我們的Spring Web應用程序的事務性JUnit測試失敗。事務性SpringJUnit4測試失敗
具體做法是:如果我單獨執行與Maven每個測試它們貫穿:
mvn -Dtest=Test1
mvn -Dtest=Test2
如果我執行
mvn -Dtest=Test1,Test2
我在一個測試中獲得了JPA錯誤:
Could not open JPA EntityManager for transaction; nested exception is
java.lang.IllegalStateException:
Attempting to execute an operation on a closed EntityManagerFactory."
type="org.springframework.transaction.CannotCreateTransactionException"
org.springframework.transaction.CannotCreateTransactionException:
Could not open JPA EntityManager for transaction; nested exception is
java.lang.IllegalStateException:
Attempting to execute an operation on a closed EntityManagerFactory.

如果我設置surefire插件爲每個測試重新創建整個JVM,他們也會遇到這種情況,這是一段瘋狂的時間。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>${maven.surefire.version}</version>
<configuration>
<reuseForks>false</reuseForks>
<forkCount>1</forkCount>
</configuration>
</plugin>
應用設置:
- 彈簧,用的Spring Roo
- 的EclipseLink如JPA提供商
applicationContext.xml中用於測試設置(從而proxymode = asjectJ!):

JUnit測試看起來像:
@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:META-INF/spring/applicationContext.xml",
"classpath:META-INF/spring/webmvc-config.xml" })
@TransactionConfiguration(transactionManager = "transactionManager")
@DirtiesContext
public class Test1 {
@Autowired
WebApplicationContext wac;
private MockMvc mockMvc;
@PersistenceContext
EntityManager entityManager;
@Before
public void setup() throws Exception {
this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
}
@Test
@Transactional
public void getJSONTest() throws Exception {
...
}
}
沒有任何人有任何想法,其中的兩個測試是如何連接?一個人必須關閉其他entityManager,但爲什麼和如何?
任何想法感謝!
EDIT1:擬議中刪除了@TransactionConfiguration和@DirtiesContext,但現在我得到一個
No transaction is currently active; nested exception is
javax.persistence.TransactionRequiredException
EDIT2:我找到了這個問題至今該訂單中,我執行測試戲劇一個洞。因此,測試不是彼此獨立的。我嘗試了幾次註釋和執行順序的排列,每次產生不同的錯誤/行爲。
眼下上一流水平的設置是:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:META-INF/spring/applicationContext.xml",
"classpath:META-INF/spring/webmvc-config.xml" })
@WebAppConfiguration
@Transactional
@DirtiesContext
我再次把@DirtiesContext註釋,因爲新初始化的背景下,似乎有時幫助。
很難在這裏追查真正的問題,但是我來到了一個具體問題:
我包我的測試類@Transactional,在我的測試方法我稱之爲
mockMvc.perform(MockMvcRequestBuilders.post(...))
,呼籲一個控制器方法。此控制器方法委託給另一個具有@Transactional方法的bean。在mockMvc.perform()返回後,我檢查單元測試天氣中的值是否寫入數據庫。我知道,只有在事務被提交給數據庫或者使用相同的Transaction/entityManager的情況下,這才能工作。測試方法的交易是否與被叫控制器一樣?還是我們在這裏討論兩個不同的實體管理器/交易?
對不起,「不接受「的答案,但我只注意到JPA錯誤消失了,但現在我有一個」異常說明:沒有事務處於活動狀態;「錯誤:/ – hFonti
嗯,你有@Transactional annotatinon嗎?你可以請張貼你的測試類註釋配置現在的樣子嗎? –
