The project structure is as follows-

step 1:
Create a new maven spring boot project using https://start.spring.io/

step 2:
Add kie-ci dependency to pom.xml

step 3:
Create a model object named Test

step 4:
Create a .drl rules file under src/main/resources/META-INF/rules

package rules

import com.example.demo.Test

rule "sla for ui"
 when 
  testObject: Test(type=="ui")
 then
  testObject.setSla("15");
 end
rule "sla for be"
 when 
  testObject: Test(type=="be")
 then
  testObject.setSla("30";
 end

step 5:
Create a kmodule.xml file under src/main/resources/META-INF to create a kie session object.

<?xml version="1.0" encoding="UTF-8"?>
<kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule">
   <kbase name="rules" packages="rules">
        <ksession name="rulesSession"/>
    </kbase>
</kmodule>

step 6:
Create a controller class and initialize the kiesession object and fire all the rules.

//get the stateful session
  KieSession kieSession = kieContainer.newKieSession("rulesSession");
  kieSession.insert(test);
  kieSession.fireAllRules();
  kieSession.dispose();

step 7:
Create a kie container object in the main application class.

@Bean
 public KieContainer kieContainer() {
  return KieServices.Factory.get().getKieClasspathContainer();
 }

step 8:
Test the application using http://localhost:8080/getSla?type=ui
