春季啓動1.5測試不回滾事務

2017-06-06 104 views

我開始一個簡單的Spring啓動項目+ JPA + Hibernate + Mysql。在開始編碼之前，我創建了一些非常簡單的測試，但不幸的是，behaiour不是預期的。這是我的測試類：春季啓動1.5測試不回滾事務

@RunWith(SpringRunner.class) 
@SpringBootTest 
@TestPropertySource(locations = "classpath:test.properties") 
@Transactional 
public class TenantTest { 

    @Autowired 
    private TenantRepository tenantRepository; 

    @Test 
    public void createTenant() { 
     Tenant tenant = new Tenant(); 
     tenant.setAddress("Street n.1"); 
     tenant.setAlias("tenant"); 
     tenant.setCity("Milan"); 
     tenant.setCountry("Italy"); 
     tenant.setEmail("[email protected]"); 
     tenant.setLandlinePhone("3902123456"); 
     tenant.setMobilePhone("39347123456"); 
     tenant.setName("Tenant 1"); 
     tenant.setType(TenantType.RESELLER); 

     Tenant savedObj = tenantRepository.save(tenant); 

     assertNotNull("Tenant null after save!", savedObj); 

    } 

    @Test 
    public void createTenantWithInvalidEmail() { 
     Tenant tenant = new Tenant(); 
     tenant.setAddress("Street n.1"); 
     tenant.setAlias("tenant"); 
     tenant.setCity("Milan"); 
     tenant.setCountry("Italy"); 
     tenant.setEmail("[email protected]"); 
     tenant.setLandlinePhone("3902123456"); 
     tenant.setMobilePhone("39347123456"); 
     tenant.setName("Tenant 1"); 
     tenant.setType(TenantType.RESELLER); 

     Tenant savedObj = tenantRepository.save(tenant); 

     assertNotNull("Tenant null after save!", savedObj); 

    }

根據Spring文檔（https://docs.spring.io/spring/docs/current/spring-framework-reference/html/integration-testing.html#testing-tx），每個測試應該回滾。相反在我的例子中，這不會發生。事實上，我有這個錯誤的第二個測試：

這很明顯，因爲事務沒有回滾。我春春的還印調試日誌說它是回滾事務：

嘗試使用'MySQL5InnoDBDialect'。你也可以指定數據庫平臺或數據庫，但不能同時指定。 –

@ M.Deinum我刪除了數據庫屬性，但不是那個問題。使用MySQL5InnoDBDialect它的作品！在我的情況下，我換成spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect spring.jpa.hibernate.dialect.storage_engine = innodb，因爲我使用的是Hibernate 5.2，並且您建議的值已被棄用。請張貼您的答案，以便我可以確認。另外，你有一個想法，爲什麼用InnoDB方言工作，而沒有？謝謝 – drenda

在你的測試課上添加'@ TransactionConfiguration'。看看：http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/test/context/transaction/TransactionConfiguration.html。 還提到它已被棄用，從Spring Framework 4.2開始，在類級別使用@Rollback或@Commit，在@Transactional中使用transactionManager限定符。 –

my.cfg設置爲MyISAM）。

確實支持事務的存儲引擎是InnoDB。

現在你基本上有2種解決方法。

  1. 升級MySQL到最低5.5.5（或更近）
  2. 使用正確的Hibernate方言

要指定您需要的spring.jpa.database-platform設置爲正確的類正確的方言。

spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect

設置此方言將強制執行存儲引擎InnoDB。

注意：您應該設置spring.jpa.database-platform或spring.jpa.databse，但不能同時設置（因爲後者將覆蓋方言！）。

如果您使用的是Hibernate 5.2。8或以上，你可以省略spring.jpa.database-platform，只設置spring.jpa.database（或讓它自動檢測）並將hibernate.dialect.storage_engine屬性設置爲innodb。 （另請參閱this blog）。

spring.jpa.database=MYSQL 
spring.jpa.properties.hibernate.dialect.storage_engine=innodb

提交事務和刷新/同步JPA持久性上下文是有區別的。刷新生存環境將生成的SQL寫入數據庫。這可以在由持久性提供者主要在事務提交時確定的任何時候發生。但是，當您使用在數據庫端a.k.a IDENTITY中生成的自動生成的標識符或執行查詢時，也可能發生這種情況。

因此，即使持久性上下文已被刷新，它也可能回滾交換。

即使是Spring日誌也表明測試事務正在回滾。與不產生異常的記錄嘗試並當在使用MySQL版本5.5.5 <則默認存儲引擎是MyISAM它不支持事務處理（或default-storage-engine財產本應回滾以及

我明白了，這很清楚。不幸的是，在2個不會產生異常的測試中，我找到了數據庫中的條目（我更改了ddl-auto來創建）。所以似乎還有其他錯誤。 – drenda

哪個PlatformTransactionManager爲您的應用程序上下文定義？ –

我正在使用Spring Boot和註釋。我沒有定義任何PratformTransactionManager。所以，我的猜測是使用默認的。 – drenda
