在使用Spring 3時，事務不會回滾@Transactional註釋

Question

爲了演示Spring中的事務支持 ，我使用了Spring（3.0版）'@Transactional'註釋，但無法正常工作（儘管看到過類似人們在此遇到的問題以及其他技術論壇）。

這裏是spring-application-context.xml我的Spring配置項：

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 
    <property name="dataSource" ref="dataSource"/> 
    </bean> 

    <tx:annotation-driven /> 

    <bean id="formatDao" class="com.gj.dao.FormatDao"> 
    <property name="dataSource" ref="dataSource"/> 
    </bean> 

這是我在我的測試類交易方法：

@Transactional(readOnly = true) 
    public class FormatDaoTest 
    { 

     private static ApplicationContext context = new FileSystemXmlApplicationContext(
     "c:\\catalogue\\src\\com\\gj\\conf\\spring-application-context.xml"); 

     public static void main(String[] args) 
     { 
    FormatDaoTest test = new FormatDaoTest(); 
    test.doTransaction(); 
     } 


     @Transactional(propagation = Propagation.REQUIRES_NEW, readOnly = false) 
     public void doTransaction() 
     { 

    IDao dao = (IDao) context.getBean("formatDao"); 

    Format newFormat = new Format(1, "Test Format 1"); 

    // Creating a single format 
    dao.create(newFormat); 

    List newFormatList = new ArrayList(); 
    newFormatList.add(new Format(2, "Test Format 2")); 
    newFormatList.add(new Format(3, "Test Format 3")); 
    newFormatList.add(new Format(4, "Test Format 4")); 
    newFormatList.add(new Format(5, "Test Format 5")); 

    // Creating a list of formats 
    dao.create(newFormatList); 

    List updatedFormatList = new ArrayList(); 
    updatedFormatList.add(new Format(1, "My Test Format 1")); 
    updatedFormatList.add(new Format(2, "My Test Format 2")); 
    updatedFormatList.add(new Format(3, "My Test Format 3")); 

    // Update a list of formats 
    dao.update(updatedFormatList); 

    Format updatedFormat = new Format(4, "My Test Format 4 with a long format description so allowed table column size is exceeded"); 

    // Update a single format resulting in a java.sql.SQLException: ORA-12899: value too large for column 
    // "RSSPPF1_OWNER"."FORMAT"."FORMAT_DESC" (actual: 88, maximum: 30) 
    dao.update(updatedFormat); 


     } 

    } 

以下SQL異常被拋出（因爲我所期望的）：

Exception in thread "main" org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [UPDATE FORMAT SET format_desc = ? WHERE format_id = ?]; SQL state [72000]; error code [12899]; ORA-12899: value too large for column "RSSPPF1_OWNER"."FORMAT"."FORMAT_DESC" (actual: 88, maximum: 30) 
    ; nested exception is java.sql.SQLException: ORA-12899: value too large for column "RSSPPF1_OWNER"."FORMAT"."FORMAT_DESC" (actual: 88, maximum: 30)

    ... 7 more 

但是，在異常被拋出後，交易會上不會回退，我可以看到以前的數據庫被拋出一直致力於FORMAT表外插 和更新之前：

FORMAT_ID FORMAT_DESC 
    1  My Test Format 1 
    2  My Test Format 2 
    3  My Test Format 3 
    4  Test Format 4 
    5  Test Format 5 

我本來期望看到沒有提交到數據庫這個異常以下。

有沒有人知道我要去哪裏錯了，我在這裏錯過了一些關鍵概念？

任何幫助將不勝感激！

Answer 1

@Transactional僅適用於Spring管理的bean（除非您配置了高級功能），而在您的情況下，FormatDaoTest不受Spring管理。

我想你可以做以下的快速修復：

public static void main(String[] args) { 
    FormatDaoTest test = context.getAutowireCapableBeanFactory() 
     .createBean(FormatDaoTest.class); 
    test.doTransaction(); 
} 

作爲一個更優雅的解決方案，你可以使用Spring TestContext框架，它支持事務感知測試開箱，見9.3.5.4 Transaction management。
