我尝试使用 spring/jpa/hibernate 和 GAE/Google Cloud SQL 进行简单测试。

但我找不到正确的配置，我总是不断得到：

单元测试 ：

@RunWith(org.springframework.test.context.junit4.SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext-persistence.xml" })
@TestExecutionListeners( { DependencyInjectionTestExecutionListener.class, TransactionalTestExecutionListener.class })
@TransactionConfiguration(defaultRollback = true)
@Transactional
public class ConfigurationTest  {

    @Test
    public void testConfig(){

    }

}

有任何想法吗 ？

谢谢

为时已晚，但也许它会帮助某人。
我发现了同样的问题，VM args在 JUnit 执行下不起作用。

解决方案是让我为测试定义另一个 entityManager/persistenceUnit。

关键是改变新testPersistence.xml的属性：

<property name="javax.persistence.jdbc.driver" value="com.google.appengine.api.rdbms.AppEngineDriver"/>
<property name="javax.persistence.jdbc.url" value="jdbc:google:rdbms:localhost:3306/DB_NAME" />

和

<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
<property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/DB_NAME" />

希望这可以帮助。
