如何在测试事务期间避免在Spring存储库中缓存实体 [英] How to avoid caching of entites in Spring Repository during a Transaction for tests

问题描述

我有一个这样的测试:

@Transactional
@Test
public void addRemoveTest() {
    MyEntitiy entity = new MyEntitiy ();

    entity = textureRepository.saveAndFlush(entity );
    TestTransaction.flagForCommit();
    TestTransaction.end();
    TestTransaction.start();
    final MyEntitiy loadedTexture = myEntityRepository.findOne(entity .getId());
}

这很好用.但是，当我删除事务的提交代码时，存储库在调用findOne()时将不会调用数据库.我能以某种方式强迫它使数据库调用我的测试吗?

This works perfectly fine. But when I remove the Committing code for the transaction, the repository will not call the database when calling findOne(). Can I somehow force it to make the database call for my Tests?

我希望我的测试不提交任何交易.

I prefer my test to not commit any transaction.

我无法通过Session清除缓存.而且我什至不确定清除会话是否有帮助.

I'm not able to get the Session to clear the cache. And I'm not even sure if clearing the session would help.

推荐答案

我知道的唯一方法是在调用查找程序之前先调用entityManager.clear().我认为您可以将EntityManager自动连接到测试中:

The only way I know is to call entityManager.clear() before calling the finder. I think you can autowire the EntityManager into your test:

@Autowired
private EntityManager entityManager;

您的测试将如下所示:

@Transactional
@Test
public void addRemoveTest() {
    MyEntitiy entity = new MyEntitiy ();

    entity = textureRepository.saveAndFlush(entity );
    entityManager.clear();
    final MyEntitiy loadedTexture = myEntityRepository.findOne(entity .getId());
}
