Injecting a spring bean to a task listener

[romschn]

Hi,

I have a mailBean which is configured as below in a spring context file.

<bean id="mailBean"   class="com.utils.MailBean" >
      <property name="mailService">
          <ref bean="mailService"/>
       </property>
   </bean>‍‍‍‍‍

In my activiti workflow process definition, I am using a task listener class - TestListener extends ScriptTaskListener.

Now, I want to inject the email bean to this listener class. I am not finding any way of doing this.

Could someone please help me on this at the earliest.

Thanks,

Is it something similar to this you are trying to achieve?

Hi Ramesh,

The only way I've found to solve this problem is to manually register your bean in activiti-context.xml by adding new entry to activitiBeanRegistry map as follows:

<util:map id="activitiBeanRegistry" map-class="java.util.HashMap">

        <entry key="services" value-ref="ServiceRegistry" />

    <entry key="SetWorkflowUsers" value-ref="SetWorkflowUsers" /> 

    // In my case SetWorkflowUsers extends ScriptExecutionListener. Also SetWorkflowUsers is my bean id.

 

    </util:map>
‍‍‍‍‍‍‍‍‍‍‍‍

and define your bean as follows:

<bean id="SetWorkflowUsers" class="com.demo.workflow.SetWorkflowUsers">
      <property name="serviceRegistry">
         <ref bean="ServiceRegistry" />
      </property>
      <property name="nodeService">
            <ref bean="NodeService" />
        </property>
        <property name="searchService">
            <ref bean="SearchService"/>
        </property>
   </bean>
and put below entry/method in SetWorkflowUsers.java

/** 
    * 
    * get SetworkflowUsers 's object from Context
    * 
    * */
    protected SetWorkflowUsers getSetWorkflowUsers()
       {
           ProcessEngineConfigurationImpl config = Context.getProcessEngineConfiguration();
           if (config != null) 
           {
               // Fetch the registry that is injected in the activiti spring-configuration
              SetWorkflowUsers setWorkflowUsers = (SetWorkflowUsers) config.getBeans().get("SetWorkflowUsers");
               if (setWorkflowUsers == null)
               {
                   throw new RuntimeException(
                               "setWorkflowUsers not present in ProcessEngineConfiguration beans, expected setWorkflowUsers with key SetWorkflowUsers");
               }
               return setWorkflowUsers;
           }
           throw new IllegalStateException("No ProcessEngineCOnfiguration found in active context");
       }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

So by this way, I can get the object of NodeService, SearchService and ServiceRegistry from my bean SetWorkflowUsers.
Let me know if you need more help.
