>

and SpringSecurityUserManagerFactory implementation:


package org.grails.activiti.springsecurity;

import org.activiti.engine.impl.interceptor.Session;
import org.activiti.engine.impl.interceptor.SessionFactory;

class SpringSecurityUserManagerFactory implements SessionFactory {
 public Class<?> getSessionType() {
  return UserManager.class;
 }

 public Session openSession() {
  return new UserManager();
 }
}

Unluckily, the code above doesn't work, did I overlook anything?

Please advice.

I managed to make it work by doing what you did:


public Class<?> getSessionType() {
      return UserManager.class;
   }

   public Session openSession() {
      return new MyUserManager();
   }

Notice the MyUserManager()

At the activity repository one can find a test that shows how to replace the IdentitySession. However that code doesn't work anymore in activiti 5.5 as mention here.

It would be nice to know if the way to replace the IdentitySession/UserManager will change in the future. I understand that activiti is currently under development but I think it is important to know if which APIs are stable besides the public APIs. Unfortunately there is no documentation about it (or at least I could not find it).

What error did you see? In your config, the factory has DAO reference, how come there is not such property in your actual class?

Thanks.

Thanks for writing. It is copy and paste mistake. I basically set up the Spring application context using Spring DSL in Grails. The corrected code (my application don't need DAOs) below is for illustration only:


<property name="customSessionFactories">
<list>
  <bean class="org.grails.activiti.springsecurity.SpringSecurityUserManagerFactory" />
  <bean class="org.grails.activiti.springsecurity.SpringSecurityGroupManagerFactory" />
</list>
</property>

Hi there,

When I boot up my application, I find out that the activiti engine invokes getSessionType() of SpringSecurityUserManagerFactory and SpringSecurityGroupManagerFactory, but not openSession().

Below is the way I implement the UserManager, may I know is there anything wrong?


package org.grails.activiti.springsecurity
…

class UserManager extends org.activiti.engine.impl.persistence.entity.UserManager {
…
}

Please see a complete source code here http://code.google.com/p/grails-activiti-spring-security-plugin/source/browse/src/groovy/org/grails/activiti/springsecurity/UserManager.groovy

I'd love to hear from you about how to troubleshooting this problem.

Best regards,
Chee Kin

Hi ageen and Carlos,

I still have no idea what went wrong.

Would you mind to share the code of UserManagerFactory and UserManager implementation?

Thanks,
Chee Kin

Re: IdentitySession in Activiti 5.5

ageen — Fri, 13 May 2011 01:33:55 GMT

In this case, I would suggest you to pull out the activiti source code (specifically the engine module and the spring module, or maybe webapp-rest code as well), to debug it and see what's going on. That's what I would do if see something similar.

Sure. Thanks for quick response.

Anything wrong with my implementation of UserManager class?

<property name="customSessionFactories"> <list> <bean class="org.grails.activiti.springsecurity.SpringSecurityUserManagerFactory"> <property name="usersDao" ref="usersDAO"/> </bean> <bean class="org.grails.activiti.springsecurity.SpringSecurityGroupManagerFactory"> <property name="groupsDao" ref="groupsDAO"/> </bean> </list> </property>and SpringSecurityUserManagerFactory implementation:
package org.grails.activiti.springsecurity; import org.activiti.engine.impl.interceptor.Session; import org.activiti.engine.impl.interceptor.SessionFactory; class SpringSecurityUserManagerFactory implements SessionFactory { public Class<?> getSessionType() { return UserManager.class; } public Session openSession() { return new UserManager(); } }I guess you should return org.activiti.engine.impl.persistence.entity.UserManager instead of the one in package org.grails.activiti.springsecurity. In this way, the custom SessionFactory can override original UserManager settings.

+1 on Auzreal's point.
