Spring #Transactional annonation not working - spring-boot

Question

I am facing an issue when I use a #Transactional annotation in a class which is extended by Service class. I know that Spring does Transaction Management only when a method is invoked by a Proxy but my problem is because of this annotation I am not able to get another Service class's property's value when accessing by object directly (property is public), but same I am able to fetch through getter method.
Controller
package com.springbootdemo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class DemoController {
#Autowired
Service1 service1;
#GetMapping("/")
public void index() {
service1.doSomething();
}
}
Service1
package com.springbootdemo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
#Component
public class Service1 {
#Autowired
Service2 service2;
public void doSomething(){
service2.setSname("Hello");
System.out.println("sname==> "+service2.sname);
System.out.println("getSname==>"+service2.getSname());
}
}
UtilBean
package com.springbootdemo;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
#Component
public class UtilBean {
#Transactional(propagation = Propagation.REQUIRES_NEW)
public String appendString(String s1) {
return " Hi "+ s1;
}
}
Service2
package com.springbootdemo;
import org.springframework.stereotype.Component;
#Component
public class Service2 extends UtilBean{
public String sname;
public String getSname() {
return sname;
}
public void setSname(String sname) {
this.sname = sname;
}
}
