package com.example.template.service

import org.springframework.beans.factory.annotation.Autowired
import org.springframework.transaction.support.TransactionCallback
import org.springframework.transaction.support.TransactionTemplate

abstract class baseService {
    @Autowired
    private lateinit var transactionTemplate: TransactionTemplate

    protected fun  transaction(action: TransactionCallback) = transactionTemplate.execute(action)
}

package com.example.template.service

@Service
class TaskService(
    private val repository1: Repository1,
    private val repository2: Repository2,
    private val repository3: Repository3
) : baseService() {

    fun deleteByEntity(entity: Task) = with(entity) {
    	transaction {
	        id1?.let { repository1.deleteById(it) }
	        id2?.let { repository2.deleteById(it) }
	        id3?.let { repository3.deleteById(it) }
        }
