Java Firestore Template

자바에서 Firestore를 사용하기 위한 템플릿입니다.

사용법

1. Firestore 인스턴스 초기화

   InputStream credentialsStream = new FileInputStream("YOUR_FIREBASE_ADMIN_SDK.json");
   GoogleCredentials credentials = GoogleCredentials.fromStream(credentialsStream);
   
   FirebaseOptions options = FirebaseOptions.builder()
           .setCredentials(credentials)
           .build();
   
   FirebaseApp.initializeApp(options);

2. Data 생성

   @Getter
   @Setter
   @SuperBuilder
   @NoArgsConstructor
   @ToString(callSuper = true)
   @EqualsAndHashCode(callSuper = true)
   public static class Money extends Data {
       int money;
   }

3. Storage 생성

   Storage<Money> moneyStorage = Storage.of(Money.class);

4. 사용

   • Create

     Money money = Money.builder()
                           .id(uuid)
                           .money(1000)
                           .build();
     
     moneyStorage.create(money);

   • Read

     Money money = moneyStorage.get(uuid);

   • Update

     moneyStorage.update(uuid, prev -> prev.setMoney(prev.getMoney() + 1000));

   • Delete

     moneyStorage.delete(uuid);
