Service bean call inside a script task

[d.cherkasov (Dmitry Cherkasov)]

Hello!

Right now, we using flowable engine for BPM, so this is more easy to do

1. Define Spring Bean in spring boot app:

   @Component("BaseBean")
   public class baseBean {
       public String doSomething() {
           System.out.println("do something");
           return "Do something";
       }
   }
   

2. Use this bean inside script task. Bean name has to be matched with its name in spring context:

   res = BaseBean.doSomething();
   execution.setVariable("doSomething", res);
   

   

3. Run process

   

4. Proof of work:

   • Debug call after run the process:

     

   • stdout in console:

     

   • Variable has been committed inside completed process:

     

Conclusion

I recommend using a Spring Bean type of service task if you only need to call a method from a service, rather than relying on a script task worker. However, if you are developing the process during runtime, using a script task worker is acceptable.
