Loading Custom activiti.cfg.xml - spring

Question

I am learning activiti.
Where I created one java application in that I am using hibernate + Spring + activiti where we have activiti.cfg.xml.
I want to load only database details like datasource and hibernate properties programatically, other thing e.g asyncExecutorActivate, etc I want to do using activiti.cfg.xml.
e.g
Following need to set using Programatically
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="<set_Using_Program>" />
<property name="url" value="<set_Using_Program>" />
<property name="username" value="<set_Using_Program>" />
<property name="password" value="<set_Using_Program>" />
</bean>
This Information set using activiti.cgf.xml
<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration" />
</bean>
<bean id="runtimeService" factory-bean="processEngine"
factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine"
factory-method="getTaskService" />
<bean id="repositoryService" factory-bean="processEngine"
factory-method="getRepositoryService" />
</beans>
How to do?

Answer 1

You can simply inject your values from properties file and build your own engine based on them. such as data source. follow this tutorial
You can also build extensions on them see userguide

Answer 2

for Spring Boot you can configure process engine like this code. activitiproperties is a custom class that I write to get mail server parameters.
#Autowired
private SpringProcessEngineConfiguration springprocessengineconfiguration;
springprocessengineconfiguration.setMailServerHost(activitiproperties.getMailServerHost());
springprocessengineconfiguration.setMailServerPort(activitiproperties.getMailServerPort());
springprocessengineconfiguration.setMailServerUsername(activitiproperties.getMailServerUserName());
springprocessengineconfiguration.setMailServerPassword(activitiproperties.getMailServerPassword());
springprocessengineconfiguration.setMailServerDefaultFrom(activitiproperties.getMailServerDefaultFrom());
springprocessengineconfiguration.setMailServerUseSSL(activitiproperties.isMailServerUseSsl());
springprocessengineconfiguration.setMailServerUseTLS(activitiproperties.isMailServerUseTls());
