Весна 4.3.0.RELEASE + Hibernate 5.2.0.Final - вставлять повторяющиеся строки каждый раз

2016-07-08 3 views

Hi, Существует много вариантов этой проблемы, но все ваты, чтобы исправить это, потерпели неудачу. Каждый раз, когда я вставляю объект, он вставляет мне дубликаты данныхВесна 4.3.0.RELEASE + Hibernate 5.2.0.Final - вставлять повторяющиеся строки каждый раз

Я попытался изменить функцию добавления с помощью функции «persist (role)» или «saveOrUpdate (role)», но это не работает.

** update: если я добавляю fucntion "if (event.getApplicationContext(). GetParent()! = Null)" это временное решение.

таблицы БД:

mysql> select * from role; 
+----+------------+ 
| Id | Name  | 
+----+------------+ 
| 1 | ROLE_USER | 
| 2 | ROLE_ADMIN | 
| 3 | ROLE_USER | 
| 4 | ROLE_ADMIN | 
+----+------------+ 
4 rows in set (0.00 sec)

Что может быть проблема?

в вашем примере вы сохраняете 2 объекта. в чем проблема? – Apostolos

Уверены ли вы, что вы не получили два события контекстного контекста? И глупый вопрос, но вы начали приложение только один раз? –

Во-первых, @Column(unique=true) на RoleEntity.Name

Тогда Вы можете (уродливые варианты, но быстро):

-catch исключение, когда контекст называется второй раз

-do некоторые boolean fired чек

. Проведите различие между тем, какой контекст освежен и пропустите

@Component  
public class ApplicationStartup implements ApplicationListener<ContextRefreshedEvent> { 
    private static boolean fired = false;  
    @Override  
    public void onApplicationEvent(final ContextRefreshedEvent event) {  
     if (!fired) { 
     //Your db inserts go there  
     System.out.println("Something simple like that, could do the job i think.");  
     fired = true;  
     }  
    }  
}
