lockStore in RunAs context

vincent-kali — Mon, 04 Aug 2014 21:09:26 GMT

Hi I'm trying to develop a Web Script to lock/unlock contents on behalfof different users. To do this, I first tried to execute LockStore methodsin 'RunAs' mode. After reading the code I discovered that LockStore methodsare using FullyAuthenticatedUser instead of RunAsUser.Then I started to develop

Hi,
I think the only way to do that (using RunAs user in LockStore 'set' method) is to override the spring beans
of lockStore.
Could somebody confirm that ?
I just don't know how to do that. Could somebody help me ?
Some examples ?

Thanks,
Vincent

Hi
Some updates regarding my issue above:
I'm now trying to override the 'org.alfresco.repo.lock.mem' package with 'org.alfresco.repo.lock.mem.ks2',
to make use of RunAs user in code.

I put the following declaration in module-context.xml file


   <bean id="lockStoreFactory" class="org.alfresco.repo.lock.mem.ks2.DefaultLockStoreFactory"/>
    <bean id="lockStore" factory-bean="lockStoreFactory" factory-method="createLockStore"/>
    <bean id="lockableAspectInterceptor" class="org.alfresco.repo.lock.mem.ks2.LockableAspectInterceptor">
        <property name="nodeService" ref="mlAwareNodeService"/>
        <property name="lockStore" ref="lockStore"/>
        <property name="authenticationService" ref="authenticationService"/>
    </bean>
‍‍‍‍‍‍‍‍‍

And I get the following error at startup:

      
Error creating bean with name 'org.springframework.aop.framework.ProxyFactoryBean#250ee2f3': FactoryBean threw exception
on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'lockableAspectInterceptor' defined in class path resource [alfresco/core-services-context.xml]: Initialization of bean failed;
nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type
'org.alfresco.repo.lock.mem.ks2.LockStoreImpl' to required type 'org.alfresco.repo.lock.mem.LockStore' for property 'lockStore';
nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.alfresco.repo.lock.mem.ks2.LockStoreImpl]
to required type [org.alfresco.repo.lock.mem.LockStore] for property 'lockStore': no matching editors or conversion strategy found
‍‍‍‍‍‍‍‍‍

I just don't know how to proceed…..
One simple question: is it just possible to override LockService/LockStore ?
If yes, please advice.

Thanks,
Vincent

Why are you trying to use the lock store directly? What's wrong with the Lock Service?

I want to lock/unlock nodes on behalf of other users.
When dealing with EPHEMERAL locks (which is my case) LockService is calling LockStore to get/set LockState from/to memory.
As LockState is using the FullyAuthenticatedUser, I can't set a LockState to renew a lock or unlock a node already locked.
This is my problem. That's why I want to modify the setLockState method to allow impersonate using RunAs user.
I'm now trying to override the corresponding class (LockStoreImpl), and package as an AMP module..
Do you thing it's would be a "correct" way to proceed ?

Thanks,
Vincent
