这是我在Stackoverflow中的第一个问题。
Spring JPA Hibernate存在很大问题。 我可以读取表格（通过我的实体中定义的@NamedQuery选择），但我无法将实体持久存储到数据库中。

当我执行单元测试时，它成功完成（不是异常或日志错误）。但是当我看到桌子时，桌子上没有新记录。
Hibernate的日志不显示INSERT语句。
有什么想法吗？我读了很多而没找到解决方案:(
答案 0 :(得分：1)
我更改了EntityManagerFactory的注入：
@Autowired
private EntityManagerFactory entityManagerFactory;
....
this.entityManagerFactory.getEntityManager();
....
标准JPA：
@PersistenceContext
private EntityManager entityManager;
完美无缺：3
答案 1 :(得分：0)
坚持后可以尝试冲洗吗？
@Override
@Transactional
public void create(GameUser gameUser) {
this.gameUserRepository.create(gameUser);
this.getEntityManager().flush();
}
答案 2 :(得分：0)
如果您没有收到任何错误，那么您的事务管理器似乎配置不正确，并且不会向您的数据库发送任何提交。
hidePred = [NSPredicate predicateWithFormat:@"hide != %@", [NSNumber numberWithBool:YES]]
还有一件事需要检查：确保@Transactional注释来自包org.springframework.transaction.annotation，而不是javax.transaction
答案 3 :(得分：0)
测试完成后，您在表格中看不到任何内容，因为SpringJUnit4ClassRunner会自动回滚。
