Try adding below in spring-config.xml:

<context:component-scan base-package=“your.packagename.contatining.EmployeeDetailsDao” />
<mvc:annotation-driven />

and changing @Transactional in your CommonEmployeeService with @Transactional(rollbackFor=Exception.class, propagation=Propagation.REQUIRED) as below

@Service
public class CommonEmployeeService {

    @Autowired
    EmployeeDetailsService detailsService;

    @Autowired
    EmployeeService service;

@Transactional(rollbackFor=Exception.class, propagation=Propagation.REQUIRED)
    public boolean insert(Employee e, EmployeeDetails details) {
        service.insert(e);
        detailsService.insert(details);
        return true;
    }
}
