在使用Hibernate/Spring/Maven/MySQL進行測試之後，防止數據被刪除

Question

我正在使用Hibernate/Spring/Maven/MySQL和JUnit進行單元測試。直到昨天，即使在測試運行完成之後，我的測試數據仍然保留在數據庫中。我在今天配置了這個地獄，所有的數據在每次測試後都會被刪除。很確定，這不是bug，而是一個配置問題。不過，我迷路了。

appContext.xml：

感謝您的建議。

編輯---- 所要求的測試用例：

package de.test.base; 

import org.junit.runner.RunWith; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 
import org.springframework.transaction.annotation.Transactional; 

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration("/appContextMain.xml") 
@Transactional 
public abstract class SpringTestCase { 
}

    final Logger logger = null; 

    @Autowired

    @Autowired

    Trainee trainee = new Trainee(); 

    @Before

     this.trainee.setName("Name"); 
     this.trainee.setSurname("Surname"); 
     this.trainee = this.traineeDAO.save(this.trainee);

     BodSt bodSt = new BodSt();

     this.logger.info("BodSt size before: " + before.size() + " and after: " + after.size()); 
     Assert.assertEquals(before.size() + 1, after.size()); 
    } 
} 

Answer 1

在創建測試數據的測試用例上使用@Rollback（value = false）註釋可確保數據不會被刪除。

Answer 2

你能來運行測試的一個交易內，rollbacking呢？
