I have a spring boot application with activiti integrated via org.acitviti.spring-boot-starter-basic.I created the activiti tables via sql scripts.

I imagine since you are using the spring boot starters, that you are using Community Edition. If not, please let me know as the answer is different for Community Edition and Enterprise Edition.

In order to access the process engine configuration when Activiti is initialized, you need to create a bean/component that implements the org.activiti.spring.boot.ProcessEngineConfigurationConfigurer interface.

e.g.

@Component public class MyProcessEngineCfgConfigurer 
implements ProcessEngineConfigurationConfigurer { 
  public void configure( SpringProcessEngineConfiguration springProcessEngineConfiguration) {
     ... // This is where we tweak the process engine configuration 
  }
}

The Spring boot starter AbstractProcessEngineAutoConfiguration class will look for this bean and if present will call the configure() method on it as soon as the SpringProcessEngineConfiguration is constructed.

The following github thread talks about this feature: Unclear how to configure activiti · Issue #5 · jbarrez/spring-boot-with-activiti-example · GitHub

Hope this helps,
Greg
