# Calculation Finite State Machine
Реализация State Machine на
базе [Spring State Machine](https://docs.spring.io/spring-statemachine/docs/current/reference/).
* [Cash Flow](images/Cash%20Flow%20State%20Machine.png)
* [VSSDV](images/VSSDV%20State%20Machine.png)
### Требования
* Сохранение и восстановление FSM из состояния в таблице `CalculationStatus`.
* Для ВССДВ используется State Machine с параллельными состояниями, в таблицу CalculationStatus записывается кортеж
состояний.
* Использование транзакционных действий при записи в `CalculationStatus`.
### Тестирование
Подготовка:
```shell
$ docker compose up postrges -d
$ ./gradlew clean build
$ ./gradlew bootRun --args='--server.port=8081'
$ ./gradlew bootRun --args='--server.port=8082'
$ psql -h localhost -p 5432 -U program services
services=> INSERT INTO calculation (uid, name, type, created_date, modified_date)
VALUES ('0df50a2c-45ef-45ff-b2c3-9f5c58e3e814', 'Calculation CF 1', 'CASH_FLOW', NOW(), NOW()),
('ef8ac5ac-77dd-48f8-ad9c-5b4496f05dc3', 'Calculation CF 2', 'VSSDV', NOW(), NOW()),
('ba012596-4be8-4c96-9721-07b7f9902a6a', 'Calculation VSSDV 1', 'VSSDV', NOW(), NOW());
```
Тестирование:
