Hibernate在模式導出時掛起

我的單元測試使用內存中的HSQLDB以及由Hibernate生成的即時模式。現在在特定的情況下（現在還沒有詳細說明，與@ManyToMany關係有關），模式導出會掛起。當測試用例沒有使用特定的關係時，它不會掛起。Hibernate在模式導出時掛起

記錄時掛起：

上的BookInfo特定部分映射（Scala中，但也可以讀取如Java）：

 
    @S.ManyToMany(
    fetch = FetchType.LAZY, 
    cascade = Array(CascadeType.PERSIST) 
) 
    @S.JoinTable(
    name = "BookInfo_Author", 
    joinColumns = Array(new S.JoinColumn(name = "bookInfo")), 
    inverseJoinColumns = Array(new S.JoinColumn(name = "author")) 
) 
    @BeanProperty 
    var authors: java.util.Set[Author] = new java.util.HashSet[Author]()

測試用例創建一個BookInfo對象，設置一個作者，並使用Spring的Hibernate模板的persist方法保存它即最後，在關閉會話時，模式導出會掛起。

有什麼想法？

請使用HSQLDB 2.1一起與Hibernate 3.6或更高，以避免已知的相容性問題。我不知道這是否能解決問題。

謝謝你的提示，我試過HSQLDB 2.1但症狀是一樣的。與Hibernate 3.6.2捆綁在一起的方言似乎和HSQLDB一樣。現在我切換到H2數據庫（1.3.153）和H2Dialect，到目前爲止效果很好。 – ron 2011-03-17 08:55:32

謝謝。當我們進行下一輪Hibernate測試時，需要注意什麼。 – fredt 2011-03-17 10:33:36

的原因對我來說，我沒有回滾失敗的事務（異常時），這可能留下一些處於鎖定狀態的表。確保回滾解決了我的問題。

PS：我用的是MySQL數據庫

對我來說也掛單元測試運行過程中打印以下行的後面：

[INFO|org.hibernate.tool.hbm2ddl.SchemaExport|JCLLoggerAdapter] exporting generated schema to database

我有多個測試類。因此，在每個測試類中，我使用AnnotationConfiguration在@BeforeClass靜態方法中創建了一個新的SessionFactory對象，如下所示。

public class MyClassTest{  
    private static SessionFactory testSessionFactory = null; 

    @BeforeClass  
    public static void initialize() { 
     Properties testHibernateProperties = new Properties(); 
     // set testHibernateProperties 
     AnnotationConfiguration configuration = new AnnotationConfiguration().addProperties(testHibernateProperties) 
         .addAnnotatedClass(someAnnotatedClass.class); 
     testSessionFactory = configuration.buildSessionFactory(); 
    } 

    // Adding this in each test class creating SessionFactory solved the problem 
    @AfterClass 
    public static void destroy(){ 
     testSessionFactory.close(); 
    } 
}

我沒有任何測試類顯式關閉SessionFactory的。對我來說，它解決了這個問題，當我開始關閉sessionFactory明確地顯示在銷燬方法。
