@Transactional annotation is not working springboot

Question

I'm using springboot 2.3.0 with mongodb. @Transactional annotation is not working for me. It is not able to rollback the transaction in case of any exception. ps:Using mongoTemplate it is working.

Any help will be highly appreciated.

My controller class:

@PostMapping(value = "/employee/{employeeId}")
public String createEmployee(@PathVariable(value = "employeeId") String employeeId, @RequestBody EmployeePayload payload) {
    
    employeeService.createEmployee(employeeId, payload);
    return "employee successfully added";
}

My serviceImpl class

 @Override @Transactional(rollbackFor = {ArithmeticException.class}) public void createEmployee(String employeeId, EmployeePayload payload) { Employee employee = new Employee("1", "Robert", "24"); Document mongoDocument = new Document(); mongoTemplate.getConverter().write(employee, mongoDocument); MongoDatabaseFactory mongoDatabaseFactory = new SimpleMongoClientDatabaseFactory(properties.getUri() + properties.getDataBase() + properties.getDbFilter()); MongoDatabaseUtils.getDatabase(properties.getDataBase(), mongoDatabaseFactory).getCollection("employee").insertOne(mongoDocument); System.out.println(7 / 0); //To throw an exception }

My MongoConfig class

@Configuration public class MongoDBConfig {

    @Bean
    MongoTransactionManager transactionManager(MongoDatabaseFactory dbFactory) {
        return new MongoTransactionManager(dbFactory);
    } 
}

You are missing @EnableTransactionManagement annotation.
